Measuring Channel Outputs and Channel Budgets

Channel module outputs, measured at entry to the MUX, point B, or exit of the DMX, point E, are practically constant for all channel cards, whereas measurements at the exit of the BSM (point C) or entry to the BSM (point D) can exhibit a variation of 0 to 2 dB.

Note All power measurements must be done in-line because of ALS.

All measurements concerning budgets need modulated light. We recommend using an external modulated light source. Practically any low powered light source with roughly 100 MHz modulation can be used. If a need for an approved light source exists, contact your Cisco representative.

You need:

•A Cisco Metro 1500 series system

•Access to two Cisco Metro 1500 series systems under test already connected through optical fibers and RSMs (or fiber spools) depending on system configuration

•A short fiber jumper

•Access to ocmstate

•An optical power meter connected in-line through an optical coupler or an optical in-line power meter

If you have an external 100-MHz modulated light source, follow Steps 1 to 3 to measure channel output at point F:

Step 1 Pick a pair of channel modules preferably without clock (or with a clock that can be disabled with the ocmstate command, since none of the currently delivered clocks will match).

Step 2 Connect the light source output to the connector labeled L/R (local receiver) of the local channel module. As a result, the green LED of the local receiver of the channel module is on and the ALS starts working (every 10 seconds the LED for remote transmitting blinks shortly). However, the signal does not get looped back yet.
