Enhanced FEC Capability
An important feature of the 10-Gbps Full-Band Tunable Enhanced Transponder Card is the
availability to configure the Forward Error Correction (FEC) in three modes: NO FEC, FEC, and E-
FEC. The output bit rate will depend by the bit rate of the incoming signal but the digital wrapper
will be always as defined in G.709.
●
10.70923 Gbps in case of OC-192/STM-64/10 Gigabit Ethernet WAN
●
11.095 Gbps in case of 10 Gigabit Ethernet LAN PHY (over-clocking mode)
●
11.3168 Gbps in case of 10 Gigabit Fibre Channel (over-clocking mode)
Error coding performance can be provisioned:
●
NO FEC: no Forward Error Correction
●
FEC: standard G.975 Reed-Salomon algorithm
●
E-FEC: standard G.975.1 two orthogonally concatenated BCH super FEC code. This FEC
scheme contains three parameterizations of the same scheme of two orthogonally
interleaved block codes (BCH). The constructed code is decoded iteratively, to achieve the
expected performance.
Protocol Transparency
The 10-Gbps Full-Band Tunable Transponder Card provides transparent wavelength services on
the Cisco ONS 15454 platform. For SONET- or SDH-based client payloads, when provisioned in
transparent operating mode, the card will pass all of the SONET/SDH overhead bytes
transparently. The card monitors important SONET/SDH overhead bytes, such as B1 (section BIP-
8) and J0 (section trace), to allow fault isolation and performance monitoring capabilities.
Termination of the line data communications channel (LDCC) is user-provisionable, to enable the
platform processor to route the DCC information for intracarrier networking or to allow the DCC
information to be transported untouched, via the digital wrapper’s general communications channel
(GCC), for intercarrier networking. For 10 Gigabit Ethernet and OC-192/STM-64 payloads, digital
wrapper technology (G.709) is used to add a management wrapper to the service, allowing the
transponder card to transparently forward the payload while enabling performance metrics to be
derived to ensure circuit service quality.
The transponder card is transparent to the embedded payload and does not access the Cisco
ONS 15454 platform’s cross-connect. It can carry any type of concatenated SONET/SDH payloads
(STS-Nc or VC-4-Mc); nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, or VT1.5
basis; and 10 Gigabit Ethernet LAN or WAN PHY payloads.
Wavelength Tunability
The 10-Gbps Full-Band Tunable transponder cards operate on the 50-GHz ITU grid and are
tunable across full-band 50-GHz channels per card (one for C and one for L band). The
incorporation of tunability into the 10-Gbps transponder cards reduces the customer’s inventory
required to cover all of the wavelengths for deployment and spares. Tunability is software-
provisionable.
Flexible Protection Mechanisms
The 10-Gbps Full-Band Tunable Transponder Card provides flexible protection capabilities for both
client and DWDM line interfaces, enabling support for numerous network configurations required
to deliver the various service-level agreements (SLAs) for customer applications (Table 1).
