TIA568 Wiring Standards
How to decide which wiring pattern to use:
1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.
If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

XL fiberTOOLS™ Series
Professional Fiber Optic Instruments
Fiber Optic Visual Fault Finder
Find Trouble in Fiber Cabling or Connectors
Easy Fault Locating
The 170XL visual fault locator is an indispensable tool for quickly identifying bending losses and breaks in optical fibers. If a fiber is bent too tightly, red laser light will be seen escaping through the cable jacket. Likewise if a fiber is broken, escaping light will be visible where the break is located.
Identifying Bad Connectors
Connectors are easily tested using the 170XL visual fault locator. A fiber broken inside or past the ferrule will cause it to glow. If the whole connector glows, it is a defective connector. If the end face polish of the connector is bad, light will be reflected internally.
Features
- Continuous wave output mode for steady fault location
- Find breaks to 3km
- Blinking output mode increases viewing contrast
- Easy-to-use quick interface fits all 2.5mm connector interfaces (FC, SC, ST)
- 1.0mW output power
- Ergonomic rotary switch permits easy one-handed operation
- Rugged, compact and splash proof aluminum design
- Two AA batteries provide 48 hours continuous operation
- Nylon belt holster included
