The FireFiber® HMP series transceiver modules provide up to four channels for optical communication at data rates from 100 Mbps up to and exceeding 2.488 Gbps per channel. They utilize common hermetic packaging and an innovative hermetic fiber feed-through technique. Wavelengths offered include 1310 nm and 1550 nm with various fiber-optic interconnect options. The HMP Series transceivers are designed and fabricated to meet the rigors of military and space qualification via design, assembly, and qualification techniques dictated by MIL-PRF-38534E, EEE-INST-002, and MIL-STD-883F. These optical devices provide enhanced power, size, and mass reduction in addition to EMI, EMP, and Radiation environment immunity over conventional non-optical transceiver modules and copper-based interconnects.
