Voxtel has announced the release of its 'Siletz' series of APD receivers, responding to the demand for eye-safe and highly sensitive optical communications, LIDAR, and LADAR in the near infrared (NIR) spectrum. Voxtel's Siletz APD receiver optical subassembly provides sensitivity 2 to 4 dBm improved over any other APD receiver currently available on the market covering the 950-1700 nm spectral range, and operates at frequencies up to 2.7 GHz.
Voxtel's Siletz receiver series is based on its patented single carrier multiplication InGaAs APD (SCM-APD). The SCM-APD has higher gain (M > 50) and lower excess noise (F(M) ˜ 2) than conventional APDs. The higher gain and lower avalanche noise of the SCM-APD provides amplification of the NIR optical signal over the amplifier noise floor, providing better than –44 dBm noise equivalent power (NEP) and superior bit error rate (BER) performance over the entire frequency range. The SCM-APDs provide 2x better temperature stability compared to conventional APDs, reducing demands on bias stabilization and temperature compensation.
The REP-1XJ0A model Siletz receiver is packaged in a hermetic TO-8 package with a thermoelectric cooler (TEC). The TEC provides the ability to stabilize the APD temperature, easing the system integration effort. The APD receiver is available with the option for single- and multi-mode fiber tails.
Voxtel's SCM-APD receiver is a high-performance product not yet available from any other manufacturer.
