(a) See the manual for complete specifications.
(b) The active area of the integrated Si Avalanche Photodetector is larger than 100 μm. The SPDMH2F and SPDMH3F modules are optimized for optical fibers as specified above. A pre-aligned GRIN lens focuses the light onto a spot of <70 μm diameter in the center of the detector.
(c) Specifications are valid for modules without the FC/PC connector.
