W&T Plastic Fiber Optic Interfaces and Tools Qualified personnel The product described in this manual may be installed and placed in operation only by personnel who are qualified for the respective task. In addition the documentation for the respective task must be followed, especially the safety and warning notes included in it.
W&T Plastic Fiber Optic Interfaces and Tools Safety instructions General precautions This manual is intended for the installer of the described devices and must be read and understood before beginning any work. The devices are to be installed and placed in service only by an electrical specialist.
W&T Plastic Fiber Optic Interfaces and Tools Electrical safety WARNING If an additional power supply is used, it must provide safe isolation of the low-voltage side from the supply network in accordance with EN60950-1 / EN62368-1. In addition, the power supply must have an LPS feature.
9V, or to use fiber optic interfaces with their own power supply (such as our model 81201). The specified minimum distance of 5 meters for the 81009 Interface only applies if the Interface is operated on an RS232 port with high output levels.
For reliable optical data transmission even in humid environments, the length of the POF cable should not exceed 50 meters for the 81009 model and 70 meters for the 81025/81026 models. For larger lengths, glass fibre should be used to ensure long-term...
W&T Plastic Fiber Optic Interfaces and Tools Interface RS232 <> Plastic Fiber Optic The W&T Plastic Fiber Optic Interfaces, type 81009, 81025, 81026 and 81029 permit bi-directional transmission of RS232 signals by the means of duplex plastic fiber optic cable.
The fiber optic connection for the interface is configured as a self-locking coupling for duplex plastic fiber optic, with the RS232 interface formatted as DB9/DB25 connector. Refer to the following table for connector pin assignments: Pinout RS232 <> POF interface, model 81009 and 81029 pin# RS232 signal data out...
W&T Plastic Fiber Optic Interfaces and Tools Assembly Connecting the plastic fiber optic cable to the W&T Fiber Optic Interfaces requires no special tools: • Trim the fiber optic cable to the desired length using a sharp knife and separate the individual duplex conductors back from the cut point to a distance of around 2 cm.
W&T Plastic Fiber Optic Interfaces and Tools Cutting tool for plastic fiber optics, Model 81600 The 81600 cutting tool enables fast and precise trimming of duplex POF cables size 4.4 x 2.2 mm without the necessity of grinding or polishing the resulting cut surfaces. Background information For short runs it is generally sufficient to trim the plastic fiber optic cable using simple tools such as a sharp knife.
W&T Plastic Fiber Optic Interfaces and Tools Preparing the cutter The plier is shipped from the factory with a safety lock which must be removed before using the tool. Cutting fiber optic cable Open the plier by pressing the two grips on the tool together and then releasing them.

W&T Plastic Fiber Optic Interfaces and Tools A firm pull with the index finger quickly and cleanly cuts the fiber optic cable. To remove the cable from the clamping block, open the plier. With each cutting operation the cutting wheel rotates forward by a slight angle, thus significantly increasing the service life of the tool.
W&T Plastic Fiber Optic Interfaces and Tools Stripping fiber optic cables In addition to the cutting function, the plier is also capable of stripping duplex fiber optic cable. This function is now required however when using fiber optic cable together with W&T fiber optic interfaces.
W&T Plastic Fiber Optic Interfaces and Tools Technical Data Functions: Cutting and stripping fiber optic cables Compatible media: 2.2 mm Simplex- and 4.4 x 2.2 mm Duplex fibers with 980um fiber core Dimensions: 200 mm x 80 mm x 50 mm Weight: 520 g Included:...
