Fiber Optic Analog Telephone Modems

2 Wire, 4 Wire, Mux, TeleData | Telephone and Data Multiplexer | Up to 152 Analog phone lines over 1 Fiber

If you are looking for a fiber optic telephone modem, VERSITRON has several options for you. We offer a 4 wire analog option, with new stereo audio capabilities, a standard 2 wire option, an enhanced two wire option with data capabilities — The "TeleData", and a phone mux — with an astounding number of configuration possibilities for many standard serial data interfaces — called the Versimux II. A fully populated Versimux II chassis can accommodate 152 voice lines.

You can access a design drawing here for an example of how these products can be used.

VERSITRON'S four wire devices provide full-duplex secure voice communications at distances up to 100km with fully transparent operation. These products convert analog voice lines OR stereo audio signals into light pulses for transmission over fiber optic cable. Two versions are available which provide an interface to central office voice grade signals. Model F2722B utilizes multimode fiber and Model F2725B utilizes singlemode fiber. All models have LC optical connectors, a DB9 electrical interface, and 1/8" TRS audio connectors. In addition, any of the models can be used in the VERSITRON FOM II enclosures and chassis or the Versimux II chassis.

Our standard two wire units convert a POTS loop start analog voice circuit to light signals for transmission over f.o. cable. The analog circuit of these devices supports data up to 14.4Kbps vial dial-up or fax. We offer:

  • Distances to 100km
  • 6 status indicators
  • VERSITRON FOM II format
  • SFP fiber optic module technology

The "TeleData" when used in its enhanced version, can also extend a data link (RS-485 or RS-422) as well as a voice link. In fact, you can send voice and/or data signals at the same time using "one" f.o. cable! The F270xAD functions as the exchange side device while the F271xAD functions as the subscriber side device. For intercom or ring down application, the F271xAD is used at each end of the connection. An RJ11 provides the copper interface for voice and an RJ45 provides the copper interface for the RS-485, RS-422 data. LC connectors are standard. Several different configurations are offered to accommodate a wide variety of applications. The operation of each converter is fully transparent. Distances as follows:

  • 1310nm (MM) - 2Km
  • 1310nm (SM) - 20km

The Versimux II  f.o. multiplexer is capable of handling up to 152 analog POTS lines over one fiber. Using plug-in cards supporting 1, 4, or 8 voice lines, numerous configuration options are available to the end-user, saving costs and permitting quick updates to the overall system. SFP technology is incorporated in all the Versimux II products. These products utilize an exchange card at the PBX end of the application, connected via f.o. cable to a subscriber card at the voice end of the application. Multimode and singlemode options are available with distances up to 80km possible.
