4.17 4.16.1 OC192 LR/STM64 LH 1550 Card-Level Indicators
The card port features a 1550-nm laser and contains a transmit and receive connector (labeled) on the
card faceplate.The card uses a dual SC connector for optical cable termination. The card supports 1+1
unidirectional and bidirectional facility protection. It also supports 1:1 protection in four-fiber BLSR
applications where both span switching and ring switching might occur.
The OC192 LR/STM64 LH 1550 card detects SF, LOS, or LOF conditions on the optical facility. The
card also counts section and line BIT errors from B1 and B2 byte registers in the section and line
overhead.

4.16.2 OC192 LR/STM64 LH 1550 Port-Level Indicators
You can find the status of the OC192 LR/STM64 LH 1550 card port by using the LCD screen on the
ONS 15454 fan-tray assembly. Use the LCD to view the status of the port or card slot; the screen displays
the number and severity of alarms for a given port or slot.
The optical output power of the OC192 LR/STM64 LH 1550 (+4 dBm to +7 dBm) is 6 dB lower than in
Note
L-64.2b of the 10/2000 prepublished unedited version of ITU-T G.691 (+10 dBm to +13 dBm). However,
the total attenuation range of the optical path, 22 to 16 dB, is maintained by the optical receiver
sensitivity range of the OC192 LR/STM64 LH 1550 (–7 dBm to –24 dBm). This sensitivity range
outperforms the specification in L-64.2b of the 10/2000 prepublished unedited version of ITU-T G.691.
The resulting link budget of the card is 26 dBm.

describes the three card-level LEDs on the OC192 LR/STM64 LH 1550 card.
OC192 LR/STM64 LH 1550 Card-Level Indicators
Description
The red FAIL LED indicates that the card's processor is not ready. Replace
the card if the red FAIL LED persists.
If the ACT/STBY LED is green, the card is operational and ready to carry
traffic. If the ACT/STBY LED is amber, the card is operational and in
standby (protect) mode or is part of an active ring switch (BLSR).
The amber SF LED indicates a signal failure or condition such as LOS, LOF,
or high BERs on the card's port. The amber SF LED is also on if the transmit
and receive fibers are incorrectly connected. If the fibers are properly
connected, the light turns off.
