Thank you for your comments as I know this is a big setback when people are considering using fiber.
Yes, I do the fiber myself and with a couple tips and tricks, everyone can. I could teach this to a kid in 5 minutes.
There are a lot of misconception surrounding fiber termination; expensive, hard to do, fiber need to be perfect, expensive tools, etc.
I think it is important to put in perspective what we are actually using the fiber for.
I’ve been doing fibers for about 20 years on ROVs and the more advanced system need better quality termination du to the multiple connectors, FORJ (Fiber Optic Rotary Joint), multiple wavelengths etc on the same fiber.
This is not the case here.
We are only trying to pass a bandwidth of 100mbps full duplex. In the grand scheme of things, this is nothing compared to what we could really pass over the same fiber.
Also, we do not have a lot of connectors in the circuit to attenuate the signal past the tolerance of the fiber converter.
Furthermore, the fiber converter can deal with a lot of loss before the signal is lost.
Finally, there are no difference of performance between a professional perfect fiber termination and a mediocre one that lets sufficient light through. (In our scenario)
So, with that in mind, there are 4 major termination methods I’ve used; Holt melt, crimp, splice,fast.
They all have there pros and cons, but in order to keep cost, rapidity and complexity down, I recommend the fast method using LC connectors.
LC connectors are very small, they allow to pass the connector through your end plates. The way I do it is pass it through the threaded part of the 18 hole plate and connect inside the converter. Rotate counter clock 2 turns before I screw it in so it goes in the ROV without any turns.
The fast method allow to use an automatic cleaving tool and does not require epoxy or polishing. Its ready in minutes but its not as mechanically solid a connection as the other methods. That said, I use regular epoxy or hot glue to strengthen the mechanical bond depending on time constraints.
So as far as skills are concerned, if you can measure and thread a needle, you’ll be able to do it…
With regards to quality control, you can use an scope to check the fiber end, an OTDR, fiber light meters and all that good stuff but really, only a lazer light will do. Shoot the lazer at one end and point the terminated end on your hand. If its bright and shooting straight its good enough lol. The difference between a good and a bad termination is very notable.
I can do terminations with a regular 2USD wire stripper and a stanley knife but I will be selling a complete proper kit for about 100USD.
I’ll post a video when I get a chance.
