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

LINK-PP L9-SD311G-20PPC optical transceiver combines classic 1×9 pin packaging with 1 Gbps speed and a reliable 1310nm optical setup. Every design element — from its 20km reach to its duplex SC port — is built directly around standard 1×9 board layouts for stable fiber communication.

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

This pin-through module uses an industry-standard 1×9 footprint with direct PECL data inputs and outputs for easy circuit board soldering. It also provides a clear LVPECL signal-detect pin so the host board can instantly check link status.

L9-SD311G-20PPC: 1 Gbps Connectivity for SONET/SDH Backbones

Delivering a stable 1Gbps data rate, this 1×9 module easily handles the continuous traffic requirements of core SONET/SDH backbones. The consistent speed helps legacy telecom infrastructure pass heavy optical data loads smoothly from point to point.

L9-SD311G-20PPC Module with 1310nm Wavelength

The internal FP laser transmitter emits light at the 1310nm window to keep optical dispersion and loss very low. By matching this wavelength, the module keeps light signals clean as they travel down single-mode fiber lines.

L9-SD311G-20PPC Module Supporting 20km Transmission

Strong optical link power allows this 1×9 transceiver to push data across 9/125μm single-mode fiber for up to 20km. This span lets technicians connect distant stations directly without adding extra optical boosters along the route.

L9-SD311G-20PPC Module with Duplex SC Interface

A built-in duplex SC optical connector provides a firm, click-to-lock fit on the front panel of the 1×9 package. Its snap-in housing keeps patch cords firmly seated to prevent accidental disconnections during routine maintenance.


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

LINK-PP L9-SD311G-20PPC complies with major international standards, including ISO 9001, CE, RoHS, and FCC guidelines. These credentials ensure the 1×9 optical transceiver satisfies strict global rules for environmental safety, manufacturing quality, and electromagnetic limits.

Optical Transceivers Testing

Every 1×9 optical transceiver passes thorough electrical and optical checks before leaving the factory. Technicians measure signal integrity, optical output power, and receiver sensitivity to confirm reliable daily field performance.

L9-SD311G-20PPC Quality Certifications

Official industry certificates confirm this 1×9 transceiver meets all essential electrical and environmental standards. It provides proven build quality, ensuring the module works safely and reliably in any standard telecom setup.

Standard Multi-Vendor PCB Footprint Compatibility

The standardized 1×9 pin layout aligns perfectly with common circuit board drill patterns across various hardware brands. System engineers can solder the module onto host boards easily without modifying existing trace routes or mechanical layouts.


Rigorous Testing Ensures Reliable 1×9 Performance

Every 1×9 optical transceiver undergoes thorough hardware inspections to guarantee stable link quality and long service life. To explore our complete quality verification procedures, please visit the LINK-PP Test Support Center.
