Protokraft Introduces Mercury Family Of Mil-Dtl-38999 Based Ethernet Optical Media Converters For 28VDC Applications

Kingsport, TN - Protokraft recently announced the introduction of the Mercury Series of Mil-Dtl-38999 Ethernet Optical Media Converters to simplify avionics equipment designs and improve Ethernet network performance and reliability in harsh environment applications. Protokraft adds the new Mercury series to its previously announced Spitfire, Lightning and Magnum series of harsh environment optoelectronic interfaces to offer a comprehensive optical component solution for Military and Commercial avionics optical networks.

The Mercury Series of Mil-Dtl-38999 Ethernet Optical Media Converter are available in Single and Dual port versions and are designed for military, aerospace, industrial or utility applications where significant levels of shock, vibration and extreme temperature ranges are experienced. Mercury series Fast Ethernet or Gigabit Ethernet media converters consist of optoelectronic transmitter and receiver functions integrated along with the Ethernet media conversion circuitry into a wall mount Mil-Dtl-38999 connector assembly. The optical transmitters are high output 850nM VCSEL lasers or 1310nm LED's. The optical receivers consist of GaAs or InGaAs PIN and preamplifier assemblies and limiting post-amplifiers.

The electrical signal and power interfaces to the Mercury series optical media converters are Mil-Dtl-38999 connectors. Mercury series Ethernet media converters are vibration isolated, environmentally hardened components designed for use in harsh environment applications. Separate electrical signal and power connectors enable compliance to Mil-Std-461K and Mil-Std-704.

The Mil-Dtl-38999 connectors provide sealed interfaces that are water-tight to Mil-Std-810 when mated. The multimode optical fiber interface supports applications where copper cable link distance, bandwidth, weight or bulk make the use of twisted pair, twinax or quadrax copper conductors unacceptable.

Mercury Series Mil-Dtl-38999 Ethernet Optical Media Converters are ideal for use in outdoor network communications and display systems where small size, reduced weight and resistance to harsh environments are required.

Designed to operate in harsh environments, these new media converters feature excellent thermal characteristics, high tolerance to shock and vibration and corrosion resistant Olive Drab Cadmium or Electroless Nickel plated aluminum shells for exceptional EMI/RFI performance. Standard case operating temperature range is -40C to +85C, with a standard storage temperature range of -55C to +100C. The Mercury Series Ethernet Optical Media Converters operate at link distances up to 2.0 Kilometers. All operate from +28VDC (18VDC to 36VDC) power supplies.

Protokraft's Mercury Series Ethernet Optical Media Converters are competitively priced compared to the typical discrete optical devices and systems which have been designed for harsh environments. Mercury Ethernet optical media converters are available now with lead times for all versions in the range of stock to 8 weeks ARO.
