2.2 Fibre Optic Cable & Connectors
2.2.1 Connector and Cable Types
All ViaLite Ethernet Transceiver modules use singlemode (9µm/125µm) cable terminated with either
FC/APC or E2000/APC optical connectors. Cross-site fibre optic cables are available from PPM as
either standard patch leads or heavy-duty multicore cables.
Warning!
FC/APC and E2000APC are standards for angle-polished connectors and must not be confused
with standard FC/PC and E2000 connectors respectively. The two connector-types are not
interchangeable and mating one with the other will damage both the cable and the module
connectors.
The specification of the FC/APC and E2000APC optical connector is critical to the performance
of the complete fibre optic link. System performance can only be guaranteed with fibre optic
cables and connectors supplied by PPM. FC/APC connectors must be “narrow key width” (see
technical specification).
2.2.2 Connecting and Disconnecting
Before connecting optical fibres to the module or to each other, ensure that the mating connectors are
clean (see below).
2.2.2.1 FC/APC
To connect FC/APC optical connectors, remove the dustcaps and align the white ceramic centre ferrule
on the cable connector with the receptacle. There is a lug on the side of the ferrule, which must match
the gap in the receptacle shroud. When they are aligned, gently push the plug home and finger tighten
the knurled collet nut onto the threaded receptacle. See Figure 1 below.
To disconnect FC/APC connectors, unscrew the knurled collet on the plug and gently withdraw the plug.
Replace the dustcaps on both the receptacle and the cable plug.
