Usually, when faced with extended optical fiber RF installations, the question arises about which type of fiber connector to use. The apparent mechanical compatibility between some of them may even prevent the network from working. Fiber connectors are named after a combination of two acronyms: One refers to the connector type, the other to the size and finish of the fibre ferrule. The first indicates whether the connector is threaded or has a different type of fixing. The second acronym indicates the fiberâ€™s finish: bevelled (APC_Angle Physical Contact), straight (PC_Physical Contact), with an air gap, etc. For example, the seemingly valid connection of a fiber equipped with an SC/PC male connector to a device equipped with an SC/APC female connector causes the signal to degrade, since the compatibility between both connectors must be at both the fixing mechanism and the finish levels.
Dirt: This affects 95% of optical equipment failures. It is essential to always methodically clean the connectors to be installed, even if they are new.
Yes. Optical fibers are good at withstanding longitudinal strain; however, this is not the case when they are winded over themselves (as a result of incorrect uncoiling). This usually causes premature failures as soon as traction is applied to the fibre. Extracting the fibre form the reel longitudinally is essential.
- Insert the fiber through the threaded plastic cap andthe rubber sleeve.
- Strip the fiber (leaving a length of 20mm for a 250micras diameter and 10mm for the 125micras diameter)At this point, and before cutting the fiber with a high precision cutter (Ref.2323), be sure to clean the unprotected fiber with an isopropyl alcohol wipe (250 and 125 micras)
- Insert the fiber into the connector housing, be sure that the end of the fiber does not touch any part of the device, until it reaches the bottom.
- Close the connector tab (in black), trapping the rubber sleeve (and therefore the fiber).
- Move the connector slide switch (in yellow) to securethe fiber.
- Screw in the plastic cap. Insert the green rectangular cap until it is secured (maintaining the same position as it is received).
