❶ The first number (1 to 4) identify the link (same reference on back-side connectors).
TX or Rx if that link has a laser transmitter or a receiver, respectively.
The last number after the dot, 51/53/55/57 refers to the CWDM link frequency: 1510/1530/1550/1570nm.
❶ ON/OFF status of specific link
❶ There are 3 possible modes:
o ANT as remote antenna link
o IFB as remote intercom link optimized on a 0dBm reference input
o <n>ifb as remote intercom link optimized for <n>carriers
❶ on TX opt. modules (i.e. 1 TX.51) ANT configuration there are several bandwidth configuration according to
the filter installed in the MFL (see filter option)
❶ Pushing on lower right button the last column shows:
o CUR/PWR show the RF/optical power in reception or the laser current in TX module
o RF LEV shows the value of the RF power level
o “GAIN” that is the relative gain of the link. Here it is possible to change the gain in the operating range.
NOTE: unless you have special needs we recommend to keep GAIN to 0 dB and enable the optical power
correction on the receiver side, since this is already optimized for most applications!
