HMP-Series Ruggedized Hybrid Transceivers

FireFiber® HMP series transceiver modules provide up to four channels for optical communication at data rates from 100 Mbps up to and exceeding 3.25 Gbps per channel

Utilizing innovative techniques, FireFiber® includes 1310 nm and 1550 nm wavelengths with various fiber-optic interconnect options. While also having the option for radiation tolerance, these transceivers are truly unique.

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.
