Specifications
Wavelength range
Minimum Typical Maximum Units
up to 12.5 Gb/s. The back-illuminated
PIN photodiode design optimizes speed
and sensitivity for the 1200 nm through
1650 nm wavelength range. The internal
Clean-pulseTM design assures low group-
delay response necessary for time-domain,
digital applications.
