A 10GBASE-SR SFP module, also called 10G SFP+ SR, is a 10 Gbps multimode optical transceiver using 850 nm VCSEL laser technology and duplex LC connectors, designed for short-reach fiber links over OM3 and OM4 multimode fiber, typically up to 300–400 meters. As enterprise networks, cloud data. SFP+ stands for “Small Form-Factor Pluggable Plus” and it's a type of hot-pluggable transceiver that supports data rates up to 10 gigabits per second (Gbps). SFP+ is commonly used in high-speed data transmission in data centers, servers, SANs and networking equipment. So, what is the. When it comes to cost-effective 10 Gigabit Ethernet over short to medium distances, the SFP-10G-SR optical transceiver remains a cornerstone technology.
