iMUX unlocks network capacity within an existing fiber plant to achieve economies of scale, reduce capital expenditures and lower operational costs by creating simple, integrated and future-proof optical access networks. SOLiD’s patented tunable self-tuning transceivers along with optimally designed MUX/DEMUX and coordinated filters offer a cost effective DWDM solution for optical access in environments where operators experience fiber shortage. It supports point-to-multipoint and liner network topology. INFINITY ACCESS™ also provides a semi-passive option called iMUX+, which enables switching the WDM line into standby fiber when the working line is cut. • Eight tunable transceivers simplify WDM logistics and reduce inventory management costs • Self-tuning enables easy and fast installation • Patented software-based wavelength locking maintains the competitive price • Performance monitoring of remote transceiver through out of band channel • WDM line protection and AI enabled proactive maintenance supported by optional active electronics in head-end • Up to 96 wavelengths supported over a single strand • Compact and robust MUX/DEMUX and filters in LGX form factor Version 1.0 - October 2021 ©SOLiD.
