Huawei's OSX040N01 is a high-performance SFP+ module designed for 10G Ethernet applications. The LC interface ensures easy and secure plug-and-play. If the SFP-10G-ER-1310 is connected to a 10Gbase-ER standard optical module (1550nm, 10GE, 40km), the maximum transmission distance is only 20km due to different specifications such as wavelength and receiving sensitivity. Single-fiber bidirectional (BIDI) optical modules must be used in pairs. Operating at a 1550nm wavelength with a reach of up to 40km, this optical transceiver is ideal for carrier, data center, and enterprise aggregation scenarios. A 10GE optical module (SFP+) is connected to two LC optical fibers to provide one GE channel. Apply to Huawei SX700, SX300 series campus switch CE series data center switch.
