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 Power Meter
Measure Insertion Loss and Optical Power
Do not confuse the small size of the 560XL with its ability to provide powerful results. The optical power meter is the perfect tool for installation and testing of fiber optic cabling. The 560XL can be used to measure optical power or used in conjunction with a LED or Laser source to perform insertion loss testing on multimode and singlemode fiber optic cabling.
The 560XL measures optical power at 850nm, 1300nm, 1310nm and 1550nm. It can store reference levels for faster, more efficient testing. The 560XL uses Snap On Connector interface (SOC) to connect FC, SC and ST connectors.
Features
- Easy to use - three buttons control all functions
- Loss measurements in (dB) power measurements in (dBm)
- 0.01dB measurement resolution
- Multi-wavelength storage - stores and recalls reference power levels for faster, more efficient measurements
- Snap on connector interface adapts to FC, SC and ST connectors
- Long battery life - approx. 100 hours continuous operation
- User selectable auto shut-off
- Rugged and splash-proof
- Economically priced
