The D38999 connector provides a rugged electrical interface that does not require cleaning or maintenance to perform in extreme and harsh environments. The multimode or single mode optical fibre cable supports applications where copper cable link distance, bandwidth, weight or bulk make the use of twisted pair, twinax or quadrax copper conductors unacceptable.
Suitable for Fast Ethernet, Gigabit Ethernet,1x/2xFibre Channel and sFPDP applications from 50Mbps to 3.2Gbps.
Other solutions are available including: PCIExpress, Hotlink II, RS422/LVDS, USB to RS232/RS422, Contact us for details...
Gemini series media interface adapters consist of optoelectronic transmitter and receiver functions integrated into a bulkhead mounted MIL-DTL-38999, series III receptacle connector assembly. The optical transmitters are 850 nm VCSEL or 1310 nm FP lasers.
The transmitter input lines are driven with differential CML signals applied to the transmitter (TX+ and TX-) lines. Dual loop, temperature compensated, VCSEL laser drivers convert the transmitter input signals to suitable VCSEL laser 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.
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.
