Operating at 1310nm with STM16 capabilities, this module offers an impressive output power range from -2dBm to -3dBm and a receiver sensitivity up to 29dBm. Engineered for long-distance communication, it supports single-mode fiber transmissions over distances up to 40km with. 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. Every LE2MGSC40DE0 is environmentally tested in its specific port/platform prior to shipping to ensure that they are in perfect.
