Optical Card Front Panel Descriptions

Tx Data IN

Tx Data Input allows electrical data signals to be applied to the optical transmitter. This input must be connected to the Tx Data Out port found on the OTS91Tn Transmitter card of the OTS9100 system using the coax cable provided.

Laser Lockout, Remote Interlock

REMOTE INTERLOCK is a bantam plug normally closed connection internally wired in series with the laser lockout key switch. It can be used with additional hardware to disable the laser output.

NOTE: If this connection is used, the ferrite bead provided with the module must be attached to the remote interlock cable for lower emissions and CE mark conformance. Install the bead close to the end of the cable connected to the Optics card.

Laser LOCKOUT is a safety device. The key switch disables the laser output when it is turned to the “open lock” position. The laser output can only be turned on when the key is in the “closed lock” position.

NOTE: The laser output cannot be enabled unless:

The Laser Lockout key switch is set to the “open lock” or on position.

The Remote Interlock is either not used or externally enabled.

The Laser output is software enabled.

1.NOTE: Optical cables use and care. When using the optical cables ensure that the cable is firmly seated in the front panel connector. The optical connectors on the front panel are keyed. If the cable is not inserted into the connector key properly, the connection between cable and front panel will not be complete and so will cause errors in transmission and receiver functions.

2.Always be sure to clean both cable connectors and front panel connectors before installing optical cables. A dirty optical connection can cause errors in transmission and receiver functions.
