Is there any provision about using a splice (fusion or mechanical splice) in an Optical Communication System,, like using 1 splice every 2 kilometers of fiber optic cable?
I mean a rule or standardization about using splice in an Optical Communication System (if there is).
But, if you say about precaution, is there a standard for that and what is that (the standard)? And, what is that precaution for?
Thanks.
To Stevan: There are mainly two types of splices used in optical communication systems: Mechanical and Fusion splices. The amount of losses at the splices depends on the quality of the splices that are used. The better quality splices means more cost. Typically fusion splice may be 0.05 dB or even some claimed as 0 dB. To my belief,once you can detect the light power after a splice joint, you are through with your problem. It depends how much cost is tolerable in your system.
The quality of fusion splice lies on the quality of the fusion splicer available in the market. As far as mechanical splices are concerned, there are different versions with different prices in the market with different loss values.
The number of fusion splices at the optical link dependent on the cable (fiber) length. Cable is typically supplied in 2 or 4 km lengths.
Thanks all, I've read from one article in internet that tell me the same as Volodymyr , it depends on the cable length that produced.
What I said is not in conflict with words of Volodymyr and Simon. VIVA
The length of fiber-optic link is usually much longer than the length of fiber-optic cable supplied by manufacturers. Therefore, there is a need in coupling of several cables together to get desired fiber-optic link length. Usually, two types of fiber connections are commonly used: fused and mechanical. To get fused connection you need a special welding apparatus, which is very expensive. But it allows to get connection with low losses. The criteria for fused connection is 0.02dB. If received losses exceed this value than connection must be destroyed and complete coupling process should be repeated. When you get losses
There is no standard about that. It depends on the optical link power budget. You can have as many splice as you want (definitely should be a reliable, minimum loss splice like around >0.02dB) as long as the total budget loss is within the required optical budget of your link. There are standards for optical budgets depending on PON architecture. Your components, fiber optic length and splices contribute to the losses and those are the things that you should consider on how many fusion splices you could use in your link.
@ Julius: You are correct. All the required splices should be engineered according to the total power budget of the link. VIVA
