The unit has an FC/APC angle polished optical connector for very
high optical return loss performance. The units are specified into
single mode fiber i.e. 9/125 micron core diameter. Full performance is
specified only for low return loss optical plant - meaning that the
fiber must be fusion spliced and all connections or splices must have
a return loss greater than -60 dB. With these guidelines in mind, link
lengths beyond 20 kilometers (DFB based products) can be achieved
with high performance. Specific performance and/or design
assistance is available by request from Foxcom.
If there is low/no signal or noisy signal at a Foxcom module, the
connector should be cleaned. Dirt on the inside connector tip can
impair the flow of light causing problems in signal transmission.
Foxcom modules are sealed but dirt can occasionally enter during
installation and alignment.
The input and output optical ports of all Foxcom equipment are
known in the fiber optic world as bulkhead ports. Foxcom uses
FC/APC connectors.
The following materials are representative of the types of cleaning
materials that should be used for cleaning the fiber optic ports and
connectors. They are available from several suppliers.
Wiping clothes should be made of lint free alcohol free nonabrasive
materials. Swabs should have a tightly wrapped tip and be talcum-
free. For removing dust from receptacles, a canned compressed gas is
recommended. Do not use commercial compressed air because of risk
of contamination.
