HFBR-1312T Transmitter
HFBR-2316T Receiver
1300 nm Fiber Optic Transmitter and Receiver
Data Sheet
Description
The HFBR-0300 Series is designed to provide the most
cost-e ective 1300 nm ber optic links for a wide variety
of data communication applica tions 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
transmit ter and receiver are compatible with two popular
optical ber sizes: 50/125 m and 62.5/125 m diameter.
This allows exibility in choosing a ber size. The 1300 nm
wave length is in the lower dispersion and attenua tion
region of ber, and provides longer distance capabilities
than 820 nm LED technology. Typi cal distance capabilities
are 2 km at 125 MBd and 5 km at 32 MBd.
Transmitter
The HFBR-1312T ber optic transmitter contains a 1300
nm InGaAsP light emitting diode capable of e ciently
launching optical power into 50/125 μm and 62.5/125
m diameter ber. 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 con tains an InGaAs PIN photo-
diode and a low-noise transimpedance preampli er that
operate in the 1300 nm wavelength region. The HFBR-
2316T receives an optical signal and converts it to an
analog voltage. The bu ered output is an emitter-follow-
er, with frequency response from DC to typically 125 MHz.
Low-cost external compo nents 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.
