Cleaving optical fibers without secrets – blade adjustment.

Proper preparation of the ends of optical fibers is the basis for successful fiber splicing. Even the best and most expensive splicing machine will not be able to properly connect dirty or improperly cleft fibers. For this reason, care for the cleanliness of fiber optic tools is extremely important.

Optical fibers go into homes - how to join them

Systems based on optical fibers are becoming increasingly popular. General availability of comparatively cheap devices converting electrical signals to optical form and vice versa, combined with the advantages of optical transmission, especially very wide band, galvanic isolation between devices and no problems with implementation of long links, are the main reasons for the wider and wider use of this technology in LANs, analog and IP video surveillance systems, S/MATV installations and even in alarm systems. The latest regulations of the construction law in many countries, e. g. in Poland, force investors and building designers to implement fiber optic installations in all newly built buildings of public and multi-dwelling categories. The installations must be "ready-to-use" independently from the initial utilization factor at the moment of the completion of the construction. Due to these facts, installation companies and installers of "low-voltage systems" must be qualified or have to get qualifications in the field of fiber optics, especially in the practical aspects such as installing and measuring/testing fiber optic systems. It is simply necessary for their success on the market.

How to terminate fiber with ULTIMODE FAST connectors

ULTIMODE FAST quick assembly connectors allow fiber termination with SC connectors without time-consuming gluing and polishing. The procedure does no require "sterile" conditions, because the end face of the built-in fiber fragment has been glued and polished by the manufacturer. The low loss at the level of 0.25 dB is obtained thanks to advanced positioning of the inserted fiber end by V-shaped grooves. The optical gel that is also used in the connectors reduces the effects of an imprecise cut and a possible gap between the end faces of the fibers.
