Power Meter and Light Source
-Now with Protective Rubber Boots

This product range offers the complete solution necessary for the installer to test, terminate and trouble shoot fibre optic systems. The OLK51 series is designed to allow testing of all parameters of fibre optic networks, including output power levels from the fibre, coupled source power and attenuation loss in a cable. Power Meters and Light Sources may be purchased individually or in kits; the table below gives examples of the multimode and singlemode kits with links to the individual component specifications.

We offer complete test kits for both multimode and singlemode applications. The OLK51-MM is designed for multimode use and the OLK51-SM is for singlemode use. The power meter has a modular adaptor port that will accept a wide range of connector adaptors; the source has a fixed adaptor port, ST for multimode and a choice of ST, SC or FC for singlemode. Launch cables are required for making power meter measurements and these are not included with the basic kit, as users generally have their own preferences for length, fibre size and connector styles. These custom made assemblies are available from Tech Optics.

Power Meters

OM120

The OM120 Fibre Optic Power Meter is calibrated at 4 wavelengths (850nm, 1300nm, 1310nm and 1550nm) to +/-0.2dB of the NIST standard for each wavelength through the dynamic range of the meter. The OM120 is designed to measure loss (attenuation) and output power of both multimode and singlemode systems. The OM120 1mm germanium detector is potted in a threaded housing for versatility and allows the user to interchange adaptors for numerous connector types. Power meters with a larger area detector diode are available for special applications, such as when using 200 micron core optical fibres. Contact Tech Optics for details.

OM220 (Data Storage)

The OM220 has the same high performance as the OM120 with the added advantage of user selectable choice of 0.1 or 0.01 resolution, an on-board memory and a serial port connection for communication with a PC or lap-top computer. Computer software is included with the meter for easy documentation of test results. The OM220 is supplied calibrated at 4 operating wavelengths, 850nm, 1300nm, 1310nm and 1550nm, to +/-0.2dB of the NIST standard for each wavelength through the dynamic range of the meter. The meter operates with a 2mm diameter germanium photodiode potted in a threaded housing to allow modular connector adaptation
