Note
For hardware specifications, see the
“A.6.2 OC3 IR/STM1SH 1310-8 Card Specifications” section on
page A-29
. See
Table 4-2 on page 4-5
for optical card compatibility.
The OC3 IR/STM1 SH 1310-8 card provides eight intermediate or short range SONET/SDH OC-3 ports
compliant with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE. Each port operates at
155.52 Mbps over a single-mode fiber span. The card supports VT, nonconcatenated (STS-1), or
concatenated (STS-3C) payloads.
Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.
