Transponder Line Cards
The protocol-transparent and bit-rate transparent transponde r li ne c ard co nverts a singl e cl ie nt sign al
into an ITU wavelength, or channel.The Cisco ONS 15530 shelf holds up to four transponder line cards,
one for each wavelength supported by the OADM modules.
The Cisco ONS15530 s uppo rt s fou r ty pe s of si n gle clie nt i nte rface tran spon der l ine ca rds :
•SM (si ngle- mode) n onspl itter
•SM splitter
•MM (multimode) nonsplitter
•MM splitter
Both types of SM transponder line cards accept SMc lient signal s on the 1310-nm wavelength through
an SC connector and support client signal clock rates ranging f rom 16Mbps to 2.5 Gbps. Bothtyp es of
MM transponder line cards accept SM an d MM client signals on the 1310-nm wavelength through an
SC connector and support client signal clock rates ranging from 16 Mbps to622 Mbps.
The transponder line cards are hot pluggable, permitting in-service upgrades and replacement.
All client signals on the transponders are supported in 3R (reshape, retime, retransmit) mode, regardless
of protocol encapsulation type. The following protocol encapsulation ty pes a re su ppo rte d in 3R mo de
plus protocol monitoring:
•ESCON (200 Mbps) SM and MM
•Fibre Channel (1 Gbps) SM
•FICON (Fiber Connection) (800 Mbps) SM
•Gigabit Ethernet (1000 Mbps) SM
•SDH (Synchronous Digital Hierarchy) STM-1 SM and MM
•SDH STM-4 SM and MM
•SDH STM-16 SM
•SONET OC-3 SM and MM
•SONET OC-12 SM and MM
•SONET OC-48 SM
•ISC (InterSystem Channel) links compatibility mode
The following protocol encapsulation types are supported in 3R mode wi thou t pr otoc ol m on ito ring:
•Fast Ethernet SM
•FDDI SM
•Fibre Channel (2 Gbps) SM
•ISC peer mode SM
•Sysplex CLO (control link oscillator) MM (8 Mbps)
•Sysplex ETR (external timer reference) MM (8Mbps)
The client interfaces also support the OFC (open fiber control) safety protocol for Fibre Channel, ISC
compatibility mode, and FICON. Client-side interfaces are protocol transparent and can accept signals
at specific rates between 16 Mbps and 2.5 Gbps .
