Key Features of LINK-PP L9-SD5501-80PPI5 155M 1×9
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.
LINK-PP L9-SD5501-80PPI5 155M 1×9 Optical Module
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.
L9-SD5501-80PPI5: 155 Mbps Connectivity for Long-Haul SDH/SONET Links
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.
L9-SD5501-80PPI5 Module with 1550nm Wavelength
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.
L9-SD5501-80PPI5 Module with Duplex SC Interface
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.
LINK-PP L9-SD5501-80PPI5 155M 1×9 Certification
