Overview

The FOI-4110-RS-ST is a member of the FOI-4110 product series. The FOI-4110 fiber optic isolator uses 820nm optics as a low cost solution for 10BASE-T to 10BASE-FL and 100BASE-TX to 100BASE-SX Ethernet communications. The 820nm optics also provide backward compatibility with legacy devices that have a 10BASE-FL interface.

The units will have an automatic MDI/MDIX switch over capability that allow users to use either a straight or crossover cable for all LAN configurations. This eases the installation process for simple plug and play. A typical link consists of two FOI-4110, one at each end of the network, with a duplex fiber optic cable between them.

The units can be used in areas of high electrical noise or in and out of RF shielded enclosures. The fiber optic cable is not susceptible to interference caused by impulse noise, crosstalk, or EMI. FiberPlex recommends “R” units for high security applications because they have added filtering and shielding for RFI suppression.

Flexible Mounting and Powering Options

The FOI-4110-RS-ST is part of the FOI line of products designed for ruggedized mil applications. It is housed in the familiar FOI shielded can enclosure. For standalone applications it can be powered by adding a PSQ-4909 AC supply or a PSQ-4920 DC power supply (not included). Optionally, up to 8 FOI units can be mounted on CMA chassis adapters and installed in an RMC-3101 or RMC-2101 rack mount chassis. The units are powered redundantly by a common back plane connection.
