Get up to 40 dB of dynamic power control in a single channel using our (Bright type) ultra mini Variable Optical Attenuator (VOA) based on innovative ES-MEMS technology.
These devices are available for either C- or L-Band use and require only a low (0-5.5 V) drive voltage. They feature an insertion loss of only 0.8 dB (at V=0). They are also fast with a response time of just 5 ms. Plus they are very durable, delivering >109 cycles.
Applications include all types of power management such as power balancing between amplification stages, as well as channel equalization and channel balancing.
Low Insertion Loss
Large attenuation range
Low power consumption
SiC Circuitry Makes EVs Better
Coherent is one of the few companies worldwide with a complete, vertically integrated SiC manufacturing capability. We produce SiC wafers and epitaxy, all the way through power devices and modules. Furthermore, the unmatched quality with which we can produce SiC material makes Coherent virtually the only supplier positioned to successfully transition from the current standard wafer diameter of 150 mm up to 200 mm.
