HOD1344-312/DBA Single Fiber Duplex Modules FEATURES * Full duplex over single fiber * DC to 85 MHz link bandwidth * 2 km+ link budget * 40 dB isolation * Close Mounting Housing * Other options available OPHO_228.doc 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. OUTLINE DIMENSIONS in inches (mm) The HOD1344-312/DBA comprises an 850nm LED and a 1300nm PIN diode and it's corresponding part, HOD2132-122/DBA, 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 has a high profile for mounting duplexers side by side and minimising lead length between PIN and PCB, the component ports are positioned to the rear and underside of the housing. 616 ODIM_227.cdr Pinout End view Underside view 1.
