Duplexers send fibre data both ways

HOD Series fibre optic duplexer modules are suitable for demanding, high-performance applications like fibre optic security, systems, datacommunications, remote sensing and control and test equipment.

HOD Series fibre optic duplexer modules are suitable for demanding, high-performance applications like fibre optic security, systems, datacommunications, remote sensing and control and test equipment.

Honeywell developed the products from proven military designs to provide measurable performance superiority.

HOD Series duplexers provide a means of two-way data transfer over a single fibre cable, delivering significant savings by reducing the installed cost of a fibre network.

Cross-talk immunity is up to 40dB, minimising data corruption.

The industry standard footprints allow ease of design, and the customised configurations solve customer-specific needs in industrial sensing, aerospace, oil and gas, smart civil structures, utilities and power generation applications.

"HOD Series duplexers present significant cost savings, minimum data corruption and measurable performance superiority to our customers", said Ian Anderson, Product Support Manager.

"In addition, our ability to customise solutions can solve virtually any customer specific needs".

Honeywell duplexer modules support three application/configuration types: wavelength division multiplexing (WDM), wavelength division (WD) combiners/splitters and active couplers.

The WDM type is full duplex over a single fibre.

Module one contains an 850nm emitter and a 1300nm detector, whereas module two contains a 1300nm emitter and an 850nm detector.

WDM applications are CCTV/video surveillance, datacommunications and remote sensing and control.

The WD type consists of two signals sent simultaneously in the same direction over a single fibre.

Modules one and two both contain an 850nm emitter and a 1300nm detector.

WD applications are light source meters and datacommunications (doubling bandwidth).

The active coupler type is half duplex over a single fibre (bidirectional, but not simultaneously).

Modules one and two both contain an 850nm emitter and detector.

Active coupler applications include datacommunications, remote sensing and control and fibre loop back.
