Fiber Loopbacks
New Zealand engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. This section covers the fiber loopback product line: self-contained test modules in LC, SC, MTP/MPO and MMC interfaces, single-mode and OM4 constructions, with fixed 3dB attenuated options.
For New Zealand backbone projects, ensure the relevant connector gender and fiber count against the transceiver interfaces during design and keep the modules with the test documentation.
Each module is optically tested before packing; state interface, fiber count, polish and attenuation when specifying the purchase.
LC/SC Loopback Modules

How to Specify and Order
Each loopback module is optically tested before packing and ships with its dust cap fitted. When specifying the purchase, refer to this loopback by connector interface, fiber count, polish and attenuation; for other attenuation data, allocation types or connector combinations, send the test requirement with the enquiry and the factory will cross-check the manufacturable specification. New Zealand project orders can include documentation and labeling requirements alongside the technical configuration.
