Learn more about fiber optic cable:

In today's terms, applications such as telephony and video-on-demand were to be carried over a B-ISDN universal carrier at OC-3 rates. Proposals included an optical version of the telephony loop (each fiber carrying one house's circuit) to passive optical networks (PONs) with an optical splitter delivering light (and bandwidth) to several optical-network units (ONUs). For fiber-to-the-curb (FTTC), the ONUs served several homes.

In the nearly two decades since the FTTH/C vision was established, however, economic, regulatory and technological forces have frustrated the vision's intended universal implementation.

A number of structural forces have been at work. First, the two major consumer applications-broadcast television and telephony-have nearly opposite characteristics. TV is a largely passive, impersonal entertainment delivered as a one-way service requiring high bandwidth. Telephony is personal communication that requires a two-way symmetric, low-bandwidth connection. As a society, we apparently value communication more than "content" because the cost we pay per bit of information on phone calls exceeds that of entertainment by six or seven orders of magnitude.

Once the cable has been placed, sufficient slack cable should be provided on each end of the cable to enable the splice to be made to the adjoining cable, to rack cable in all manholes to the assist manhole, and to store the standard amount of slack at each splice required by the cable's end-user for maintenance operations. Sufficient slack must be provided in intermediate manholes to rack the cable and sub-duct (either innerduct or micro-duct) along the sides of the manhole, out of the way from harm and still have sufficient slack stored to accommodate the end-users requirements.

All ducts should be plugged at the conclusion of the placing operation. If a cable has been pulled into the duct, the duct plug should be sized for both the ID of the duct and the OD of the cable.

Micro-duct shall be left intact through intermediate manholes during placing and racking, whenever possible unless the micro-duct was removed to enable intermediate assistance or a portion of the cable is branched off the cable route being placed. Typically, a cable coil will be placed in a manhole or hand-hole to provide extra cable in the event of network damage or extra cable for splicing fibers. In certain environments, it may be determined that cable protection for the coiled slack is required due to the threat of rodent damage. If possible, protect any slack coils with split flexible conduit and store the coil in a safe position in the manhole or hand hole.

7.4 Back Feeding Assist to Cable Pulling

Backfeeding is a placing procedure in which the cable feed truck is set up at an intermediate manhole. The entire cable is pulled in two operations. Generally, the longest and most difficult segment is pulled first. Sufficient cable must be pulled out of the first pull manhole to accommodate the splicing operation, racking, and sufficient slack for future maintenance operations.
