Figure 9. Connect the Receive Reference Cable

13.Verify the insertion loss of the reference cable pair is less than 0.75 dB, the maximum allowed by the TIA (Extron recommends 0.4 – 0.5 dB).

If the insertion loss (dB) is not within these values:

•Disconnect the transmit and receive cables at the coupler (or bulkhead). Clean the free ends of both cables and both sides of the coupler (bulkhead), then repeat step 11 through 13.

•If the insertion loss is still not acceptable, replace both test reference cables and begin again with step 1 on page 12.

Insert the Link

1.When the insertion loss is acceptable, (< 0.75 dB), disconnect both the transmit and receive reference cables from the coupler or bulkhead.

NOTE: Do not disturb the reference cable connections at the light source or the power meter.
