The OC48 IR/STM16 SH AS 1310 card provides one intermediate-range, ITU-T G.707- and
G.957-compliant, SDH STM-16 port per card. The interface operates at 2.488 Gbps over a single-mode
fiber span. The card supports concatenated or nonconcatenated payloads at STM-1, STM-4, or STM-16
signal levels on a per VC-4 basis.
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.
