Voice over fiber

AN-FM-PCM30 là thiết bị truyền 30 kênh FXO/FXS qua cáp quang

AN-FM-PCM30 fiber mux is an optical transmission equipment realizing long-distance voice transmission through fiber. Primary interfaces are FXS/FXO but additional E1, Ethernet or E1 can be added upon request

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.

     AN-FM-PCM30 fiber mux can provide 1-8 channels, 1-16 channels, 1-24 channels, or 1-30 channels telephone 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.

Additional channels of E1, Ethernet and RS-232 can be added upon request

• Low cost solution for delivering analogue POTS lines over long distance fibers;
• up to 30 FXO ports for connection to PABX or PSTN;
• up to 30 FXS ports for connection of phones or faxes;
• Ethernet port for LAN interconnection;
• RS-232 for data transmission
• Up to 4E1 ports as an option for PABX interconnection or any other E1 Leased lines services
