AXIS TD8902 SFP+ Module LC.SR.X is an enhanced small form-factor pluggable (SFP+) transceiver that supplies network devices, such as a switches or routers, with a fiber optic network connection. It is industrial grade with a wide temperature range (between -40 °C to 65°C), and it includes loss of signal feature that enable network redundancy. Complying with SFP+ Multisource Agreement (MSA), it is easy to install into compliant ports at any time without interrupting the online operation of the host equipment. Short wavelength (850 nm) VCSEL laser diodes enable data transmission up to 400 m on a multimode 50/125 ?m optical fiber. The module is tested and verified with Axis products such as AXIS D8208-R Industrial PoE++ Switch. Link-loss feature for network redundancy The loss of signal (LOS) feature allows for the system to recognize a lost connection between a specific hardware (For example, AXIS Network Cameras) and the host. For optimized network redundancy, AXIS TD8902 signals the hardware in case of a lost connection or unusable connection for network traffic. This allows for the hardware to redirect the network traffic through a fallback connection, for example via RJ45.
