Frequently Asked Questions: ConnectorsCN1. What is anaerobic adhesive and can it be used with all connectors?Anaerobic adhesive is a two-part epoxy that will cure when the adhesive and activator are combined. The adhesive is injected into the connector ferrule and the fiber is dipped into the activator before insertion in the ferrule. A complete cure takes less than one minute. There are no curing ovens or lamps required with this type of adhesive; therefore, no electricity is necessary and less time is needed to set-up for an installation. Anaerobic epoxy should ONLY be used with connectors approved for its use. Anaerobic adhesive should only be used with connectors that have a ceramic ferrule and a metal ferrule holder. The following is a list of Corning Cable Systems connectors that can use anaerobic epoxy.
CN2. Can fiber optic connectors be directly terminated onto 250 µm fibers? No, it can be done ONLY with the use of a furcation (fan-out) kit. Loose tube cables typically contain fibers with an outer diameter of 250 µm, which is too small to adequately support a connector. A furcation kit, such as the buffer tube fan-out kit, will add a 900 µm OD protective tubing around the 250 µm fibers. This protective tubing will provide strain-relief and support for the connector. CN3. Can an FC connector be connected to an SC connector? Yes, there are two methods for connecting two connectors of different types. To directly connect them you will need a hybrid connector adapter. An FC/SC adapter will accept an FC connector on one side and an SC connector on the other side. Both connectors should be flat polished for this method to work. If you must connect angled connectors, the second method MUST be used to prevent damage to the connectors. The second method uses a hybrid jumper and two connector adapters. A hybrid jumper is a cable with two different connectors on each end. These connectors should match the two connectors that you want to connect. This will allow regular connector adapters to be used in the patch panels to connect the system. This method does add one extra connector pair loss to the system budget. CN4. How do I test Single-Fiber Connectors? The single most important test of an installed link is end-to-end attenuation. This is a measure of the optical power loss between cable termination points. Click here for the complete procedure. CN5. How do I test MT-RJ Connectors?
