Fiber Patch Cables—Features, Applications and Types

Posted on by FS.COM

Fiber Patch Cables, also known as fiber jumpers or fiber patch cords, are used to connect fiber optic equipment to fiber optic cross-connects, inter connects, and information outlets. Having a thick layer of protection, it is used to connect the optical transmitter, receiver and the terminal box.

Fiber patch cable Features:
1. Low insertion loss and High Return Loss;

2. Fully compliant with standards of IEC and YD-T826/1996;

3. Temperature stability: Operating temperature: -20 to +75°C;

4. High durability, more than 500 times mating;

5. Individual package with detail information labe.

Applications of fiber optic patch cords:
FTTH application;

Premise installations;

Data processing networks;

Wide Area Networks (WANs);

Telecommunication networks;

Industrial, mechanical and military.

General Types Of Fiber Patch Cable

Generally there are two types of fiber optic patch cords: single mode fiber optic patch cords and multimode fiber optic patch cords. The word mode means the transmitting mode of the fiber optic light in the fiber optic cable core. Single-mode fiber is generally yellow, with a blue connector and a long transmission distance. Multi-mode fiber is generally, orange or grey, with a cream of black connector and a short transmission distance.

Single mode fiber optic patch cord has a small core and only one pathway of light. With only a single wavelength of light passing through its core, single mode realigns the light toward the center of the core instead of simply bouncing it off the edge of the core as with multimode. Single mode fiber patch cable is typically used in long-haul network connections spread out over extended areas–longer than a few miles. For example, telecommunications use it for connections between switching offices. Single mode cable features a 9-micron glass core.

Single-mode fiber cable is primarily used for applications involving extensive distances. Multimode fiber, however, is the cable of choice for most common local fiber systems as the devices for multimode are far cheaper.

Multimode fiber optic patch cord has a large-diameter core that is much larger than the wavelength of light transmitted, and therefore has multiple pathways of light-several wavelengths of light are used in the fiber core. Multimode optical fiber patch cords can be used as cross connect jumpers, equipment and work area cords, used for most general fiber applications. Use multimode fiber for bringing fiber to the desktop, for adding segments to your existing network, or in smaller applications such as alarm systems. Multimode cable comes with two different core sizes: 50 micron or 62.5 micron.

Special types of fiber optic patch cables:
FTTH Patch Cables;

Polarization Maintaining PM Fiber Patch Cables;

Mode conditioning fiber optic patch cables (mode conditioning patch cord, mode conditioning cable);

Pre-terminated pigtail (fiber pigtails, fiber pigtail, fiber optic pigtail, fiber optic pigtails).

Fiberstore offers fiber optic patch cables with different fiber connector types, low insertion loss and low back reflection. FiberStore Technology fiber patch cables are widely used in applications of Telecommunication Networks, Gigabit Ethernet and Premise Installations.
