Connect the standard MT-RJ jumper J3 (has pinless MT-RJ plugs at each end) to the adapter (which contains the pinned jumper J2) and to the MT-RJ jack at the other end of the system under test. Figure 2 3. Connect the MT-RJ jumpers to the adapter. 3. Run the system test, and record the power values. Calculate the link loss by subtracting those power values from the reference values previously taken. The resulting system attenuation should be less than or equal to the system losses allowed by Telecommunications Industry Association/Elec- tronic Industries Alliance (TIA/EIA)-568-B.1, Commercial Building Telecommunications Cabling Standards--Part 1. Refer to Figure 5. The fiber type determines the mandrel diameter. NOTE 62.5/125 IEC and TIA/EIA Refer to Figure 3. i 4. Depending on the test equipment being used, record the two power values (in dBm), one in each direction, or zero the meters. These values are the reference values for subsequent testing.
