Description
The MLP 4-2 Test Kit offers accurate fiber optic testing at an
affordable price. Combining the OPM 4-2C Optical Power
Meter and the OLS 1-2 Optical Light Source in a rugged
carry case, the MLP 4-2 is a complete Test Kit for fiber
optic LAN's, and WAN's.
Used during installations or maintenance, the MLP 4-2
performs insertion loss measurements on multimode fiber
at 850 and 1300nm, as well as singlemode fiber at 1300nm.
The auto zero feature stores reference values at each
wavelength for direct loss readings in dB.
1 Attach Mandrel to Transmit Jumper
Wrap the transmit jumper five times around the mandrel and attach
it to the output port of the OLS 1 (LED source).
Note: The transmit and receive jumpers must use same fiber type
(50 or 62.5µm) as link.
2 Set Reference (One Jumper Method)
Connect the output of the OLS 1 directly to the input of the OPM 4
(optical power meter). Then press and hold the Ref (set reference)
key until the word “HELD” appears. When you release the Ref
key, the OPM 4 should display “0 dB” (+/- 0.05 dB) indicating
that the power measured at output of the transmit jumper has
been recorded as the reference level for your insertion loss
measurements.
3 Check Jumpers
Disconnect the transmit jumper from the OPM 4 (be sure NOT to
remove the end of the jumper connected to the OLS 1). Attach the
receive jumper to the OPM 4. Mate the free ends of the transmit
and receive jumpers. Verify that the insertion loss of this mated
connector pair is well under 0.75 dB, the maximum allowed by
the TIA. Noyes recommends that the loss of your mated test
jumpers be < 0.4 dB. If not, clean both jumpers and repeat
steps 2 and 3.
4 TestLinks
Connect the OLS 1 and OPM 4 to opposite ends of each link to be
tested. Take insertion loss measurements.
