10G SFP+ Duplex Transceiver

Come-Star offers a series of high-performance, cost-optimized 10G SFP+ optical modules supporting extended reach up to 40km. Designed for carrier-grade reliability, it integrates:

• DFB laser (1310nm) for single-mode long-haul transmission

• PIN photodiode with TIA (Transimpedance Amplifier) for high-sensitivity reception

• Microcontroller unit for real-time DDM/DOM monitoring (Tx/Rx power, temperature, voltage)

Key Features:
✔ Hot-pluggable SFP+ form factor
✔ Low power consumption (<1.5W typical)
✔ Dual LC fiber interface
✔ Operating temperature: -40°C to +85°C (industrial grade available)
