Description

This is a hot-swappable 40 Gigabit Ethernet CFP optical transceiver that carries 40GBASE-LR4 over four 1310 nm wavelengths on standard G.652 single-mode fibre, up to 10 km. It also supports the OTU3 C4S1-2D1 standard, so a single module can serve both Ethernet and OTN links.

The four lanes sit at 1271, 1291, 1311 and 1331 nm, and the multiplexing and demultiplexing of those wavelengths is handled inside the module. Transmit power for 40GBASE-LR4 is from -7 dBm to 2.3 dBm per lane, and receive power is from -13.7 dBm to 2.3 dBm per lane. Digital optical monitoring is supported, power draw is up to 8 W per port, and the module operates from 0 to 70 C. The connector is dual SC/PC, and patch cords with APC connectors are not supported.

It is intended for 40 Gigabit Ethernet links of up to 10 km in the core and distribution layers of data centre, enterprise and service provider networks. It fits 40 Gigabit Ethernet CFP ports on Cisco switches and routers, and the Cisco 40 Gigabit Ethernet Transceiver Modules Compatibility Matrix lists the exact supported platforms.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does this transceiver need a licence or software subscription?
A: No licence or subscription is associated with this module. It is powered by the host CFP port and needs no external supply.

Q: What fibre and connector does it use?
A: It uses standard G.652 single-mode fibre with a dual SC/PC connector, for links up to 10 km. Patch cords with APC connectors are not supported.

Q: How much power does it draw from the host port?
A: It draws up to 8 W per CFP port, supplied by the host, with no external power required.

Q: Which devices does it work with?
A: It fits 40 Gigabit Ethernet CFP ports on Cisco switches and routers. Check the Cisco 40 Gigabit Ethernet Transceiver Modules Compatibility Matrix for the exact supported platforms.

Q: Can it be used for both Ethernet and OTN links?
A: Yes. It supports both 40GBASE-LR4 and the OTU3 C4S1-2D1 standard, so it can be used in Ethernet and OTN links.
