STC-50GS – 50G QSFP28 10km Transceiver

50Gbps QSFP28 single-mode optical transceiver for long-reach links – up to 10km

Product Overview

The STC-50GS is a high-performance 50G QSFP28 LR transceiver designed for long-distance transmission over single-mode fiber (SMF) using a duplex LC connector. It supports 50GBASE-LR links over distances of up to 10 kilometers, operating at a center wavelength around 1311nm. The module is fully compliant with IEEE 802.3cd, SFF-8636, and SFF-8679 standards. With low power consumption and integrated Digital Diagnostics Monitoring (DDM), it is ideal for use in data centers, metro aggregation, and enterprise long-haul backbones.
