Transponder Card Versions
Two versions of the Cisco 40-Gbps Full-Band Tunable CP-DQPSK Transponder Cards are offered to support
different application requirements:
●
An extended performance version offering full performances targeting ULH application, where the network
is optimized for CP-DQPSK transmission (no 10-Gbps channels and Dispersion Compensation Units
[DCUs])
●
A metro edge performance version with differential mode only (CP-DQPSK), cost-optimized for metro
application and 10-Gbps installed networks
Protocol Transparency and Card Configuration
The Cisco 40-Gbps Full-Band Tuneable CP-DQPSK Transponder can deliver transparently any 40-Gbps services
for cost-effective, point-to-point networking for the Cisco ONS 15454 platform.
The card can be provisioned in two operational modes: OTU3 or OTU3e.
In OTU3 mode, the card can transparently transport STM-256, OC-768 40 GbE WAN-PHY signals. In OTU3e
mode, to the card can transparently transport a 40 GbE LAN PHY Constant Bit Rate (CBR) signal on a serial
interface, as shown in Table 1.

The card can also process provisionable SONET/SDH overhead bytes. It is possible to pass the bytes
transparently or to terminate the line and section overhead. In transparent mode, client terminal equipment
interconnected over a transponder-based circuit can communicate over the section (or multiplexer section) data
communications channel (SDCC/MSDCC), can signal 1+1 and bidirectional line switched ring or multiplex section-
shared protection ring (BLSR/MS-SPR) protection switching using the K1 and K2 bytes, and can support
provisionable section trace capabilities over the J0 byte.
In addition, the transponder circuit, whether provisioned in transparent or terminating mode, can support client
circuits based on unidirectional-path switched ring (UPSR) or subnetwork connection protection (SNCP). The
transponder card is transparent to the embedded payload and does not access the Cisco ONS 15454 platform’s
transponder card is transparent to the embedded payload and does not access the Cisco ONS 15454 platform’s
cross-connection. It can carry any type of concatenated SONET/SDH payloads (STS-Nc or VC-4-Mc), or
nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, or VT1.5 basis.
Wavelength Tuneability
The transponder card operates on the 50-GHz ITU grid and it is tuneable across the full C-band, on 50-GHz
channels. Tune
ability reduces the customer’s inventory required to cover all of the wavelengths for deployment and
spares. Tuneability is software-provisionable.
