A 1.25G SFP (Small Form-factor Pluggable) module, SM (Single Mode), Single Fiber, 60KM, 1550/1310, LC Connector, is designed for efficient and reliable data transmission over single-mode fiber optic networks. It supports data rates up to 1.25 Gbps and is optimized for medium to long-distance communication, capable of reaching distances of up to 60 kilometers. This module utilizes a single fiber strand for both transmitting (1550 nm) and receiving (1310 nm), which helps reduce deployment costs and complexity. The LC connector ensures secure and low-loss connectivity, making it suitable for applications such as telecommunications networks, ISP backbone links, and enterprise data centers where extended reach and high-speed data transmission are essential.
