AN-104 MTP-MTP Insertion Loss and Return Loss Testing with OPL-MAX

AN-104 MTP-MTP Insertion Loss/Return Loss Testing with OPL-Max

Overview

There are three methods to measure an MTP-MTP patch cord. The first involves using the large area detector or integrating sphere on the OP930. The second method uses a launch and receive cable and reference insertion loss individually per channel through an OP710 Multichannel Power Meter. The third method is a combination of the two where insertion loss is referenced to the large area detector or integrating sphere and the test measurements are taken individually per channel using the OP710.

AN-101 Bar Code Scanning

AN-101 Bar Code Scanning

Overview

In the fast-paced production lines where fiber optic cables are made, every second saved is a penny earned. In an effort to help reduce production time related to re-typing serial numbers and part numbers, OptoTest has integrated the functionality of a bar code scanner. This application note will briefly describe how to configure a bar code scanner to be used with OPL-MAX.

AN-103 Measuring ILRL for Unlike Connectors Using a Golden Cable and Bi-Directional Return Loss Meter

AN-103 Measuring ILRL

Overview

Testing hybrid cables poses certain difficulties due to the ends having unlike connector types. Typically hybrid bulkheads/adapters are required (SC-FC, ST-FC, etc.) and many times they solve the problem with minor issues. However, in some circumstances hybrid bulkheads will not suffice.

When testing SC-LC cables, such an instance arises. SC-LC bulkheads have high loss and poor repeatability and as such, they should not be used in the testing process. To get around this issue, the golden cable method can be used.

AN-102 Polarity Verification through Loss Testing on Duplex Cables

AN-102 Polarity Verification through Loss Testing on Duplex Cables

Insertion loss (IL) and polarity testing are just a couple of the steps required in the testing of multi-stranded fiber optic cables. IL testing quantifies the amount of light lost through the cables and polarity testing ensures that the correct input is routed to its proper output. Usually these two steps can’t be done simultaneously and require almost twice the time. In the case of duplex cables, the OP815-D—coupled with OPL-PRO and a proper configuration setup—can perform both tests at the same time and effectively shortening the testing process. The example discussed below shows how to combine the two steps into one.
