Optical fiber is the most advanced transmission medium in the telecom sector and the only transmission medium capable of supporting next-generation services. The main advantages of having the last mile of an optical fibre network are many like higher bandwidth, long distances from the centre to the subscriber end, optical fiber is more resistance to electromagnetic interference, increased security, and reduced signal degradation in the transmission. FTTH networks are based on point-to-multi-point type configuration.FTTH technology involves the introduction of fibre optics in the global network, both the backbone network operator and the last mile.
In Passive Optical Network (PON), optical splitters play an important role in Fiber to the Home (FTTH) networks by allowing a single PON interface to be shared among many subscribers. Optical Splitters are installed in each optical network between the PON Optical Line Terminal (OLT) and the Optical Network Terminals (ONTs) that the OLT serves. During the deployment of fiber to the home passive optical network, usually, we will face some physical access network design problems. The other article may help you solve FTTH splitting lever and ratio design problems.
One of the best ways to express the operation of a splitter is with the below figure, you can easily understand the FTTH splitter with the help of the above figure.
Choosing the right FTTH splitter is the first step to starting the splitting level and ratio design. There are two types of optical splitters in our current FTTH network design—PLC splitters and FBT splitters. The differences between these two optical splitter types determine which one is more suitable for FTTH networks. Here is a simple comparison of them:
With the rapid growth of FTTH worldwide, the requirement for larger split configurations (1×32, 1×64, etc) in these networks has also grown to serve mass subscribers, since PLC splitters offer very accurate and even splits with minimal loss in an efficient package, they offer a better solution for today’s FTTH networks than FBT splitters.
