The Cisco NCS 1004 OTN-XPonder Line Card embeds a flexible core FPGA (Field Programmable Gate Array), which allows for support of multiple applications like Muxponder, Transponder, and OTN-Switch, pending future roadmap releases.
The line card features a large variety of different pluggable interfaces:
- 4x DD-QSFP56/QSFP28/QSFP+ ports (two of which can be used as a QSFP-DD trunk as an alternative to CFP2 DCO WDM) for 400GE, 100GE/OTU4, 32G/16G FC, or 10GE/OTU2/OTU2e clients
- 8x QSFP-28/QSFP+ ports for 100G, 32G/16G FC, or 10GE/OTU2/OTU2e clients
- 2x CFP2 DCO WDM for high-performance (with optional encryption) trunks (to be used instead of the DD-QSFP trunk)
Different FPGA images will support different card configuration, pending SW roadmap availability.
Because of this, the line card is ready to support the following configuration:
"Grey Muxponder," available in Cisco IOS®XR Release 7.2.1 and later.
10x10G signals multiplexed onto an OTU4 Grey QSFP28. Up to two slices of the 10x10G Muxponder can be configured on the OTN Xponder line card.
Two major use cases are addressed by such an application:
- Provide 10G fan out option to 1.2T Muxponder line card. In one NCS1004 chassis can be placed a 1x1.2T Muxponder configured (for example) with a 600G trunk multiplexing a 6xOTU4 coming from a 3xOTN-Xponder line card supporting 20x10G each. This configuration is providing 60x10G over a single 600G lambda in 2RU.
- Provide 10G to OTU4 demarcation for a customer who requires an OTN "grey" signal hands off to a third-party network. Up to a 4xOTN-Xponder can be placed in a single NCS 1004 chassis to support 80x10G over 8xOTU4 hands off.
In Cisco IOS® XR Release 7.3.1 OTN-XP will be able to support 400G wavelengths with new CFP2 DCO at 400G on the following configurations:
- 2x400GE TXPs over 2x400G 16-QAM WDM lambdas. Supported 400G client type will be 400GE.
- 2x4x100G MXPs over 2x400G 16-QAM WDM lambdas. Supported 100G client types will be 100GE and OTU4.
- 1x400G TXPs + 1x4x100GE/OTU4 MXP over 2x400G WDM lambdas.
In future roadmap releases, OTN-XP will be able to support wavelengths at 200G or 300G as well as additional client rates:
- 40x10G over 1x400G WDM lambda. Supported 10G client type will be 10GE, OTU2 and OTU2e
- 2x2x100G MXPs over 2x 200G QPSK WDM lambdas. Supported 100G client type will be 100GE and OTU4
- 2x3x100GE/OTU4 over 2x1x 300G 8-QAM WDM lambdas
- Hybrid configuration with 10x10GE/OTU2/OTU2e + 3x100GE/OTU4 over a single 400G 16-QAM WDM lambda
- Inverse Multiplexing of 400GE over 2x200G QPSK lambdas
