Neptune Series M28876 Ethernet Media Converters

Protokraft Neptune series fiber optic Ethernet media converters consist of optoelectronic transmitter and receiver functions integrated along with the 10/100Base-TX to 100Base-FX or 1000Base-T Ethernet electrical to 1000Base-LX or 1000Base-SX Ethernet optical media conversion circuitry into an environmentally sealed unit.

The optical transmitters are high performance 1310nm FP Lasers, LEDs or 850nm VCSEL's. The optical receivers consist of GaAs or InGaAs PIN and preamplifier assemblies and limiting post-amplifiers.   The optical interface to the Neptune series optical media converters is a Mil-Dtl-28876 fiber optic connector enabling interconnection to preterminated M28876 optical fiber cable assemblies.  The electrical interface to the Neptune series optical media converters is an Amphenol D38999 Size 19-18 Quadrax connector enabling interconnection to quadrax cable assemblies.
