VERSITRON'S E1 fiber optic modem allows distances to 30 kilometers and is now available in both multimode and single mode. Use of single mode optics makes the 30 kilometer distance possible. All of our standard features remain in tact including synchronous, full-duplex, half-duplex or simplex data transmission at 2.048 Mbps with fully transparent operation. This product line supports CCITT G.703 E1 standards. These are offered in several different configurations to accommodate a wide a variety of f.o. needs.

To match specific communication link distance requirements, the F2400 Group E1 Interface Extenders incorporate interchangeable optical modules that may be installed easily in the field. This permits quick, convenient upgrades as system requirements change. Mounting options include all of the VERSITRON FOM II chassis--HF-1 and HF-2 desktop enclosures, and HF-2SS and HF-20 rack-mount chassis.

To accommodate quick low cost system expansion and enhancements, the F2400 Group E1 Interface Extenders employ the latest FPGA technology. The F2400 products transmit and receive data using a proprietary VERSITRON encoding scheme. The sampling rate of the data signals is approximately 16 MHz. These products provide high-density bipolar order 3 (HDB3) and AMI data format conversion. Other features include two interface connector options, LED status indicators, and a loopback switch to troubleshoot the copper and optical portions of the circuit.

Model F2412: 850nm, ST Connector, 3 km (operating distance)

Model F2414: 1300nm, ST Connector, 15 km (operating distance)

Model F2415: 1300nm ( single mode), ST Connector, 30 km (operating distance)

Other VERSITRON products include: T1, telephone products (2-wire, 4-wire, multiplexer), f.o. modems for a variety of interfaces (RS-232, RS-530, RS-485, RS-422, RS-449, DS3), and an extensive line of media converters, optical switches, and VersiVision video products for CCTV applications.

Of special interest among our other products is our RS-485 TeleData fiber optic modem. Use it as a telephone interface, use it as a data interface or use it as both. The F270X/F271X is capable of transmitting both voice and data signals simultaneously over one duplex f.o. cable. Available in both multimode and single mode, this product can accomodate distances to 30 km. And, if you need a 4 wire telephone product that can simultaneously send voice and data signals as well, we have the product for you.

Also of interest is our new 10/100/1000 6 port optical switch. Operating as a "little, big man", this switch performs tasks associated with large switches. You will find GBIC technology and web smart management in this compact switch, in addition to several other features that will impress you.
