Review these reminders and warnings before you inspect and clean your fiber-optic connections

Reminders
 Always turn off any laser sources before you inspect fiber connectors, optical components, or bulkheads.
 Always make sure that the cable is disconnected at both ends or that the card or pluggable receiver is removed from the chassis.
 Always wear the appropriate safety glasses when required in your area. Be sure that any laser safety glasses meet federal and state regulations and are matched to the lasers used within your environment.
 Always inspect the connectors or adapters before you clean.
 Always inspect and clean the connectors before you make a connection.
 Always use the connector housing to plug or unplug a fiber.
 Always keep a protective cap on unplugged fiber connectors.
 Always store unused protective caps in a resealable container in order to prevent the possibility of the transfer of dust to the fiber. Locate the containers near the connectors for easy access.
 Always discard used tissues and swabs properly.

Warnings
 Never use alcohol or wet cleaning without a way to ensure that it does not leave residue on the endface. It can cause damage to the equipment.
 Never look into a fiber while the system lasers are on.
 Never clean bulkheads or receptacle devices without a way to inspect them.
 Never touch products without being properly grounded.
 Never use unfiltered handheld magnifiers or focusing optics to inspect fiber connectors.
 Never connect a fiber to a fiberscope while the system lasers are on.
 Never touch the end face of the fiber connectors.
 Never twist or pull forcefully on the fiber cable.
 Never reuse any tissue, swab or cleaning cassette reel.
 Never touch the clean area of a tissue, swab, or cleaning fabric.
 Never touch any portion of a tissue or swab where alcohol was applied.
 Never touch the dispensing tip of an alcohol bottle.
 Never use alcohol around an open flame or spark; alcohol is very flammable.

Best Practices
 Resealable containers should be used to store all cleaning tool, and store endcaps in a separate container. The inside of these containers must be kept very clean and the lid should be kept tightly closed to avoid contamination of the contents during fiber connection.
 Never allow cleaning alcohol to evaporate slowly off the ferrule as it can leave residual material on the cladding and fiber core. This is extremely difficult to clean off without another wet cleaning and usually more difficult to remove than the original contaminant. Liquid alcohol can also remain in small crevices or cavities where it might re-emerge.

What is Fiber Optic Patch Cord

A fiber-optic patch cord is a cable that connects devices to allow information to pass between them. Patch cords are a common way of setting up wired connections between devices, such as connecting a television to a digital cable box using coaxial cable. These cords are used for any type of signal transference, such as in a television, radio or computer network. A fiber-optic cord is a special kind of cable that uses light to transfer signals at extremely high speeds with very little degradation. As a result of these properties, a fiber-optic patch cord is typically a reliable way to transfer information.Most modern homes are full of patch cords, as they connect stereo components,

Notes of using Fiber Optic Patch Cords

1.  Before use the fiber patch cord, we should use the alcohol and absorbent cotton to clean the optical fiber ferrule and its’ end face. 2.  If the connector is dirty, we should clean it by using the alcohol and absorbent cotton, or it will affect the communication quality.3.  The fiber optical modules at two ends of the fiber patch cord must support the same wavelength, in order to ensure the accuracy of data transmission.4.  Don’t excessively bend and circle the fiber, which will leads to an increased decay in the transmission process of the light. The bend radius must be less than 30mm.5.  After using fiber patch cord, we must use protective sleeve to
