Sites FAQ

Here are some things to remember about sites and using sites in the Fiber OWL and Micro OWL power meters:

	A site is defined as: a group of fibers that have the same properties (fiber type, fiber length, number of connector pairs, and number of splices).
	A site can be used for any number of fibers, fiber cables, or bundles (groups) as long as they have the same properties.
	A fiber group typically starts in one location and ends in another. It is for this reason that we use the term "site".
	Reference values serve as a baseline for PASS/FAIL measurements that are applied to the fibers associated with a site. The properties of a site are used to calculate reference values. These reference values are stored for each site, and are calculated according to: the loss values associated with the fiber properties (currently using the values stated in the EIA/TIA 568-A); and the power level from the source when the reference is set.
	If you need to test fiber groups bi-directionally, the same site can be used to test in both directions because the characteristics of the groups are the same regardless of direction.
	A composite fiber cable will require multiple sites, since single mode and multimode fibers placed in the same composite cable have different fiber types.
	Site names are user-definable. They should describe the general characteristics of the fibers included in the site.
	Be very careful that you do not change any information pertaining to a site in the meter, especially the reference value, before the data is downloaded. Any change in site information will be applied to all data points saved under that site, even ones that have been previously saved. Download the data stored in the meter to our OWL Reporter software before changing the site information.

Example: XYZ Corp. has 10 identical 24-fiber cables used as an outside plant backbone running between Building A and Building B. These fibers follow the same pathway, have the same length (1.5 km), are 9/125 micron single mode, and have the same number of interconnects (0) and splices (0).

All of these fibers can be included under a single site. A suggested name for this site could be: XYZ-A-B-BBONE.

These links are to be tested against the TIA-568-A cabling standard. This standard specifies testing backbone cables at both wavelengths. In the case of single mode fiber, this would be 1310nm and 1550nm. The standard allows a maximum of 0.5 dB/km for the fiber (both wavelengths), 0.75 dB per connector pair, and 0.3 dB per splice. The reference value set prior to testing is –10.12 dBm.

1.5 km x 0.5 dB/km 0.75 dB

0 connector pair x 0.75 dB 0.00 dB

0 splices x 0.3 dB 0.00 dB

Total Allowed Passive Attenuation 0.75 dB

Reference Value -10.12 dBm

Total System Reference Value for Site XYZ-A-B-BBONE -10.87 dBm

During testing, any reading lower than –10.87 would fail, and readings above –10.87 would pass.
