A.6.13 OC192 LR/STM64 LH ITU 15xx.xx Card Specifications
The OC192 LR/STM64 LH ITU 15xx.xx card has the following specifications:
• Line
– Bit rate: 9.95328 Gbps
– Code: Scrambled NRZ
– Fiber: 1550-nm single-mode
– Maximum chromatic dispersion allowance:
In deployments with a dispersion compensating unit (DCU): +/– 1000 ps/nm, with optical
signal-to-noise ratio (OSNR) of 19 dB (0.5 nm resolution bandwidth [RBW])
In deployments without a DCU: +/– 1200 ps/nm, with OSNR of 23 dB (0.5 nm RBW)
– Loopback modes: Terminal and facility
Note You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the
OC192 LR/STM64 LH 15xx.xx card in a loopback. Do not use fiber loopbacks with the
OC192 LR/STM64 LH 15xx.xx card. Using fiber loopbacks causes irreparable damage to
this card.
