Fiber Hardware
The term “fiber” is used to refer to all the hardware needed for the three basic
types of connections used to form multi-PN systems. Fiber administration
specifies the endpoints to be connected, optional DS1 CONV locations, and
parameters for DS1 facility line encoding and equalization. The three connection
types are:
1. EI-to-EI or EI-to-SNI intercabinet hardware
2. EI-to-SNI or EI-to-EI intracabinet hardware
3. EI-DS1CONV or SNI-DS1CONV hardware
EI-to-EI or EI-to-SNI Intercabinet Fiber-Optic
Cables
EI-to-EI or EI-to-SNI intercabinet connections are implemented by installing a
lightwave transceiver on the I/O connector plate for each of the administered fiber
endpoints. Each lightwave transceiver has a receive and a transmit connector for
either a 62.5-micron or 50-micron fiber connection. Standard fibers are available
in various lengths up to 150 feet (46 m) for single-mode fiber and up to 200 feet
(61 m) for multimode fiber. These fibers are used to connect lightwave
transceivers to each other when they are close enough together, or to optical
cross-connect facilities for greater distances.
The lightwave transceivers are powered from I/O connector plate leads attached
to TN570 Expansion Interface circuit pack or a TN573 SNI circuit pack. The
transceivers include loop-around capabilities to support fiber fault isolation. Either
of two different 9823-type multimode transceivers may be used, depending upon
the length of the fiber (table below), or the 300A single mode fiber transceiver.
The transceivers at each end of a given fiber should match.
