Whatever happened to fiber-to-the-home?

The early vision of fiber-to-the-home, which promised consumers abundant, ubiquitous and future-proof bandwidth, has remained largely unrealized. The basis for the original vision of FTTH has been overtaken by technological, regulatory and economic shifts.

We believe the realities of today make it unlikely that the major players will build out a network without first seeing demonstrable demand for it. The current climate suggests that only "green-field" developments can be sustained. On the other hand, service and societal changes could accelerate the process, government intervention or subsidization could motivate investment, and business strategies-coming from players without a telecom embedded base to protect-could emerge that would realize the promise that FTTH holds.

Essentially, the vision of fiber-to-the-home was developed to satisfy the perceived need for future consumer applications. Optical fiber, it was argued, would permit high-bandwidth transport, remove bottlenecks as video-rich services were developed, enable upgrades and permit passive multiplexing that would remove remote-powering costs.

Sufficient cable shall be left in the initial cable feed manhole to complete the splice to its neighboring cable and to provide cable slack for future maintenance and racking operations. After all cable has been pulled off the reel and the excess cable figure eighted, the pulling equipment shall be moved from the figure-eight manhole to the end manhole to complete the cable placing operation from the figure-eight coil at the intermediate figure-eight manhole as segment 2.

Before the segment 2 placing operation can begin, the figure eight coil must be carefully turned over (“flipped”) so that the cable that was on the bottom is now on top. This cable coil “flip” will enable cable to be fed off the top of the coil to the far manhole to complete the placing operation.

The final segment of micro-duct will be placed from the figure-eight manhole to the far end manhole. The operation shall be conducted as described above. As always, the encasing conduit, sub-duct, innerduct, or micro-duct must be lubricated prior to the start of any placing operation following the lubrication schedule in Table7 or Table8. Once the placing operation begins, lubrication must continue to be applied to the cable as it is placed.

7.3 Placing Assistance

A placing plan determining pulling locations, including the intermediate assist location should be developed during the pre-survey of the placing project. Figure 10 and Figure 11, show a cable jetting operation with intermediate assist, both manual and automatic. Figure 11- Cable Placement Showing Placement Using Intermediate Assist Engine

An intermediate manhole can be selected as an intermediate assist location. It should be near mid-span and, if possible, the duct section in both directions out from the intermediate assist manhole should be place able in a single operation. The area around the intermediate assist location should be sufficient to stage the ground support equipment (air compressor and hydraulic pump) for the placing operation.

For an automated intermediate assist procedure to be successful, the placing engines (primary and assist engine) need to be coordinated, so compressive forces do not build up causing the cable to buckle or kink. This is a procedure that is difficult to perform safely and should only be attempted by an experience placing crew. If used, the assist equipment manufacturer's instructions must be carefully followed.
