Fibre Products & Optical Devices

Castle Microwave is now able to supply industry-leading fibre-optic interconnects, components, and test equipment solutions.



A wide range of fibre-optic connectors is available, including standard SC, FC, and ST types. Innovative small form factor designs including LC, MU, MPO, and MT-RJ, along with field installable and IP rated connectors for outdoor/military applications, are also offered. Accessories include flex boots to provide strain relief for installations requiring cable bends to 90 degrees.

For fibre-optic cable termination, we offer polishing, inspection, and cleaning tools to ensure effective termination and optimum cable assembly performance. Pre-terminated assemblies can also be supplied, including ruggedized assemblies for harsh/military environments.

Other products available include optical attenuators, terminators, splitters, switchable adapters, switches, PM isolators, PM circulators, PM couplers, WDM solutions, and EDFAs.


Test Equipment

For test applications, we supply test and measurement equipment for the optical communications industry that enables maximized network performance by conducting critical measurements such as OTDR, chromatic dispersion, polarization mode dispersion, loss, and optical return loss.


OTDR – Optical Time Domain Reflectometer: fast and highly accurate measurements of optical fibre with a unique range of handheld, benchtop, and OEM module solutions. Equipment is also available for testing submarine cables up to 12,000 km in length.


Optical Loss Test Set/Light Source/Optical Power Meter: superior accuracy and reliability for evaluating a wide range of optical devices and systems, including WDM systems.


Optical Spectrum Analyser: the benchtop analyser features a wide dynamic range, high resolution, fast sweep speeds, and additionally supports multi-mode fibre input.


Accessories: tools required to install and maintain optical networks including standalone Visual Fault Locators (VFLs), Fibre Identifiers and Bare Fibre adapters
