Optical Path Exchange


Fiber Mountain’s Glass Core integrates software and hardware innovations to transform network infrastructure. AllPath Director, OPX, Sensus and L-Series Products combine software orchestration, physical layer intelligence and high-density fiber optics to enable Managed, Dynamic and Secure physical networks.

Product Description

Fiber Mountain’s OPX family of layer 1 SDN switches and cross connects is an integral part of Fiber Mountain’s Glass Core, enabling the creation of Programmable Light Path (PLP) connections for dynamic reconfiguration of paths in the Glass Core network architecture. This software control of physical connections is also known as Connectivity Virtualization.

The AP-4240 OPX provides any port-to-any port connectivity, through its fabric, for point-to-point and point-to-multipoint applications, in a slim form factor of one Rack Unit (1RU). It provides cross connect of 160 ports (320 fibers) terminating within fourteen 24-fiber MPO faceplate connectors, and is fully managed from the Fiber Mountain AllPath Director, an SDN orchestration system designed to make full use of Intelligent Connection Identification (ICID) technology. The AP-4240 OPX provides fourteen ICID-enabled 24-fiber MPO ports, allowing for a fully visible and movable physical layer. It is also available as a standalone unit to work in any SDN environment controlled by a third party controller.
