Moog Protokraft Dagger series D38999 transceivers, transmitters and receivers consist of optoelectronic transmitter and receiver functions integrated into a wall mount D38999 cylindrical connector. The optical transmitters are 850nm 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 and single ended CMOS indicator functions on the Loss of Signal (LOS) lines. The receiver data lines are squelched upon LOS assertion, preventing errant data generation when an invalid incoming optical signal is presented to the transceiver.
The optical mating interface of the Dagger series product family is an ELIO® fiber optic cable plug per EN 4531. The electrical interface to the Dagger series product family is a ribbon coax to Samtec® EQCD high density cable assembly enabling SMT interconnection to a customer's backplane, motherboard or daughtercard.
