Extreme Networks 10320 Compatible 40GBASE-LR4 QSFP+ 40G 1310nm 10km DOM Duplex LC/UPC SMF Ethernet Optical Transceiver Module
The 40G-QSFP-LR4 is a high-performance transceiver module designed for long-range optical communication applications, supporting transmission distances of up to 10 kilometers. It complies with the IEEE P802.3ba 40GBASE-LR4 standard, ensuring reliable and efficient data transmission. The module converts four input channels of 10Gb/s electrical data into four CWDM optical signals, which are then multiplexed into a single channel for 40Gb/s optical transmission. On the receiver side, it de-multiplexes a 40Gb/s optical input into four CWDM channels and converts them back into four channels of electrical data.

Our core switches from Huawei and Arista detected the optics instantly. Compatibility is on par with the big-name brands, but at a fraction of the cost.
