Cisco CFP-40G-LR4 Transceiver Module – 40GBASE-LR4 / OTU3 1310nm 10km
The Cisco CFP-40G-LR4 is a multirate CFP optical transceiver designed for high-capacity 40 Gigabit Ethernet and optical transport applications. It supports both IEEE 40GBASE-LR4 and OTU3 C4S1-2D1 standards, providing flexible 40G connectivity over single-mode fiber.
The module operates using four CWDM optical wavelengths centered at 1271nm, 1291nm, 1311nm, and 1331nm. The four wavelengths are multiplexed and demultiplexed within the module, enabling a single duplex fiber pair to carry the 40Gbps signal over distances of up to 10km.

Compatibility
The Cisco CFP-40G-LR4 is designed for compatible Cisco 40 Gigabit Ethernet CFP ports and optical networking platforms. Cisco documentation identifies the module for compatible switches, routers, and optical transport equipment supporting 40GBASE-LR4 and OTU3 interfaces.
The module uses a duplex SC/PC optical interface and G.652 single-mode fiber. Cisco specifies that PC or UPC polished connectors are supported, while APC polished connectors are not supported for these CFP optical interfaces.
Important: The CFP-40G-LR4 should not be confused with the Cisco QSFP-40G-LR4 or QSFP-40G-LR4-S. The requested product is a full-size CFP module with duplex SC connectivity and multirate 40GbE/OTU3 support.
