Why can't you splice fiber just anywhere? Where can it be spliced? IF you had a 2,000' run how much "extra" would you add...in your opinion? Thanks,.
For a typical 2000' run:
1. 2,000 foot run (assuming [always a bad thing] accurate measures: 2,000'
2. Termination at one end: 40' x 40' termination room with floor access to the cabinets: 120'
3. Termination at other end: field cabinet: 20'
4. Add 10% 220'
Total: 2,350'
As to the assumption in #1, I do what Jhaney mentioned to get the original length figures, always measuring several times, and ordering once.
This is actually how we do it.
In the termination room, when I'm done, the cable will enter at one point, neatly make its way under the floor to the opposite side of the room, and then go at right angles with appropriate bends to the cabinet it needs to arrive at, where another 30 feet will be coiled at that point and then it will enter the cabinet. Hope this helps you understand the process.
