SERIAL / ETHERNET FIBER OPTIC CONVERTERS

RS232/RS485/RS422 to Fiber Optic Converter

RS232/RS485/RS422 to Fiber Optic Converter

    The CommFront FBR-Serial-2 (Rack/Wall-mount) is a rugged, industrial-grade (-40F to 185F / -40C to 85C), multi-function RS232 / RS485 / RS422 to fiber optic converter (fiber optic modem) that supports asynchronous serial communications (RS-232, RS-485, and RS-422) through fiber optic links. Besides the capability of long distance data transmission, fiber optic products are inherently resistant to EMI/RFI and transient surges; therefore, they are ideal for data communications near heavy electrical equipment and other electrical or radio interference.

    This rugged industrial-grade Serial-to-Fiber-Optic converter operates within a wide temperature range (-40F to 185F/-40C to 85C), and features 600W surge protection and 15kV static protection. It requires no software drivers or flow control, making the unit a rugged, highly reliable, and truly plug-and-play device.

    Depending on the fiber cable and the type of converter used, a Single-Mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 24.8 miles (40 km), while a Multi-Mode fiber optic converter can extend the RS232 / RS485 / RS422 distance to up to 1.2 miles (2 km). Standards can be mixed and matched, so RS-232 devices can be connected to RS485 / RS422 devices, or RS485 (2-wire) devices can be connected to RS422 (4-wire) devices without using a converter and isolator.

    The FBR-Serial-2 comes with the options of ST, SC and FC connectors for fiber optic links, and, thanks to the professional and unique casing design, the product can be mounted directly on wall/panel or DIN Rail, without a need of using any unsecured adapters. A separate external power supply is included in the package.

    Baud rates: 300 to 115.2K Baud.
Ethernet to Fiber Optic Converter

Ethernet to Fiber Optic Converter

    The CommFront FBR-Ethernet-2 is a 10/100M Ethernet to fiber optic media converter, which provides one channel for media conversion between 10/100BaseTX and 100BaseFX.

    Depending on the fiber cable and the type of media converter used, a multi-mode media converter can extend the 10/100M Ethernet distance to up to 1.2 miles (2 km), while a single-mode media converter can extend the distance to up to 12.4 miles (20 km).

    The FRB-Ethernet-2 is a plug and play unit featuring auto-negotiation for half or full-duplex and 10 or 100Mbps data rates, it also supports MDI (straight-through) and MDIX (crossover) cables, no DIP switch or jumper settings are required.
