User Manual  

GENERAL:


The OFS 4020 optical fibre switcher allows 5 optical input signals to be switched to a single output.

OFS-4020 cards can be cascaded for expanded operation. Cards can be added sequentially with no user configurations needed.

Rather than having a receiver for each optical path and monitoring or switching the resultant electrical outputs, the OFS 4020 allows a single common optical receiver to monitor multiple optical signals.

When used at the signal transmit end, for example, and used in conjunction with optical splitters, the OFS-4020 ensures that each optical transmitter card is not only transmitting correctly, but is also being fed with the correct signal source.

Likewise, using the OFS-4020 at the receive side allows monitoring of multiple signals coming out of the fibres before being fed into the receive end system.

Local control is provided by front panel pushbutton switches that select and illuminate to indicate the switcher position status.

Simple Network Management Protocol (SNMP) monitoring and control is possible when operated in a frame fitted with SNMP capability.

The OFS-4020 is designed to fit IRT's 1000 series 1RU or 4000 series 3RU Eurocard frames.
