Proteus Media Interface Adapter

Proteus Media Interface Adapter

Moog Protokraft Proteus series media interface adapters consist of optoelectronic transmitter and receiver functions integrated into an external bulkhead mounted MIL-DTL-38999, Series III receptacle connector assembly. The optical transmitters are 850 nm VCSEL lasers.

The transmitter input lines are driven with differential CML signals applied to the transmitter (TX+ and TX-) lines. Dual loop, temperature compensated, VCSEL drivers convert the transmitter input signals to suitable VCSEL bias and modulation currents. The optical receivers consist of PIN and preamplifier assemblies and limiting post-amplifiers. Outputs from the receivers consist of differential CML data signals on the receiver (RX+ and RX-) lines. The electrical interface to the Proteus series is a D38999 19-18 connector with four quadrax contacts.
