This high-performance 1000BASE-ZX SFP transceiver is engineered for long-distance single-mode fiber applications, delivering reliable connectivity up to 80 kilometers. With a robust 21 dB optical link budget, it ensures stable data transmission across extended networks.

The module supports full DDM (Digital Diagnostics Monitoring), enabling real-time monitoring of transceiver status with most SNMP network management tools. This allows for proactive network maintenance and troubleshooting.

Fully compatible with Cisco switches and MSA (uncoded) standards, this transceiver serves as a direct replacement for Cisco's GLC-ZX-SM module, offering exceptional value without compromising performance or reliability.

Important Installation Note: When fiber-optic cable span loss is less than 8 dB, insert a 10-dB inline optical attenuator between the cable plant and the receiving port at each end of the link to protect the receiver.
