LINK-PP L9-SC315501-20PTC BiDi transceiver provides 155Mbps STM-1/OC-3 connectivity across 20km using a single-mode fiber strand. It brings together standard 1×9 housing, bidirectional wavelengths, and an easy-to-use simplex SC interface.
LINK-PP L9-SC315501-20PTC 155M 1×9 Optical Module
The physical package adopts an industry-standard 1×9 footprint fully compliant with the Multi-Source Agreement (MSA). It integrates (LV)PECL differential inputs/outputs and (LV)TTL signal detection while maintaining certified ESD protection and very low EMI.
L9-SC315501-20PTC: 155 Mbps Connectivity for STM-1/OC-3 Transmission
Designed to support SDH STM-1 and SONET OC-3 protocols, this interface delivers consistent 155Mbps data transmission. It is widely adopted across metropolitan transmission networks, telecom access rings, and legacy system modernization projects.
L9-SC315501-20PTC Module with 1310nm-TX/1550nm-RX Wavelength
The optical design pairs a 1310nm-TX channel with a 1550nm-RX channel to support full-duplex traffic on a single fiber core. This optical pairing lowers deployment costs by doubling data throughput per fiber run.
Optical link design allows sustained signal transport over single-mode fiber spans up to 20km without intermediate amplification. Its balanced power budget ensures low signal attenuation across mid-range network loops and campus distribution links.

It was supposed to work before but because of the issue I faced, I made an assumption. I was wrong, but later tests I ran made me re-evaluate. Actually, your Optical Transceiver Module allows me to support alternatives that were not available previously. I do not know why it was not working initially. But I'm all to happy to have it all working now.
