4 Voice (FXS/FXO) POTS fiber multiplexer, 1 x Ethernet port as option Voice over Fiber mux series Fiber Optical Multiplexers AD-Net
Add Quotation


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-PCM04 fiber mux can provide 1-4 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 10/100 Ethernet can be implemented
Note, that 4 channels of FXS/FXO are connected at same RJ-45 port, so all 8 pins of RJ-45 connector are used, and additional cable of RJ-45 —-> 4 x RJ-11 should be used in case the connections are made directly to phone sets, but if RJ-11 cable are patched to LSA+ or other distribution panels, then it’s not necessary.


  • Low cost solution for delivering analogue POTS lines over long distance fibers.
  • up to 4 FXO ports for connection to PABX or PSTN.
  • up to 4 FXS ports for connection of phones or faxes.
  • Ethernet port for LAN interconnection.
  • MTBF more than 10 years.
  • WDM Bidi fiber interfaces avalaible.
  • 4 voice channels are connected at same RJ-45, all 8 pins therefore are used.
