Operation: Manual Measurements; Power Loss - Black Box CertiFiber TS655A Manual

CERTIFIBER™
5. Operation: Manual
All connectors and fiber-end faces need to be clean
prior to testing. Use the appropriate optical cleaning
supplies to keep connectors and adapters free from
contamination.
Both CertiFiber units come with covers on their ST
connectors to protect the connectors from dirt and
other foreign matter. Keep the connectors covered
when the units are not in use. This helps to ensure that
contaminants do not affect test measurements.

5.1 Power Loss

The proper operation of a fiber network can
be affected by the operation of its active
components, such as transmitters and
receivers. Excessive loss could actually be a
result of a transmitter launching light at an
unacceptable power level. Transmitters can also
deliver too much light into the fiberoptic cable,
causing the receiver to overload.
You can use CertiFiber's Power Meter
function to quickly verify and correct cabling
and equipment problems. For both test
wavelengths, Power Meter reports the overall
power, the previously stored reference value,
and the loss.
To perform a Power Meter test, take these
steps:
1. Connect CertiFiber directly to a cable or
use a launch cable to connect to the
equipment to be tested.
