The Cisco X2-10GB-LX4 is a 10Gbps transceiver module designed for multimode fiber connections using four wavelengths on a single strand. It operates over an 850nm to 1355nm range, reaching up to 300 meters with OM3 fiber.

This X2 form factor module supports SC duplex connectors and complies with IEEE 802.3ae standards for reliable data transmission in high-speed networks. With hot-swappable capability, it allows network expansion without service disruption. A power consumption of approximately 4W aids efficient operation while maintaining performance across supported distances.

The digital optical monitoring (DOM) function provides real-time diagnostics such as output power levels and temperature readings for better troubleshooting and maintenance tracking within the network infrastructure‌.
