The Sendun SD-9 fiber optic splicer is designed to connect optical fibers. It uses core positioning technology with auto focus. 6 high-speed high-precision motors ensure high accuracy and low loss splices. The quad-core processor allows for quick response to user commands.
Sendun is a brand of the Chinese manufacturer of fiber optic splicers Tumtec. This manufacturer has nearly 20 years of experience in the production of this type of devices, offering models for various purposes. The Sendun SD-9+ model is intended for general use: FTTH connections, all types of connections in LAN networks, CTTV, etc. It allows for permanent connections with low attenuation.
Universal fiber holders ensure comfort and speed of work - they can accommodate 250 μm and 900 μm fibers in a tight or loose tube, as well as patchcord cables and/or DROP cables. The splicer, like more expensive Korean or Japanese splicers, in addition to the automatic mode, offers 41 splicing programs, which in certain cases can provide better results - e.g. a program for splicing G.652D fibers with G.657.A1/2 fibers, etc. .Advanced users can create their own presets.
Splicing programs designed for various fiber splicing scenarios, along with the ability to edit their parameters, are rare in devices of this price range. For example, the SM-BI program means combining standard single-mode (SM) fibers in the G.652.D standard with G.657.A fibers (BI - Bend Intensive). An interesting fact is the program for creating an attenuator - here it is about 2 dB attenuation.
Fully automatic, fast and intuitive operation is possible thanks to the 4.3-inch touch screen with 380X magnification. With an easy-to-use menu graphical user interface (GUI), navigating and performing basic actions is very fast.

People who prefer a standard way of navigating and activating selected functions can use the buttons on the welding machine's housing. The following buttons are available: welding machine on/off switch, navigation button, fiber positioning button, welding button, motor position reset button, and stove on/off button button. The front panel has buttons for operating the optical power meter and the visual fault locator.

The process of splcing and heating the shield may take a total of 16 seconds (5 seconds splicing + 11 seconds heating the shield). This fact may be of great importance when implementing installations with several dozen or several hundred splices. The electrodes allow for approximately 5000 splices. The kit includes an additional set of electrodes.
The innovative and patented new design of the stove with a detachable terminal allows for connections based on SoC connectors: LC SC FC ST. Universal fiber holders allow you to connect multi-mode and single-mode fibers in 250 μm and 900 μm coverage in a tight, semi-tight and loose tube.
Optical power meter and VFL operating window.
The welding machine records details of each weld, including damping and the exact execution time, as well as the parameters of the electric arc and the position of the motors.
The splicer has built-in optical power meter (-50 ~ +26 dBm, 850-1625 nm) and visual fault locator VFL (15 mW, 650 nm). These functions may be useful in verifying the correctness of installations. Both can be activated both from the device menu and through dedicated function buttons on the welding machine housing.

Connectors for the optical power meter and VFL visual locator are located on the side of the device. The SD-9+ battery is equipped with an electronic charge indicator. The charging connector is located in the battery, so it can be charged outside the device. The ability to adjust the welder's belt hook may also be a useful feature. This option is useful in situations where the welder is to work in unusual positions.
The 7200 mAh battery allows to perform up to 320 splicing + heating cycles. The battery charging time is only 3 hours. The design of the splicer allows for a very quick battery replacement (pressing the button on the housing causes it to slide out).

The splicer housing is covered with protective rubber, the splice chamber and furnace covers are made of high-quality plastic. The offered set includes a practical box which, in addition to the splicer, contains all the necessary tools, a power supply and accessories. The design of the box without guides in the lower part ensures comfort of use and more space for accessories. The box itself can serve as a station for the splicer during installation and as a table (thanks to additional elements covering the lower chamber) - e.g. for a knife for cutting fibers.
An important element of the sold set is the 9C+ guillotine equipped with blade autorotation mechanism after each fiber cutting. This ensures even wear of the blade over time and no need to rotate it every few hundred cuts. Additionally, the guillotine has integrated container for fiber shreds and protective plastic case.
