1.25G SFP ZX Optical Transceiver Module 1550nm 80km Single Mode Fiber LC Connector Gigabit Ethernet Optical Module

Technical specifications

The 1.25G SFP ZX Optical Transceiver Module is a high-performance Gigabit optical transceiver designed for long-distance fiber optic communication. Operating at a 1.25Gbps data rate, it utilizes a 1550nm DFB laser transmitter and supports transmission distances of up to 80km over single mode fiber (SMF).

Built in a standard hot-pluggable SFP form factor, the module features a duplex LC optical interface and delivers reliable, stable, and high-speed data transmission. It is fully compatible with Gigabit Ethernet equipment such as switches, routers, OLTs, media converters, and enterprise network devices.

Designed to meet IEEE 802.3z 1000BASE-ZX and SFP MSA standards, this transceiver offers low power consumption, excellent optical performance, and optional Digital Diagnostic Monitoring (DDM/DOM) for real-time operating status monitoring.
