LINK-PP L9-SD5501-80PPI5 is a dedicated 155M optical transceiver designed to provide dependable data transport across long-haul SDH and SONET infrastructure. Built in an industry-standard 1×9 footprint with a duplex SC interface, it transmits optical signals at 1550nm over 80km of single-mode fiber.
The transceiver complies fully with the multi-sourced 1×9 footprint protocol for easy board design and replacement. It also features standard (LV)PECL differential inputs and outputs, as well as a built-in (LV)PECL signal detect for link monitoring.
A steady 155Mbps data rate enables this module to support STM-1 and OC-3 telecommunication links with low latency. This makes it an ideal fit for long-range telecom access networks, power grid communications, and industrial control systems.
An optical emitter operating at the 1550nm center wavelength takes advantage of the lowest signal loss window in single-mode fiber. This low-attenuation design ensures optical signals travel smoothly over long fiber links without significant power drop.
Long-reach capability allows the module to send data up to 80km across standard 9/125μm single-mode fiber. As a result, network operators can connect distant sites directly without deploying costly optical amplifiers or repeaters.
A duplex SC receptacle provides an easy push-pull connection that locks securely with standard single-mode optical patch cords. Its sturdy connector body helps reduce signal loss and prevents accidental disconnections in demanding field installations.
The L9-SD5501-80PPI5 155M 1×9 module is manufactured under strict ISO 9001 quality management and meets global CE, RoHS, and FCC regulatory requirements.
Every 1×9 transceiver undergoes rigorous electrical, optical, and environmental screening to ensure reliable continuous operation in the field.
International compliance marks verify that the device satisfies mandatory safety standards and hazardous substance restrictions for worldwide deployment.
The industry-standard 1×9 pin layout ensures seamless mechanical and electrical drop-in fit onto host printed circuit boards across various networking platforms.
