What is the best fiber for FTTH?

What is the best fiber for FTTH? : The question that is often asked is that which fiber is the one of the best for the FTTH network? Whenever this question is asked, only a few friends can answer it correctly. Through this article, it will be told which is the best optical fiber used for FTTH network. 

One thing is very important that the choice of optical fiber is determined by various parameters, the most Significant and restrictive dispersion and optical attenuation. The advantages of single-mode fiber (high transmission efficiency and low optical attenuation) make this medium the most attractive for FTTx networks.

Best options the usage of fibers for FTTH

Apart from the issue of the article, I will not discuss any other topic, I will directly talk about the issue. The only issue in this article is what is the best optical fiber for the FTTH network?

The fact of using single-mode optical fiber in FTTH networks allows access to the rest of the network that already uses this type of fiber, giving it transparency and uniformity.

How many types of Single mode Fiber?

It also simplifies operation, maintenance and development. Therefore, it recommends the use of this type of fiber for FTTH access networks. It can identify as the best option. Use of Fibers G.652D or G.657A and G.657B for FTTH.

New fibers that conform to G.652D standards eliminate water peak attenuation and allow full operation of all 20 channels in metropolitan networks. G.652D defines a full spectrum, low water peak fiber with low PMD and represents the broadest standard for standard single mode fibers.

But private service providers are demanding that cable manufacturers follow G657 standards. This standard describes two categories of single-mode optical fibers suitable for use in access networks.

Category A fibers are suitable for transmission in the O, E, S, C and L-bands (during the 1260 to 1625 nm range). Fibers of this category have uniform transmission and interconnection properties, which is G652D. The fibers are accompanied by better bending losses and strict dimensional specifications.

Category B fibers are suitable for transmission at 1310, 1550, and 1625 nm for restricted distances that are associated with transport in the manufacture of signals. These types of fibers have different splicing and connection properties compared to G.652 fibers, but are capable of much lower values   of bend radius.

Fibers For User

The total number of fibers per end-user or customer is determined by the degree of use of active opto-electrical components that are present on the network. Most point to point systems are based on the use of two fibers per link, one dedicated to the upstream and the other to the downstream. But in this project, and given that it will use WDM technology, the uplink and downlink channels will travel through the same fiber but in different wavelengths. This means that the number of fibers and connectors is cut in half, saving cost and space.
