Description

The Sopto SPT-P13TG-LR(S) series provides 10GBASE-LR/LW compliant optical transceivers for distances up to 10 km or 20 km over single-mode fiber. Featuring a 1310 nm DFB laser transmitter and a PIN photodiode receiver, these modules deliver high-performance, full-duplex transmission with low power consumption.

Designed to SFP+ MSA, IEEE 802.3ae, SFF-8431, and SFF-8472 standards, the modules include digital diagnostics (DDM) for real-time monitoring of operating conditions (temperature, voltage, TX/RX power). The hot-pluggable LC duplex interface makes them easy to deploy and maintain in live networks.

Available in standard commercial grade (0 to 70 °C) and industrial grade (–40 to +85 °C) versions, the SPT-P13TG-LR(S) series is well-suited for enterprise networks, ISP backbones, and high-density data centers requiring reliable long-haul 10G links.

Application

Enterprise networks, ISP backbone, Data centers, Metro Ethernet, FTTH backhaul
