Sopto SPT-P85TG-SR — 10G SFP+ Optical Transceiver

The Sopto SPT-P85TG-SR is a 10Gbps SFP+ optical transceiver for short-reach multimode fiber links. Operating at 850 nm with LC duplex connectors, it supports transmission distances up to 300 m. Fully compliant with 10GBASE-SR, hot-pluggable, and featuring digital diagnostics (DDM), it is ideal for data centers, enterprise LANs, and high-density switch interconnects.

Description

The Sopto SPT-P85TG-SR is a high-performance 10G SFP+ optical module engineered for short-range applications. Operating at 850 nm using a VCSEL laser transmitter and PIN receiver, it supports 10Gbps full-duplex Ethernet over multimode fiber (MMF) with link lengths up to 300 meters on OM3 fiber.

This module is fully compliant with IEEE 802.3ae 10GBASE-SR, SFP+ MSA, SFF-8431, and SFF-8472, ensuring broad interoperability with switches, routers, and network interface cards. Built-in digital diagnostics (DDM) provide real-time monitoring of parameters such as temperature, voltage, and optical power, improving reliability and simplifying troubleshooting.

Compact and hot-pluggable with a duplex LC connector, the SPT-P85TG-SR offers energy-efficient performance (<1 W typical) and EMI-shielded housing. It is widely used in data centers, enterprise networks, and storage area networks (SANs) where cost-effective short-haul 10G connectivity is required.
