Following up on my previous Blog Post — The Crosscoupling Degeneration in Communications — an additional issue that is a Limiting Factor in attaining greater speeds in data transmission in Broadband Communications is the problem with mixing Copper based signals with the pure Fibre-Optic signals.

Well the problem of conversion of optical to electronic signals at different segments of Transmission and having segments that are Copper will be the choke segments or points that result in the reduction of speed.

The Most Optical Configuration at a Consumer’s Point of Service is the following one with the With the Copper and Fibre-optic signals properly BIFURCATED !

a) Leave the Current Copper Line as is — and on that route the Telephone Voice Calls a Pure Voice Line —

b) A Pure Fibre Data Line for the Fibre Optic Broadband — On this Route the separate High Speed Fibre Broadband — on this with pure Fibre Wiring to the last mile.

The Copper Transmission though slow is perhaps better for “Voice Signals Communications” as continuous analog signals, where the speed is of not that much consequence as the DATA Lines for high speeds in the GigaBytes range.

At the same time, currently Consumers have to pay a Line-Rental Fee for each Line !!

So a good Cost-Effective Solution to having Two Line-Rentals is to use The Composite Hybrid Cabling !

A Single Composite Copper-Fibre Cable running from the Exchange Boxes that receive the bifurcated Voice Copper Lines and Fibre-Optic Data Lines to the Last Mile !!

Using the Composite Copper-fibre cabling though a little extra — The Line Rentals could be kept a little bit above a Single Mode Line, and the additional cost amortised in the Service Contracts at the Higher Speed users.

Using composite cabling for the Last Mile in Consumer BroadBand Service Configurations is perhaps a good way to push the current Data Broadband Speed Envelope !!
