NOTE

How many cassettes to place on each holder depends on how many feeder and distribution fiber pairs require splicing. If you intend to accommodate 16 (max.) signals from the CO and up to 432 (max.) from the distribution, you need a total of 19 cas- settes: one for the feeders and 18 for the distribution. It’s wisest to arrange cassettes more or less evenly among the holders. It’s also wisest to add all intended cassettes to the stack before running loose tubing and splicing any of the cassettes.

Normally, each cassette holds up to 24 splices. If desired, up to 48 splices will fit each cassette in two layers of 24 — 24 lower and 24 upper. Two layers makes for a crowd cassette, however, but lessens the number of cassettes overall.

16.After completing a stack of cassettes (a cassette pod), check the length of loose tubing required to reach the cassette. The fol- lowing illustrations show the shortest and longest required paths for tubing.

The distance between the feeder cable breakout at the cable entrance and the cassette entrance will vary from 5 to 8 ft (~1.5 to ~2.5 m) depending on the starting and ending points in the cabinet and on the door. Check the distance and add in multiples of 8½ ft (~2.5 m), if desired, and then carefully cut off the excess tubing, being mindful of the fiber strands within. DON’T CUT THROUGH THE FIBER because you will need an additional 3 ft (~1 m) beyond that point for the unprotected strands which will be in the cassette. So, 3 ft (~1 m) passed the end of the loose tubing, cut away the excess fiber.

NOTES

All feeder fiber is in 3-mm, radius-control loose tubing between feeder cable entrance and connectorized splice.

All distribution fiber is in 3-mm, radius-control loose tubing between distribution cable entrance and the connectorized fan out at the patch module.
