Yokogawa LS38-C3S-TI-N-GD Fiber Optic Transceiver Module

Product Overview

The LS38-C3S-TI-N-GD (LS38-C3S-TI-N-GD) is a high-performance, small form-factor pluggable (SFP) optical transceiver engineered for Yokogawa industrial networking and control systems. This module facilitates high-speed data transmission over single-mode fiber (SMF), supporting rates between 1063 and 1250 Mb/s. Utilizing a 1310 nm Fabry-Perot (FP) laser, it is capable of bridging distances up to 10 km. Designed for mission-critical infrastructure, the module operates across an extended industrial temperature range, ensuring network stability in environments subject to thermal extremes.
