Any new features that are available as part of this software release are not enabled for this card.
Note
The OC192 LR/STM64 LH 1550 card provides one long-range SONET/SDH OC-192 port compliant
with ITU-T G.707, ITU-T G.691, ITU-T G.957, and Telcordia GR-253-CORE (except minimum and
maximum transmit power, and minimum receive power). The card port operates at 9.95328 Gbps over
unamplified distances up to 80 km (50 miles) with different types of fiber such as C-SMF or dispersion
compensated fiber limited by loss and/or dispersion. The card supports VT, nonconcatenated (STS-1),
or concatenated payloads.
There are two versions of the OC192 LR/STM64 LH 1550. The earliest version has the product ID
15454-OC192LR1550, and the latest card's product ID is 15454-OC192-LR2. These cards have slight
specification differences that are noted throughout this description.
The laser is on when the optical card is booted. The port does not have to be in service for the laser

OC192 IR/STM64 SH 1550 Card-Level Indicators
Description
The red FAIL LED indicates that the card's processor is not ready. This LED
is on during reset. The FAIL LED flashes during the boot process. 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 one or more of the card's ports. The amber SF LED is also
on if the transmit and receive fibers are incorrectly connected. If the fibers
are properly connected and the link is working, the light turns off.
