Installing Fibre Optic Cables in Sewer Ducts

Fibre optic cables are the in-thing for anyone looking for a solution to their data transmission problems. They are top choice for both private and public institutions that require robust security to data theft without compromising speed and operational costs. Typically, fibre optic cables excel at high-speed operation (gigabits), a high carrying capacity and ability to transmit over long distances without requiring a refresh. 

However, you may not be able to install your fibre cables in conventional spaces. Sewer lines, river beds and lake beds make up some of the unconventional places where your cables may have to sit. In this piece, learn about installing fibre optic cables in sewer ducts.

The Categories of Sewer Ducts

There are two primary sewer duct types when you want to install fibre optic cables. The first one is a person-accessible sewer, and as the name suggests, it should be friendly for access by technicians. A diameter above seven-hundred millimetres is suitable for someone to enter and leave the duct safely. On the other hand, there are non-person-accessible sewers that aren't safe for technicians to enter during installation. Such sewer ducts have inherent risks such as collapsible walls or poisonous gases. 

Non-person-accessible ducts require special robots to assist in placing the fibre optic cables. The installation might cost slightly more than the person-accessible ducts, but it worth mitigating the risk and complying to local regulations.

The Methods of Fibre Optic Cable Installation

Undoubtedly, sewer ducts present a new dimension to installing fibre optic cables, and you need unique methods that work for you. The first one features traditional fibre optic cables referred to as micro-cables. They are ideal for fibre optic cabling installation in protective ducts set in place before the technicians lay the actual cables. 

Secondly, the technicians can also go for self-supporting cables capable of staying suspended on the top section of the sewer duct. They are robust enough to withstand the tough sewer environment with no need for added protection.

Lastly, the technicians can armour your cables specially and fit them to the lower section of the sewer ducts. It comes in handy when the first two methods do not optimise the cables' efficiency.

The Benefits

The sewer duct environment mightn't appeal as a good alternative, but it offers some advantages. First, you avoid damaging paved surfaces such as roads and other underground installations. Secondly, most sewer ducts are secluded, and that keeps your fibre optic cable from unnecessary noise pollution that can interfere with data transmission.
