10G X2 850nm 300m

The X2-10GB-SR Compatible 10GBASE-SR X2 Transceiver Module is a high-performance solution for 10 Gbit/s data transmission in enterprise networks. It uses an 850nm VCSEL to enable reliable 300-meter connectivity over multimode fiber (MMF) with a duplex SC connector. This X2 module is ideal for short-reach, high-bandwidth applications like data center links. The module features a 4×3.125 Gbps XAUI interface and integrated SERDES (Serializer/Deserializer) for efficient data conversion. Compliant with XENPAK MSA 3.0, it ensures interoperability and robust performance in demanding environments. Its design minimizes signal loss, supporting seamless 10 Gigabit Ethernet connectivity. Digital diagnostics via a 2-wire serial interface monitor optical power, temperature, and voltage in real time, aiding network management. The X2-10GB-SR module offers a cost-effective, reliable option for upgrading 10 Gigabit Ethernet infrastructure with enhanced monitoring capabilities.
