PRODUCT PRESENTATION

The JFOPT QSFP28 100G PSM4 2km MPO 8/12 is a high-performance, four-channel pluggable parallel fiber-optic transceiver designed for 100G Ethernet applications. This full-duplex module features four independent transmit and receive channels, each supporting 26Gbps, delivering a total aggregate data rate of 104Gbps over distances of up to 2km on single-mode fiber.Equipped with a 1310nm DFB laser array, the transceiver connects via an MPO/MTP optical fiber ribbon cable. As a parallel transceiver, the QSFP28 PSM4 enhances port density and reduces total system costs, making it an efficient solution for high-speed networking environments.
