400G-QSFP-DD-LR4 2km Optical Module RTXM290-342 CWDM Transceiver EML Original
400G QSFP-DD LR4 is a type of transceiver module that is used in high-speed data communications networks. QSFP-DD stands for Quad Small Form-factor Pluggable Double Density and LR4 stands for Long Range 4.
This transceiver module can transmit data at a rate of 400 Gigabits per second (Gbps) over a distance of up to 10 kilometers. The LR4 designation indicates that it uses four channels of 100Gbps each, with each channel transmitting data over a different wavelength (1310nm, 1295nm, 1275nm, and 1255nm) in the optical fiber.
This type of transceiver module is commonly used in data centers and high-performance computing applications where high-speed and long-distance data transmission is required. It is typically used to connect switches, routers, and other networking equipment.
