Description

The CFP-100G-LR4 is a hot-swappable 100 Gigabit Ethernet CFP optical transceiver from the Cisco 100GBASE CFP module range. It carries 100G over standard single-mode fibre (G.652) at distances up to 10 km, using four LAN-WDM wavelengths in the 1310 nm band. It suits data centre networking, enterprise core aggregation and service provider transport links.

The module is a 100GBASE-LR4 design that works to IEEE 802.3ba and the CFP MSA. The four lanes sit at 1295.6, 1300.1, 1304.6 and 1309.1 nm. Transmit power runs from -4.3 to 4.5 dBm per lane, and receive power from -10.6 to 4.5 dBm per lane. Digital Optical Monitoring is supported. Maximum power draw is 24 W, supplied by the host CFP port, and the operating temperature range is 0 to 70 C. The connector is dual SC/PC. Within the CFP family, this is the 10 km single-mode option, between the 100 m multimode CFP-100G-SR10 and the 40 km CFP-100G-ER4.

No licence or subscription is required by the module itself. It is supported on Cisco switches and routers with CFP ports, such as ASR 9000 100GE line cards. Use patch cords with PC or UPC connectors only, as APC connectors are not supported.

FAQs

Q: Does this transceiver need a licence or subscription?
A: No. The module itself requires no licence or subscription. It is powered from the host CFP port.

Q: What fibre and connectors does it use?
A: It runs over standard single-mode fibre (G.652) with dual SC/PC connectors. Use patch cords with PC or UPC connectors only, as APC connectors are not supported.

Q: Which Cisco platforms support the CFP-100G-LR4?
A: It is supported on Cisco switches and routers with CFP ports, for example ASR 9000 100GE line cards. Check the Cisco 100-Gigabit Ethernet Transceiver Modules Compatibility Matrix for your exact platform.

Q: How does it differ from the CFP-100G-ER4 and CFP-100G-SR10?
A: The CFP-100G-LR4 reaches 10 km on single-mode fibre. The CFP-100G-ER4 reaches 40 km on single-mode fibre, while the CFP-100G-SR10 is a multimode module for 100 m or 150 m links.

Q: How much power does it draw?
A: Maximum power consumption is 24 W per module, drawn from the host CFP port. Operating temperature range is 0 to 70 C.
