Introduction
Core alignment fusion splicer FSM-50S with
PAS technology is designed for splicing many
types of optical fibers. It is small in size and
light in weight, making it suitable for any
operating environment. It is easy to operate
and it splices fast while maintaining low
splice loss. In order to achieve the splicer’s
full capabilities, read the following important
information.
Splice mode
The splice mode [SM] is the fastest mode in
the FSM-50S. It completes a fusion splice
after 9 seconds. However, the [SM] mode
splices only standard SM fibers (ITU-T
G652). It cannot splice Non-Zero
Dispersion Shifted Fibers (ITU-T G655) at
low splice loss. Fujikura recommends
using [AUTO] mode when longer splice
time is acceptable for the following
reasons:
(1) When selecting [AUTO] mode, the splicer analyzes the fiber profile, and
determines the fiber type. Next, it loads the proper core observation methods and
arc conditions. Then it completes the splice. The [AUTO] mode can splice all
types of fibers, such as SMF(G652), NZDSF(G655), MMF(G651), etc. The
[AUTO] mode is recommended when the fiber type is not certain.
(2) When using the [AUTO] mode, the automatic arc calibration function is enabled.
It monitors and applies adequate heat power to the optical fiber.
Automatic arc calibration function
This function calibrates the arc power at every splice. Performing the [Arc calibration]
function before a splice operation is not necessary. The automatic arc calibration
function works in [AUTO] mode only. It doesn’t work in [SM], [NZ], [MM], [DS],
[SM-SM] and other splice modes. When using those modes, performing [Arc
calibration] before splicing is strongly recommended.
