VersaLogic is proud to offer an Ethernet over Fiber optic Mini PCIe module. This module allows almost any computer equipped with a Mini PCIe socket to be upgraded with a fiber optic link. The industrial temperature MPEe-E4 (-40° to +85°C operation) is designed for harsh environments and qualified to MIL-STD-802G for high vibration environment. The E4 is designed for high reliability applications and is also supported by a long production life. The E4 uses bi-directional fiber optic cable for Ethernet communications instead of the standard CAT 5 copper cable per the IEEE 802.3. The transceiver on the board is a multimode (short haul) type. The transmission laser is an 850 nm Class 1, the light output is similar to a laser pointer so that no eye protection is required (though it is recommended to not look directly at the light). The transceiver housing is metal to shield the data against electro-magnetic interference. The connection between the E4 and the fiber is an industry standard LC style latching fiber optic connector. There are two types of fiber optic cable available to interface with the E4: 62.5 OM1 fiber which is used for distances up to 300 meters, or 50 µm core OM2 fiber that provides distances to 550 meters. Communications between the E4 and the host computer is through a PCI express lane so there is low latency communicating with the host CPU. The Ethernet media access controller (MAC) on the E4 is an Intel i210 device. There are standard pre-configured drivers available in most Linux and Windows operating systems to support the i210, so no additional software should be needed. VersaLogic developed the MPEe-E4 relying on over 40 years of experience supplying embedded computer boards to industrial, medical, and defense customers. The following slides provide details of the Ethernet over Fiber Optics capabilities. Like all of VersaLogic’s rugged embedded computers and mini PCIe modules, the MPEe-E4 is designed, manufactured, and tested to be reliable in critical and demanding environments. These environments include extreme temperatures, high shock, excessive vibration, and high humidity. It has gone through: a strict component selection and evaluation process, worst-case stress testing, state-of-the-art compliance and validation testing of all high-speed signals, verification of the external interfaces, and extensive power and four-corner thermal testing. All VersaLogic products have been through the most stringent validation testing before they take on a customer’s application.
