Trinix Fiber Boards Overview
WARNING Fiber-optic connectors need to be cleaned every time they are mated and
un-mated; it is essential that fiber-optic users develop the necessary dis-
cipline to always clean the connectors before they are mated.
Follow these steps when cleaning fiber-optic connectors:
• When cleaning the connector sections, include the tips and sides of fer-
rules, the interior walls of alignment sleeves, and the interior and exte-
rior of connector shells.
• For plugs, the interior surfaces of alignment sleeves and the tips of
ferrules are to be cleaned with a cleaning stick treated with the
appropriate fluid. (Cleaning sticks with a slender design are avail-
able that allow alignment sleeves to be cleaned without having to
detach them.)
• For jacks, it is important to clean both the tips and sides of the com-
pletely protruding ferrules.
• Clean both the insides and outsides of the male and female connector,
as the shells tend to attract dust and metal particles.
• The fiber end face and ferrule must be absolutely clean before it is
inserted into a transmitter or receiver.
• Mate the connector immediately! Do not let the connector collect dust
before connecting.
• Air can be used to remove lint or loose dust from the port of a trans-
mitter or receiver to be mated with the connector. Never insert any
liquid into the ports.
The Trinix Fiber modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser
-
viced in the field unless otherwise directed by Customer Service.
Power-up Diagnostics Failure
If the module has not passed self-diagnostics, do not attempt to trouble-
shoot. Return the unit to Grass Valley.
Troubleshooting
Electronic Circuit Breaker: The electronic circuit breaker works during a
fault condition or an over-current that stops the module.
Remove the module and replace it in the frame. If the problem persists,
please refer to the Grass Valley Customer Service.
Module Repair: If the module is still not operating correctly, replace it with
a known good spare and return the faulty module to a designated Grass
Valley repair depot. Call your Grass Valley representative for depot loca
