Excalibur 10 Gigabit Ethernet Transponders

Excalibur Ethernet Transponder

Moog Protokraft Excalibur series optical fiber transponders consist of optoelectronic transmitter and receiver functions integrated into a bulkhead mounted MIL-DTL-38999, series III receptacle connector along with the 10 Gbps / XAUI SerDes functions. The optical transmitters are 850 nm VCSEL lasers. The optical receivers consist of PIN and preamplifier assemblies and limiting post-amplifiers. The XAUI electrical interface to the Excalibur series optical fiber transponders is a Samtec® controlled impedance connector enabling interface to a ribbon coax cable or flexible printed circuit assembly.
