DESCRIPTION
The Honeywell HODxxxx series of dual wavelength 'Fiber
Duplexers' allow communication over a single optical
fiber. Applications include full duplex data transmission,
multiplexing two signals to a single fiber, LED coupled
power measurements and reflected power
measurements, depending upon the configuration of the
duplexer.
The HOD4013-132/BBA comprises an 850 nm LED and
a 1300 nm PIN diode and it's corresponding part,
HOD3021-212/BBA, comprises a 1300 nm LED and a
850 nm PIN diode. The pair facilitate full duplex
communication over a single fiber and are designed to be
used where a dual fiber solution is not possible or
economical. Alternatively the duplexer can be used to
double the capacity of an existing system.
Each part consists of an on-axis port and an off-axis port
loaded with the appropriate components, these are then
coupled to the single fiber via integral lenses and a 3 dB
wavelength differentiating mirror within the duplexer
body. In this configuration the two pairs of components
can communicate in opposing directions simultaneously
and independently of each other. Links of 2 km+ are
possible with this duplexer pair depending upon the
receiver circuitry used. The duplexer housing is low
profile, being the same height as a standard ST, the
component ports are positioned to the rear and side of
the housing.
Other standard options are available on request. These
include two LEDs in one duplexer for single fiber
multiplexing, PIN + Preamp receivers, VCSEL emitters or
any other preferred components. Housing options include
SMA, SC or FC/PC optical ports or a high profile housing
for mounting duplexers closely side by side.
Honeywell reserves the right to make
changes in order to improve design and
supply the best products possible.
