Optical fiber splicing
2. Basic splicing operation
The fusion splicing is a method of melting and connecting the point of optical fiber
by heat of electrical discharge. Since optimum arc conditions are different depending
on the environments (atmospheric pressure and temperature) and the electrode
conditions (wear-out and accumulation of the glass) and the optical fibers
(manufacturer and SMF/MMF, etc.), an optimum arc condition is essential to achieve
a low splice loss. Please perform an arc test before splicing in a typical splice program
such as “SMF Standard”.
Auto Mode which is incorporated in the TYPE-82C+ automatically analyzes and then
calibrates an arc power at each splice. Normally an arc test does not need
performing. However,
the arc test should be performed in the following
situations.
●
Arc test
Good arc state
Arc Center
Start splicing
The arc center is au-
tomatically adjusted.
The arc power is au-
tomatically adjusted.
Prepare the fiber and perform the arc test again.
Prepare the fiber.
Arc test
OK
NG
The adjusted arc power level is stored even if the splicer is turned off.
•Poor splice performance
(high or inconsistent splice losses, poor splice strength)
•After electrode replacement
•Extreme changes in temperatures, humidity or air pressure
