Gemini Series Straight Media Adapters

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. A CMOS fault signal is generated on the TX Fault line by the module controller upon any monitored internal optical or electrical fault condition. The receiver data lines are squelched upon LOS assertion, preventing errant data packet generation when an invalid incoming optical signal is presented to the transceiver. The electrical interface to the Gemini series optical transceiver dongles is a Mil-Dtl-38999 Serie III plug connector with 66 Size 22 electrical contacts

Gemini series optical fiber transceiver dongles are vibration isolated, environmentally hardened components designed for use in harsh environment applications.
