SFP Module

We offer a wide range of SFP Module solutions – from short‑reach multimode to ultra‑long‑haul single‑mode. This article focuses on our 1.25G SFP 1550nm 80km Transceiver, designed for links that stretch across metro or access networks. For other models (e.g., 850nm, 1310nm, or different reaches), please browse our website or contact our sales team.

• Data Rate: Up to 1.25Gb/s – ideal for 1000Base‑Ethernet and 1× Fiber Channel.
• Transmission Distance: Up to 80km over standard 9/125μm single‑mode fiber (SMF).
• Optical Components: 1550nm DFB laser transmitter + PIN receiver for stable long‑haul performance.
• Connector: Duplex LC – compatible with existing single‑mode cabling.
• Power Supply: Single +3.3V with typical dissipation below 1.5W.
• Hot‑Pluggable: Standard SFP footprint, no need to power down equipment.
• Diagnostics: SFF‑8472 monitoring interface for real‑time DDM (temperature, voltage, bias, Rx power).
• Temperature Options: Commercial (0~70°C), extended (-5~85°C), and industrial (-40~85°C).
• Compliance: RoHS, lead‑free.

• Metro and access networks
• 1.25Gb/s 1000Base‑Ethernet

This 1.25G SFP Module is built for service providers and enterprise users who need to connect two far‑end sites without signal regeneration. The 1550nm DFB laser ensures low dispersion over long spans, while the low power budget (<1.5W) keeps your equipment room cool. Every unit is fully tested before shipping and backed by our quality system (ISO 9001, RoHS, REACH, CE). Whether you are extending a campus backbone or building a metro ring, this SFP Module delivers reliable, plug‑and‑play performance at 80km.
