－
Using Auto fiber profiling check and Detection System (APDS*1), the TYPE-71C
recognizes the type of fiber loaded, automatically chooses the correct splice program,
and proceeds to splicing. This mode enables to splice standard SMF (ITU-T G.652),
MMF (ITU-T G.651), DSF (ITU-T G.653), NZDSF (ITU-T G.655) and BIF (Bend
Insensitive fiber, ITU-T G.657). The recognized fiber type is displayed below a fiber
image on the monitor screen.
ATTENTION
・
The recognizable fiber types are Standard SMF, MMF, DSF, NZDSF and BIF.
DSF is recognized as NZDSF.
The fiber detection is conducted on left and right fibers individually. Even if left and
right fibers are recognized as different fiber types in the result of the fiber detection,
the splicer automatically proceeds to splicing. To double check the results of the fiber
detection, set “Arc Pause” to ON beforehand.
The data on representative core profiles of standard fiber types are stored in the
TYPE-71C. However, other manufacturers’ and new design fibers may sometimes be
recognized incorrectly. In this case, please select suitable splice program by yourself.
・
Even the fiber is the same category such as NZDSF or BIF, sometimes the suitable
splice program is different depending on the manufacturers or fibers. In this case,
please select suitable splice program by yourself.
In the Auto mode, TYPE-71C analyzes the arc and has the function to calibrate the arc
condition automatically at each splice. Therefore, arc test is not needed usually in the
Auto mode.
Perform an arc test in the following situations to calibrate the arc power and
position.
•Poor splice performance (high or inconsistent splice losses, poor splice strength)
•After electrode replacement
•Extreme changes in temperatures, humidity or air pressure
Recent －
The splice program selected recently is listed.
SM
G652
SM G652 Std.
Can be used for splicing identical standard SMF (ITU-T G.652).
SM G652 Quick
Can be used for splicing identical standard SMF (ITU-T G.652) and making a faster
splice. In this mode APDS is disabled.
SM G652 AIAS
Automatic Intentional Axis Shift function (AIAS*2) enables to splice identical standard
SMF (ITU-T G.652) with high core-cladding eccentricities.
Other SMF
The splice programs that include standard SMF are listed. ex)SMF-DSF
SM
ATTN STD
This mode can be used for splicing fibers by shifting the centers of the left and right
fiber cores and achieving intentional high splice losses.
Recommended target attenuation range: 0.1~5.0dB
An estimated splice loss displayed in the splicer may not match an actual splice loss
depending on the fiber type being spliced. It is recommended that actual splice losses
be measured and checked with a power meter.
 ATTN: Enter a target splice loss in “Function” settings (6/6 page). User settable
attenuation range is 0.1~15dB (in increments of 0.1dB).
 ATTN factor: If the target splice loss does not match an actual loss, modify this value
in “Function” settings .
SM
ATTN WIDE
Recommended target attenuation range: 5.0~15.0dB
Refer to “SM ATTN STD” regarding how to use this mode.
