1300 nm Fiber Optic Transmitter and Receiver
Data Sheet
Description
The HFBR-0300 Series is designed to provide the most
cost-effective 1300 nm fiber optic links for a wide variety
of data communication applications from low-speed dis-
tance extenders up to SONET OC-3 signal rates. Pinouts
identical to Avago HFBR-0400 Series allow designers to
easily upgrade their 820 nm links for farther distance. The
transmitter and receiver are compatible with two popular
optical fiber sizes: 50/125 m and 62.5/125 m diameter.
This allows flexibility in choosing a fiber size. The 1300 nm
wavelength is in the lower dispersion and attenuation
region of fiber, and provides longer distance capabilities
than 820 nm LED technology. Typical distance capabilities
are 2 km at 125 MBd and 5 km at 32 MBd.
Transmitter
The HFBR-1312T fiber optic transmitter contains a 1300
nm InGaAsP light emitting diode capable of efficiently
launching optical power into 50/125 μm and 62.5/125
m diameter fiber. Converting the interface circuit from
a HFBR-14XX 820 nm transmitter to the HFBR-1312T
requires only the removal of a few passive components.

Receiver
The HFBR-2316T receiver contains an InGaAs PIN photo-
diode and a low-noise transimpedance preamplifier that
operate in the 1300 nm wavelength region. The HFBR-
2316T receives an optical signal and converts it to an
analog voltage. The buffered output is an emitter-follow-
er, with frequency response from DC to typically 125 MHz.
Low-cost external components can be used to convert
the analog output to logic compatible signal levels for a
variety of data formats and data rates. The HFBR-2316T is
pin compatible with HFBR-24X6 receivers and can be used
to extend the distance of an existing application by sub-
stituting the HFBR-2316T for the HFBR-2416.
