PC fiber connector was generated to overcome the air gap between two surfaces from small imperfections in the original flat fiber connector. It is the most common polish type that is found on OM1 and OM2 multimode fiber. PC fiber connector refers to the connector that is polished in the physical contact style. There are four connector polish types, three of which will be highlighted below. To increase the efficiency of fiber, engineers began to upgrade the surface of the critical point of attachment, and that’s how ferrule polish technologies are introduced. When connectors are installed on the end of a fiber, light is reflected back up the fiber towards the source, disrupting the signal. The ferrule is the housing for the exposed end of a fiber, designed to be connected to another fiber, or into a transmitter or receiver. To put it simply, PC, UPC, and APC refer to the polish styles of the ferrules inside the fiber optic connectors, just as the following figure shows. A secondary effect is that if the connectors are dirty, it can scratch the end finish (most dirt is silica (sand) based) and cause higher reflectance if not loss.Introduction to Different Connector Types Typical airborne dust is almost the size of the SM fiber core, so cleaning every time is even more important than MM. When testing, we recommend that connectors on both the reference and tested cables be cleaned before every test, as every time the connector is exposed to air, it can accumulate dust. Not only will it prevent additional dust buildup, but it will prevent contamination from being touched or damaged from dropping.Īlways clean connectors before mating, whether for testing or making network connections. We recommend you always keep dust caps on connectors, bulkhead splices, patch panels or anything else that is going to have a connection made with it. Test equipment has fiber-bulkhead outputs that need periodic cleaning, since they may have hundreds of insertions of test cables in short time frames. Network operators claim that 15-50% of all network problems can be traced to dirty connectors causing connection problems.Īirborne dirt particles are about the size of the core of SM fiber and are usually silica based - they may scratch PC connectors if not removed! Patch panels have mating adapters that can become contaminated if left open to the air or scrape off foreign particles under repeated usage. On each of these labels the part number, serial number, and the length of the patch cord are displayed for easy product recognition and traceability.ĭirty connectors are one of the major problems in fiber optics, causing high connector loss, high reflectance and contaminating transceivers. All FiberOptic Supply’ patch cords have an identification label and have a unique serial number assigned to them. FiberOptic Supply offers a wide variety of connector options, jacket colors and diameter as well as different flammability ratings, and have the capability to custom build to meet your most stringent mechanical and performance specifications. The quality of the components used to build our fiber optic patch cords ensures long lasting and high repeatability connections. They are designed, manufactured and tested according to protocol and performance dictated by the industry standards.
