3.1.2 Console FMB-X-2.5

Card P/N 903-5083-00

The front panel view of the console FMB-X-2.5 is shown in the figure below. Redundant ST fiber connectors

are accessible as straight bushings on the front panel marked "F1" and "F2". An internal fiber switch chooses

one of the fibers for the optical link, either automatically or manually via the front panel toggle switch. Typically

the output power should be greater than -2 dBm at 1550 nm (downlink) and the receive sensitivity at the front

panel should be better than -28 dBm at 1310 nm (uplink).

BLANK OR 10M = GLINK FMB -X

LEDs on the front panel of the remote or console FMB-X-2.5 provide status of video channels, optical link,

and card health per table below.

LED

VIDEO LEDs are green when video sync is detected on each video channel from slot A and

VIDEO

slot B in the rack.

LINK LED is green when a valid optical link is being received and red if no link is present. A

LINK

valid optical link means that the local FMB is receiving valid data frames from the far end card.

FO-RX LED is green when the received optical power is within specified operating range, i.e.

above the minimum sensitivity and below the saturation level. This LED will change to orange

(warning) when the receive power is within roughly 2-3 dB of the receiver failing at low power

or within roughly 1-2 dB of saturating and failing at high power. The LED will change to red

FO-RX

(alarm) when the power level is either too low or too high to provide a reliable optical link,

although in some cases the link will still be functional with a higher than normal bit error rate.

Warning and alarm thresholds are stored in registers in the SFP transceivers. Problems with

optical power should be investigated using the diagnostic software and/or fiber optic power

meters.
