Description
The OPF0400 series is a cost effective solution for 850 nm
fiber optic link designs. The transmitter and receiver pair are
designed for use with multimode optical fiber with either
50/125µm or 62.5/125µm diameters. This fiber optic pair is
housed in a space saving, auto-insertable package that is
compatible with most wave solder processes.
Receiver
OPF2416 is a low cost solution for high speed, fiber optic
communications designs. The internal lensing of this re-
ceiver’s design allows optimal response from fiber sizes of
100µm and below.
The receiver is comprised of a high speed, low noise, photodi-
ode coupled to a transimpedance amplifier (TIA). The photo-
diode/TIA combination produces an output voltage that is pro-
portional in the input light amplitude. This hybrid approach
solves many of the problems of high speed data link designs
by placing the photodiode close to the TIA. The amplification
of the TIA makes the output much less susceptible to EMI.
The output of the OPF2416 is an analog, low impedance,
emitter follower voltage source. Subsequent circuitry can
utilized to convert the analog voltage to ECL/TTL for digital
data rates up to 155 Mbps.
The OPF2416 is available with either standard or threaded
panel mount ST® receptacles. The threaded version is also
available in conductive plastic. Refer to the part number
guide for more details.
