Some Fiber Optic Cable Type Introduction


Fiber optic “cable” refers to the complete assembly of fibers, other internal parts like buffer tubes, ripcords, stiffeners, strength members all included inside an outer protective covering called the jacket. Fiber optic cables come in lots of different types, depending on the number of fibers and how and where it will be installed. It is important to choose cable carefully as the choice will affect how easy the cable is to install, splice or terminate and what it will cost. Next, we will introduce 5 types of fiber optic cable in communication.

Distribution Cable

When it is necessary to run a large number of fibers through a building, distribution cable is often used. Distribution cable consists of multiple tight-buffered fibers bundled in a jacket with a strength member. Typically, these cables may also form subcables within a larger distribution cable.

Distribution Cable

Distribution cables usually end up at patch panels or communication closets, where they ar hooked into devices that communicate with separate offices or locations. These fibers are not meant to run outside of office walls or be handled beyond the intial installation, because they do not have individual jackets.

Distribution cables often carry up to 144 individual fibers, many of which may not be used immediately bu should be considered for future expansion.

Breakout Cable

Breakout cables are used to carry fibers that will have individual connectors attached, rather than being connected to a patch panel.

Breakout cables consist of two or more simplex cables bundled around a central strength member and covered with an outer jackets. Like distribution cable, breakout cables may be run through a bulding’s walls, but the individual simplex cords can then be broken out and handled individually.

As is the case with distribution cable, breakout cables may end up in communication closets, but in the case of breakout cables, users can manmually change connections. Breakout cables may also be used to connect directly to equipment.

Armored cable

Armored cable, addresses the special needs of outdoor cable that will be exposed to potential damage from equipment, rodents, and other especially harsh attacks.

Armored fiber cable consists of a cable surrounded by a steel or aluminum jacket which is then covered with a polyethylene jacket to protect it from moisture and abrasion. It may be run aerially, installed in ducts, or placed in underground enclosures with special protection from dirt and clay intrusion.

Messenger Cable

When a fiber optic cable must be suspended between two poles or other structures, the strenth members alone are not enough to support the weight of the cable. Installers must use a messenger cable, which incorporates a steel or dielectric line known as a messenger to take the weight of the cable. The cable carrying the fiber is attached to the messenger by a thin web an hangs below it.

Also called Figure 8 Fiber Optic cable for the appearance of its cross section, messenger cable greatly speeds up installation of aerial cable by eliminating the need to lash a cable to a pre-run messenger line.

In applications that will run near power lines, the dielectric messenger is ofen used to minimize the risk of energizing the cable through induced current, which is created when the electrical field from a high voltage alternating current line expands and contracts over a nearby conductor. If a conductive cable is close enough to the alternating current, the induced current may be srong enough to injure someone working near the cable.

It’s a good practice, in fact, to use dielectric strength members wherever tension considerations permit, as this will help avoid any potential conductivity problems in the cable.

Hybrid cable

Hybrid cable, as applied to fiber optics, combines multimode and single-mode fibers in one cable. Hybrid cable should not be confused with composite cable, although the terms have been used interchangeably in the past.

High Density MTP Cables Assemblies and MTP Cassettes


IT operations are crucial to the organization for business continuity. Data centers are the central location for data interchange in IT operation of organizations and networked server farms. Ribbon fiber cables, array-based fiber connectors, and packaged breakout assemblies provide modular small form factor connectivity and enable fast, reliable interconnection of fiber optic links in high-density data center environments. Higher bandwidth requirement for 10G/40G/100G parallel optics, requirement to reduce cable size for better air flow, structured zone approach, reduction in rack space, higher density of servers and ports and reduction in installation time has brought in requirement for factory terminated high density cabling solutions. Factory terminated cable systems reduce installation time and offer scalable design and implementation. The following are MTP cable and high density MTP cassettes from FS.COM.

High Density MTP Cassette

MTP Cassette modules provide a secure transition between MTP and LC or SC discrete connectors. They are used to interconnect MTP backbones with LC or SC patching. LC to MTP and SC to MTP Fiber module provides a quick and efficient way to deploy up to 24 LC or 12 SC fiber ports in a single module. This factory terminated and tested ports are protected within the housing for reliably high performance and simply connected via 12-strand MTP ports. Modules are available in OM3, OM4 & SM fiber.

FS.COM MTP cassettes are enclosed units that contain 12 or 24–fiber factory terminated fan-outs inside. These cassettes serve to “transition” small diameter ribbon cables terminated with an MTP connector to the more common LC or SC interface used on the transceiver terminal equipment.

High Density MTP Cables

The fan-outs typically incorporate SC, LC connectors plugged into adapters on the front side of the cassette and an MTP connector plugged into an MTP adapter mounted at the rear of the cassette. One or more MTP fan-out assemblies may be installed inside the cassette to connect up to two 12-fiber ribbon cables for a total of 24 fibers. Alignment pins are pre-installed in the MTP connector located inside the cassette. Now the following is the MTP trunk cable.

Pre-connector MTP Cables are made up of 12, 24, 48 fiber LSOH jacketed micro cables terminated at both ends with MTP® Connectors (without pins). These are used as the backbone or horizontal cable interconnections. These plug and play solutions with micro core cable maximize bend radius and minimize cable weight and size. MTP Trunk Cable is factory pre-terminated, tested and packed along with the test reports. These assemblies are available in OM3, OM4 and SM fiber. Standard lengths of 5, 10, 25 meters are available. Custom lengths are also available on request. The MTP cables are packed as coils in lengths up to 50m long and on reels.

High Density MTP Breakout Cable

MTP Breakout Cable is a type of fan-out fiber optic cable ideal for data distribution to patch panels. These can be configured with 12 fiber, 24 fiber, and 48 fiber MTP connectors. They are available in both male and female MTP connectors, and also come with LC, SC, ST, and FC connectors on the fan outside.

Pre-connector MTP breakout cable assemblies are designed for high density applications which require high performance and speedy installation without onsite termination. MTP breakout cable is made up of 12 LSOH jacketed cable terminated at one end in MTP connectors, through a bifurcation unit, to SC or LC connectors terminated on 2mm OD simplex cables. These are used to connect equipment in racks to MTP cables. MTP cables are numbered for full traceability. Available in 12 core configuration, these space-saving assemblies come with either MTP Male or MTP Female Connectors on one end and LC or SC Connectors on the other end. They are available in OM3, OM4 or SM fiber in lengths of 5, 10, 25 meters, custom lengths are available on request.

We offer a wide range of MTP Cables including Trunk Cables,  MTP to LC breakout cables and MTP cassettes (or patch panels). All the assemblies are fully compliant with IEC Standards 61754-7 and TIA 604-5. We also provide Customized Service such as optional fiber counts, cable types and lengths etc.
