Several Digital Video Multiplexers Types from FiberStore


As we know, a fiber optic multiplexer is a device that processes two or more light signals through a single optical fiber. It is introduced as an effective solutions to a fiber’s transmission capacity using different techniques and light source technologies. By using a multiplexer, media or data signals can be forwarded further, more securely with less electromagnetic and radio frequency interference.

The so called WDM (Wavelength Division Multiplexing) utilizes the total available pass band of an optical fiber. It assigns individual information streams into separate wavelengths, or portion of the electromagnetic spectrum. Frequency and wavelengths can be regarded as the same concept. The only difference is the frequency is typically used to describe the radio carriers. Frequency division multiplexing assigns each signal a distinctive frequency.

Digital video multiplexer is a typical fiber optic multiplexing devices for video and data signal’s fiber optic transmission. Digital video technology emerged as the ultimate facilitator of surveillance needs and has played an important role in the security area, that enables flexible, real-time, highly manageable and tunable solutions. Digital video multiplexer combined with this one-up digital uncompressed technology with WDM technology, make it possible to extend video and data service up to 100km distance simultaneously through one single fiber, and get the real-time high-definition video on the receiver side. This device is usually used for security application to control and monitor video cameras signals in airports, train station and public hotspots.

FiberStore fiber optic digital video multiplexer adopt the advanced international digital video and coarse wavelength division multiplexing (CWDM) technology, these multiplexers can transmit from 1 channel video & audio & data channel to max 64 channel signals in different optical distances. These video multiplexer are single mode and multimode fiber type with multichannel track mount or standard units. Insert card version is also available, which can be inserted into our 16-slot, 19inch 2U or 4U rack-mountable card cage for 10-digit coding and non-compression video transmission.

The 100G Industry Chain Still Needs To Improve


With the outbreak of emerging businesses such as high-definition video, social games, cloud computing and Internet of things, explosive growth of Internet content, so that the needs of next generation of Ethernet is increasing. Although the 40G/100G standards have been promulgated, the demand is also constantly stimulated, operators also verified the 100G with a commercial ability, but its scale popularity seems to have a distance, especially for 100G. What is the reason hindering the popularization, in technically what need to improve? When can really go the way of 100G?

The too high cost hinders 100G popularity And market maturity needs 3 years

China Telecom Technology Committee Director Wei Leping said, to achieve the scale of promotion, the cost of 100G applications should be controlled at as 5-6 times as the cost of 10G, there is a certain distance currently. Ruijie experts said, from the point of the cost of fiber optic transceiver, 100G module costs several times higher than the cost of 10G transceiver. It also requires the upstream and downstream of the industrial chain complement each other, continue working hard in chip integration, integration of optical module miniaturization and system design, to achieve cost reduction of the overall product. In addition, the architecture design of network manufacturers are also important factors, the role of the scale cost reduction such as supporting cables, wiring and tools also can not be ignored.

Overall, the 40G and 100G markets are in the early stage of market, but in contrast, the growth rate of 40G is faster than 100G, for example, Ruijie has made a considerable number of 40G commercial cases.

While the 100G standard has completed, but there are still not small challenges in the core of the optical module/high-speed signal processing technology, 100G commercial products also just launched by manufacturers. Therefore, experts believe that, the mature of 100G market is expected to take at least three years.

As we all know, the optical module technology cost is the key of the whole 100G system cost. But the 100G optical module devices are mainly controlled by foreign companies, although there are some Chinese enterprises introduced the 100G optical modules, but the quantity is too small, which virtually increases the 100G system cost.

There are still defects in technical and need to further improve the industrial chain

The 100G industrial chain including chip, optical devices, router to optical transmission system, and even the deployment, but the current situation is that, in the fiber optic module, the high-end core technology are basically controlled by foreign countries. Many experts said, the Chinese module makers have not domestic semiconductor chip production technology,  no continuous wavelength tunable lasers and high-end modulator chip, the manufacturer can do 100G optical devices is rare. Although there are more and more manufacturers to join this camp now, but many companies just re-processing of imported products, the lack of core technology, so there is no competition.

In addition to the short supply and not enough maturity of chip, optical devices and so on, some experts pointed out, the 100G industry chain supporting needs to be further improved, not only because the 100G optical network construction was just started, but also because the development of the 100G still faces challenges from the technology and market, for example, still exist cognitive gap in the line, construction, adjusting and testing, industry chain parties need to work together.

40/100G complement each other

Demand determines the market. From the current applications, in addition to some large data centers, the vast majority applications do not need the 100G bandwidth now, the bandwidth of 40G is sufficient; while the 40G products are more cost-effective than 100G products, and is expected to last a period of time, so the 40G products develop more smoothly than 100G in the moment. But apparently, the scene requires higher performance is relatively urgent demand for 100G, typical scenes such as super computing, cluster computing, etc. In the future, 40G and 100G will complement each other, service users in different application scenarios.

Silicon Photonics Lead The Trend Of 100G Network


FiberStore news, when assembled eliminated pure handmade reliable optical components containing hundreds of optics, steering the occasion of silicon photonics technology, the industry will enter a new better world. On the other hand, switching network upgrade from 10G to 100G, even when eventually reach 1TB, will also face tough challenges from silicon photonics technology. Some optical function is easy to realize by silicon, but some are not. In fact, the entire optical engine must be integrated in silicon platform.

Optical engine can handle multiple high-speed electrical channels, converts it to optical signal, then together the information on these channels, through an fiber optic to transmit the information to any location ─ ─ distance from near to the next frame or as far as across the entire data center from the other end. At the receiving end, optical engine will flow received light streams separate into different channels, and then converted back to radio channel. In the data center, optical engine used for connecting the cluster switches and routers, which is a low power consumption, smallest pluggable transceiver technology; optical engine is also used in active optical cable to connect to the server and switch. In addition, the optical engine soon will also be embedded into the splint (mid-board) in order to reduce the consumption of board to board application and increase the density.

However, integrating optical functions on CMOS platform will encounter many challenges, which is original used to realize electric function design. Take a look at each key photoelectric function and the challenges of its fully integration in a CMOS platform.


Laser provides fiber optic light source for the optical engine, but to some data centers, using laser is too expensive. Kotura has developed chip function by using low-cost low-speed laser. Laser is a type of optical component which has not achieved single-chip integration, but the latest development of laser and array of flip chip bonding technology, have made it into a large number of low-cost manufacturing process. Chip functions removed the lens, isolator and beam collimator needed by traditional laser subassembly. The design of Kotura laser removed the expensive sealed package. In the automated assembly platform, just a few seconds for the array laser entire fabric and welded to silicon photonic chip, but also overcome the difficult problem of low-cost light source integrated in the chip.

The real value of fiber optic network is the ability to combine multiple wavelengths of light into one entity channel. To the 100G interconnection,the use of this called wavelength division multiplexing (WDM) parallelism, put the light combination of four wavelengths in a fiber. Of course, the four parallel fiber channel can work, but this increases the cost of network, but also a waste of bandwidth of fiber optic. WDM makes the use of same data center architecture to expend become possible, in order to support more channels in the future.

Because WDM requires both specific wavelength and multiplex wavelength laser, and therefore using silicon photonics to achieve is not easy. Nevertheless, the industry still don’t want to use the expensive specific wavelength laser, which is commonly used in telecommunications network. A better solution is to use a universal laser, through integration of optical switch reflector in the silicon chip changes universal laser into specific wavelength laser. By changing the position of the reflector, Kotura will make each gain chip becoming a unique specific wavelength laser.

Transmode iAccess Addresses Large-scale Optical Access with WDM-PON


Transmode Systems AB says unveiled its iAccess portfolio, which leverages its iWDM-PON offering to help service providers roll out Ethernet access networks for applications such as business Ethernet and mobile backhaul services.

The iAccess package combines a new compact, low-cost network interface (NID) with the company’s I-WDM – PON hardware and Enlighten multi-layer network management system to provide what Transmode asserts is a low-cost, simple to install/configure/manage, and highly scalable approach to last mile Ethernet applications. The systems use a “remote port” architecture which makes all NIDs into extensions of the Ethernet Muxponder to which they are connected.

With the remote port architecture, the NID automatically takes device and service configuration data from the network when it is connected. This removes the need for a separated IP address for each NID, saying these sometimes scare resources. Coupled with the colorless optical layer through the WDM-PON optics, iAccess creates a highly automated, simple to operate, and scalable system, according to Transmode. This is particularly true in comparison to other approaches that are either derived from more complex and expensive optical access platforms or are based on simple hardware designed for residential applications, the company adds.

The iAccess is thus ideally suited to the delivery of Ethernet-based services that need to scale to large volumes or where simplicity is key. Transmode continues. Installation procedures are quick and simple and Enlighten allows operators to create service templates to speed up deployment of multiple identical or similar services – enabling operators to minimize open costs in addition to the lower initial capex costs.

Sten Nordell, Transmode’s CTO, said, “The new iAccess solutions is a great step forward in terms of simplifying and scaling Ethernet access networks while also enabling network operators to hit the right price points for these high volume services. We have created a real plug-and-play solution where the WDM-PON enabled NID is simply connected to the access fiber, powered up and then services are automatically created. This enables operators to quickly roll out new services with the right level of carrier class functionality such as Metro Ethernet Forum Carrier Ethernet 2.0 services.”

10G EPON Shipments Will Keep Growing


FiberStore news, with the rapid global deployment of FTTH, PON global market scale is constantly expanding, but the current PON market growth is beginning to slow down. In the recent “2013 China Optical Network Seminar”, Ovum principal analyst Julie Kunstler, said in an interview, during 2011-2012, the global GPON / EPON OLT has begun to decline in shipments, the total revenue of PON equipment market is also declined.

However, although the growth of entire PON market started to slow down or even a decline, but 10G PON market has begun to be favored. Julie Kunstler said that, although it is not completely sure which sort of next generation PON technology will become the mainstream in the future, but in Ovum’s expectations, the shipments of 10G EPON OLT will maintain a growth trend.

As for the Chinese broadband access market, Julie Kunstler believes that, due to the different wiring conditions of each region and each district, the future Chinese FTTx market penetration is expected to reach 40% -50%, the future will be a variety of access technologies co-exist, including PON, ADSL, VDSL, etc.

Julie Kunstler pointed out that, 2012 was the first year GPON OLT shipments beyond that of EPON, but the OLT total market has already begun to decline. Data show that, in the first quarter of 2013, EPON OLT shipments decreased 7%, compared to the same period down 46%; GPON OLT shipments decreased by 9%, an increase of 28%. In revenues, in the first quarter of 2013, EPON revenue decreased 25%, down 46%; GPON revenues decreased 29 percent, an increase of 3%.

Ovum predicts that, in the next few years, global GPON / EPON OLT shipments will further decline, it will be expected to from 41 million in 2012 decline to 13 million in 2018. At the same time, in 2012 GPON / EPON ONT / ONU’s shipments increased 43 percent compared to 2011, 2012 EPON ONT / ONU shipments still ahead of GPON ONT / ONU shipments, in 2013 GPON ONT/ONU shipments will just run after EPON.

Although entire PON market growth started to slow down or even a decline, but 10G PON market has begun to rise. Julie Kunstler said that, although what sort of future generation PON technology will become the mainstream is still not completely sure, but in Ovum’s expectations shipments of 10G EPON OLT will maintain a growth trend, and its application scenarios will be mainly reflected in FTTB, mobile backhaul, etc. Ovum forecasts, 10G EPON OLT’s shipments will maintain growth trend in 2018 will reach 500 thousand, 10G GPON OLT’s shipments will still be relatively small.
