The AXIS TD8902 SFP+ Module LC.SR.X is an SFP+ transceiver (Small Form-Factor Pluggable+) designed to provide an optical fiber network connection for network devices such as switches and routers. The module is suitable for industrial use due to its wide temperature range (between -40 °C and +65 °C) and features a signal loss function that enables network redundancy. It complies with the SFP+ Multisource Agreement (MSA) and can be easily installed at any time on compatible ports without interrupting the online operation of the host devices. Short-wavelength VCSEL laser diodes (850 nm) allow data transmission over distances of up to 400 m using optical fibers (multimode, 50/125 µm). The module has been tested and verified with Axis products such as the AXIS D8208-R Industrial PoE++ Switch. Link-loss function for network redundancy. Through the signal loss function (LOS - Loss of Signal), the system detects a loss of connection.
