The XFP-10G-SR is a 10Gbps optical transceiver designed for short-range communication. It supports multi-mode fiber (MMF) transmission with a reach of up to 300 meters over OM3 fiber and operates at a wavelength of 850nm. The module uses an XFP (10 Gigabit Small Form Factor Pluggable) interface and is commonly used in applications such as high-speed data transmission in data centers and telecom networks. It is compatible with various networking equipment and is typically used for Ethernet, SONET/SDH, and other optical networks.
