Note
For hardware specifications, see the
“A.6.1 OC3 IR 4/STM1 SH 1310 Card Specifications” section on
page A-28
. See
Table 4-2 on page 4-5
for optical card compatibility.
The OC3 IR 4/STM1 SH 1310 card provides four 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 Virtual Tributary (VT), nonconcatenated
(STS-1), or concatenated (STS-1 or STS-3c) payloads.
Figure 4-1
shows the OC3 IR 4/STM1 SH 1310
faceplate and a block diagram of the card.
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.
