Honeywell HOD Series Single Fiber Duplex Module

A pair of Honeywell HODXXXX-XXX/BBA series of dual wavelength fiber duplex modules allows full duplex communication over a single fiber link. They may also be used where a dual fiber solution is neither possible nor economical. Alternatively, one duplex module may be used to double the capacity of an existing system.

Each duplex module consists of one on-axis port and one off-axis port, each configured with the appropriate devices. These devices are coupled to the single fiber via integral lenses and a 3 dB wavelength differentiating mirror within the duplex module body. In this configuration, two duplex modules can communicate in opposing directions simultaneously and independently of each other. Depending upon the receiver circuitry used, links of 2 km [1.24 miles] or greater are possible.
