Optical Path Exchange

Optical Path Exchange
Software Defined Physical Infrastructure by Fiber Mountain
OPX is a software-controlled Layer 1 switch offering 160 ports in a slim 1 RU form factor with 5 nanosecond port-to-port latency.

The Fiber Mountain Optical Path Exchange (OPX) provides any port-to-any port connectivity, creating a Virtual Connectivity Fabric, for point-to-point and point-to-multipoint applications, in a slim form factor of one Rack Unit (1RU). OPX provides cross connect of 160 ports (320 fibers) terminating within fourteen 24-fiber MPO faceplate connectors and only 5 nanoseconds latency port-to-port.

OPX is fully managed from the Fiber Mountain AllPath Director.

All MPO ports support Intelligent Connection Identification (ICID) technology, allowing for a fully visible and dynamically moveable physical layer. This software control of physical connections is also known as Connectivity Virtualization.

An integral part of Fiber Mountain’s Glass Core, OPX enables the creation of Programmable Light Path (PLP) connections for dynamic reconfiguration of paths in the Glass Core architecture. Scalable to 40G, 100G and above, it is also a valuable asset in extending the life of a 10G or 40G infrastructure.

OPX is also available as a standalone unit to work in any SDN environment controlled by a third party controller.
