Phone fiber mux is an optical transmission equipment realizing long-distance voice transmission through fiber. This equipment uses design of ultra large scale integrated circuit, and its outward appearance is succinct. The merits include easy installation and debugging, unnecessary for maintenance and steady performance. It is suitable in business for communication operator, government and kinds of entities.

Phone fiber mux can provide telephone 1-30 channels through optical cable, the network application is point-to-point, supporting FXO/FXS. It has solved telephone transmission problem of edge customers. This equipment uses special digital multiple-connected chip whose function is formidable, and it integrates nearly all the digital logical function of equipment, thus remarkably enhancing product performance and reducing cost.

This equipment works stable and reliable and has good performance such as low power consumption, high integration rate, small volume and easy for installation and maintenance.
