Key Features of LINK-PP L9-SD311G-20PTC 1G 1×9

LINK-PP L9-SD311G-20PTC transceiver module provides dependable 1Gbps connectivity using an industry-standard 1×9 pin layout. The module operates at 1310nm with a duplex SC port, allowing smooth and reliable communication up to 20km on standard single-mode fiber.

LINK-PP L9-SD311G-20PTC 1G 1×9 Optical Module

The industry-standard 1×9 footprint features a classic 9-pin pinout for direct wave soldering onto system motherboards. Internal differential PECL input and output lines pair with a TTL signal-detect pin to report optical reception status.

L9-SD311G-20PTC: 1 Gbps Connectivity for Telecom & Carrier Networks

A steady 1Gbps data rate allows this 1×9 module to handle standard SDH and SONET voice and data traffic smoothly. Carrier networks use this fixed speed to connect core switches and telecom cabinets without packet loss.

L9-SD311G-20PTC Module with 1310nm Wavelength

An internal 1310nm FP laser sends clear optical beams through single-mode fiber with very low distortion. Operating at this specific wavelength keeps the light pulses clean so data stays readable over long runs.

L9-SD311G-20PTC Module Supporting 20km Transmission

Operating reach extends up to 20km across standard 9/125μm single-mode fiber without needing extra signal boosters. This link distance makes it easy to connect equipment located in separate buildings or distant network stations.

L9-SD311G-20PTC Module with Duplex SC Interface

The duplex SC optical receptacle provides dedicated channels for simultaneous signal transmission and reception. This standardized interface holds single-mode fiber patch cords firmly in place to prevent accidental link drops caused by cabinet vibration.


LINK-PP L9-SD311G-20PTC 1G 1×9 Certification
