• 2km+ link budget
• 40dB isolation
• Close mount ST housing
• Other options available
Description
The Honeywell HOD-XXXX series of dual wavelength 'Fibre Duplexers' allow communication over a
single optical fibre link. Applications include full duplex data transmission, multiplexing two signals
to a single fibre, LED coupled power measurements and reflected power measurements, depending
upon the configuration of the duplexer.
The HOD2135-142/GBA comprises a 1300nm LED and an 850nm PIN Diode and its corresponding
part, HOD1340-312/GBA, comprises an 850nm LED and a 1300nm PIN Diode. The pair facilitate full
duplex communication over a single fibre and are designed to be used where a dual fibre 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 fibre via integral lenses and a 3dB 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 2km+ are possible
with this duplexer pair depending upon the receiver circuitry used. The duplexer housing is a special
low profile design, being the same width as a standard ST for close mounting, the component ports are
positioned to the rear and underside of the housing.
Other standard options are available on request. These include two LEDs in one duplexer for single
fibre multiplexing, PIN+Preamp receivers, VCSEL emitters or any other preferred components.
Housing options include SC or FC/PC optical ports or a low profile ST housing the same height as a
standard ST.
