LINK-PP L9-SC315501-20PPC bidirectional transceiver delivers reliable 155Mbps data transmission for SDH/SONET networks in an industry-standard 1×9 package. It integrates a 1310nm-TX/1550nm-RX BiDi optical design with a simplex SC interface to enable cost-effective 20km links over single-mode fiber.
This optical transceiver adopts a standard 1×9 footprint fully compliant with MSA guidelines for straightforward hardware integration. It features (LV)PECL differential inputs/outputs, (LV)PECL signal detect, very low EMI, and certified ESD protection to ensure stable operation.
A sustained data rate of 155Mbps meets the stringent timing and synchronization requirements of OC-3/STM-1 links. This makes the module ideal for SDH/SONET access platforms and telecom transport systems operating over single-fiber lines.
Single-fiber bidirectional communication is established through 1310nm upstream transmission and 1550nm downstream reception. This complementary wavelength configuration allows concurrent send-and-receive operations through a shared fiber core.
An optimized optical link budget allows signals to travel up to 20km across single-mode fiber without extra amplification. This distance capability easily bridges connections across campus backbones and metropolitan carrier spans.
The simplex SC optical receptacle provides secure, repeatable mating with standard single-fiber patch cords. This compact single-port design doubles usable fiber capacity while reducing cable congestion on host boards.
Manufactured under strict ISO 9001 quality management, this 155M 1×9 BiDi transceiver meets CE, RoHS, and FCC international standards for safety, environmental compliance, and electromagnetic compatibility.
Each 1×9 BiDi module undergoes rigorous optical and electrical screening to guarantee reliable signal integrity and long-term operating stability.
Official regulatory approvals verify that the transceiver satisfies demanding telecommunication quality benchmarks and environmental safety rules worldwide.
The standard 1×9 pin layout ensures seamless mechanical and electrical fit onto host boards across diverse networking equipment brands.
Every 1×9 155M BiDi optical transceiver passes comprehensive evaluations to ensure stable single-fiber bidirectional transmission across diverse operating conditions. Discover full details about our testing procedures at the LINK-PP Test Support Center.
