LINK-PP L9-SD311G-20CTC is a through-hole 1×9 optical transceiver designed for 1Gbps Fibre Channel communication using a 1310nm optical link and a duplex SC connector. It provides stable point-to-point data links over single-mode fiber for distances up to 20km.
The module uses a standard 1×9 pin layout compliant with MSA standards for direct soldering onto host boards. It features simple CML differential data inputs and outputs with a clear TTL signal detect pin to show link status.
Data runs smoothly at 1Gbps speeds to match standard Fibre Channel storage equipment. This steady bandwidth helps connect storage servers and SAN switches without packet drops.
A built-in 1310nm FP laser transmitter sends clean optical signals over single-mode fiber with very low signal loss. This wavelength makes the transceiver fully compatible with common 1310nm optical gear and patch cables.
The through-hole pin design and stable internal optics provide enough optical power to transmit data up to 20km over 9/125μm SMF. This long reach allows the fixed-soldered 1×9 transceiver to bridge distant networking nodes without adding external optical boosters.
Soldered directly to the host PCB, this 1×9 transceiver module features a sturdy duplex SC optical connector for quick push-pull fiber mating. The integrated SC receptacle latches standard optical cords securely, preventing accidental disconnects in busy rack or cabinet installations.
LINK-PP L9-SD311G-20CTC complies with international ISO 9001, CE, RoHS, and FCC standards to ensure safety, environmental compliance, and reliable operation.
Each 1×9 transceiver undergoes strict optical output verification and signal integrity checks on the test bench to guarantee stable field operation.
Comprehensive certifications verify that this 1×9 transceiver meets strict international regulatory and environmental requirements for safe hardware deployment.
With an industry-standard 1×9 pinout, the module fits seamlessly onto common through-hole PCB layouts used across different equipment manufacturers.
Every 1G 1×9 optical transceiver undergoes thorough hardware inspections to guarantee dependable signal integrity across all operating environments. To explore our comprehensive validation procedures, visit the LINK-PP Test Support Center.
