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. Typical fiber ports of these multiplexer are FC, SC or ST, interfaces are RS232, RS422 or RS485, which can be customized by users for actual demand.
Now, in the following text, let’s overview FiberStore four types of digital video multiplexers: Video multiplexers, video & audio multiplexers, video & data multiplexers, video & audio & data multiplexers.
1-64 Channel Video Multiplexers
Video multiplexers are built on Coarse wavelength division multiplexing (CWDM) and can encodes multi-channels video signals and convert them to optical signals to transmit on optical fibers. It handled several video signals simultaneously, and can also provide simultaneous display and playback features. We provide video multiplexers in different channels such as 1, 2, 4, 8, 16, 24, 32, 64 channels. They are available in both color and black and white video multiplexers, digital video multiplexers and processors. With a video multiplexer, users can record their combined signals on the VCR or wherever else they want to record. Our video multiplexer help users built a cost effective network system with the best process control and quality assurance.
Digital multiplexer has two VCR IN connections and two VCR OUT connections. There is one pair of VCR IN/OUT 4-pin DINI connectors (Y/C) and one couple with BNC connections (composite video). The VCR IN connectors is used to connect the multiplexer to a VCR which will be used to playback recorded images. Connect the Video OUT connector on a VCR to one of the VCR IN connectors on the multiplexer. The VCR OUT connectors are used to connect the digital multiplexer to a VCR which will be used to record video. Connect the Video IN connector on a VCR to one of the VCR OUT connectors on the multiplexer.
Video Data Multiplexers
Video data multiplexers are based on digital video technology to provide fiber optic transmission of video and return or bidirectional data signals in demanding environments. They can provide highly reliable data transmission and expandable data capacity over fiber optic cables up to a few tens of kilometers. The video data multiplexers simultaneously transmit multi-channel 8-bit digitally encoded broadcast quality video over one multimode or single mode optical fiber.
This module is directly compatible with NTSC, AL, or SECAM CCTV camera systems and support RS-485, RS-422, and RS-232 data protocols. These muxes are typically used with cameras that have PTZ capability. The plug and play design ensures adjustment-free installation and operation. LED indicators are provided for instant monitoring system status.
We supply video & data multiplexer in channels includes 1, 2, 4, 8, 16, 24, 32 channel. Typical installation utilizes the transmitter unit at the camera end of the link, and connects via a single fiber optic cable, to a receiver unit at the monitoring end of the link. These Video & Data multiplexers are suitable for concentration management in 1U/2U/4U Racks, and we also can supply the rack chassis for you.
Video & Audio Multiplexers
Video and Audio Multiplexer combines digital video with digital audio to form the embedded signal. It has optical remote monitoring capabilities so that operation can be controlled remotely. The audio video multiplexer can simultaneously transmit 1-64 channels of 8-bit digital encoded broadcast quality video/unidirectional or bidirectional audio signals over multimode or single mode optical fiber. These multiplexers are used in applications where the cameras have P/T/Z capabilities.
We supply video & Audio multiplexer in different channels such as 1, 2, 4, 16 channels, they are ideal for applications of security monitoring and control, highway, electronic policy, automation, intelligent residential districts and so on.
Video & Audio & Data Multiplexers
Video & Audio & Data Multiplexers transmit 1-64 channels of 8-bit digitally encoded broadcast quality video / return or bidirectional data / unidirectional or bidirectional audio over one multimode or single-mode optical fiber. These multiplexers are used in applications where the cameras have P/T/Z capabilities. With Plug and Play design, it can convert, integrate, groom and multiplex multiple video/audio/data streams effortlessly.
The Video & Data & Audio Multiplexers are ideal for a wide range of multiplexing and remultiplexing applications including Broadcast /Studio, CCTV audio and Professional AV applications.
FiberStore is a leading global supplier of telecommunications solutions for the electric utility, pipeline, transportation and industrial applications. This powerful family of optical multiplexers permits consolidation of all telecommunications requirements into a single, integrated network.
