The GLC-ZX-SMD is a 1000BASE-ZX Small Form-factor Pluggable (SFP) transceiver module designed for Long-Reach Single-Mode Fiber (SMF) communication. It enables high-speed network connectivity, typically supporting Gigabit Ethernet (1.25Gbps) data rates. The module operates at a wavelength of 1550nm and supports transmission spans of up to approximately 70 km, though compatible versions may support up to 80 km depending on link loss and fiber quality. It uses an LC duplex connector and often includes Digital Optical Monitoring (DOM) support for real-time diagnostics like optical power, temperature, and voltage monitoring. It is engineered for demanding network environments such as data centers and enterprise networks. A 10-dB inline optical attenuator may be required for links shorter than 8 dB loss to prevent receiver overload.
