Product Overview
The FQ2CL-MM-2LC-1M 2-Channel Multimode Expanded-Beam Fiber Optic Circular Receptacle is a ruggedized fiber optic chassis connector designed for professional audio, live sound, broadcast, stage production, rental AV, and other demanding fiber optic applications.
The connector uses expanded-beam spherical optical technology with a non-physical-contact optical interface. Instead of directly contacting the fiber end faces, the optical beam is expanded and transmitted through the optical interface, helping reduce the effects of dust, dirt, and contamination and providing stable optical performance during repeated mating.
The receptacle features a thread-locking mounting and mating structure for secure installation and reliable operation in mobile and professional environments. It is designed for 2-channel multimode fiber transmission and provides an IP67-rated enclosure for protection against dust and water.
The connector is suitable for installation on professional equipment and can be used with systems requiring ruggedized expanded-beam fiber connectivity, including applications associated with DiGiCo-style professional audio interfaces and stage systems.

Expanded-Beam Optical Technology
The connector uses a spherical expanded-beam optical structure to transmit optical signals without direct physical contact between the fiber end faces.
The optical beam is expanded before passing through the connector interface and then optically focused back into the receiving fiber. Because the optical beam is significantly larger than the fiber core, small amounts of dust or contamination have less influence on the transmitted optical power than with conventional physical-contact interfaces.
This type of expanded-beam technology is widely used in ruggedized fiber optic systems for touring, broadcast, military, industrial, and harsh-environment applications. Commercial expanded-beam systems are available in both 2-channel and 4-channel configurations.
