-splicing programs
-heater programs
-function settings

For more details, please view "Functions" in your operation manual.
Can I add or change a language?
You can change the language from installed languages in your machine. Unfortunately, you can not add new languages.
Can I splice loose buffer fiber?
Yes, you need to use an universal clamp which comes with TYPE-72C/82C.
Can I splice G.652 fiber to G.657 fiber?
Yes, you can. Sometimes it may be necessary to adjust your splice program and to do the arc test.
I have accidentally used a wrong heater program for my sleeve type.
What should I do?
Unless you see non usual outlook on fiber sleeve such as bubbles or unshrunk status in the sleeves, there is no problem and you do not need to re-splice.
What is an appropriate cleave length?
We recommend to strip the fiber coating for approx. 30-40mm.
Please view our Stripping the fiber coating page for more dertails.
Can I use the splicer continuously for long hours?
There is no problem for long hours usage. We recommend to operate with AC power.
Can I use other manufacturers fiber holders with Sumitomo Electric splicers?

A high loss is measured by OTDR. Why?
We recommend to check following steps.
1. Measure wavelengths at 1310nm and 1550nm by OTDR to identify the cause of the problem.If the loss is high both at 1310nm and 1550nm, there may be a problem at splicing part.If the loss is low at 1310nm, but the loss is high at 1550nm, there may be stressed part at optical fiber when you store the fiber in the box/closure. Fiber can be stressed by twisting, bending and pressure.Check and improve fiber storage part.
2. Check if the setting for marker is correct or not in OTDR.
3. Check if you are making bi-directional measurement.
The splicer shows a good estimated loss but OTDR and power meter measurement show a high loss. What should I do?
We recommend to check following steps.
1. Measure wavelengths at 1310nm and 1550nm by OTDR to identify the cause of the problem.If the loss is high both at 1310nm and 1550nm, there may be a problem at splicing part.If the loss is low at 1310nm, but the loss is high at 1550nm, there may be stressed part at optical fiber when you store the fiber in the box/closure. fiber can be stressed by twisting, bending and pressure. Check and improve fiber storage part.
2. Check if the setting for marker is correct or not in OTDR.
3. Check if you are making bi-directional measurement.
The splice shows a good extimated loss (est loss 0.00dB, image ok), but there is red light leaking from the splice point/sleeve when tested with Laser. Why?
There are possibilities one of followings occurs.
-the fiber is not accurately aligned. (actual loss is high)
-the laser light power is too strong.
-fiber is disconnected/ bended / twisted.
How do I ensure that my splicer makes a good splice?
