TIA Publishes New Fiber Optic Test Procedure - new rules for the industry - Brief Article

Fiber Optics Business, Dec 15, 2000

The Telecommunications Industry Association (TIA) has published a new standard, FTOP [Fiber Optic Test Procedure] -- 197, Differential Group Delay Measurement of Single-Mode Components and Devices by the Differential Phase Shift Method, TIA/EIA-455-197.

The test procedure measures the polarization-sensitive differential group delay (DGD) of one or two port single-mode fiber components over the 1.0 to 1.7 micrometer wavelength range. The DGD at each particular wavelength is determined from the DGD (phase shift) between the orthogonal polarizations. The FOTP does not apply to components that have in excess of 10 dB of polarization dependent loss.

TIA/EIA-455-197 was created by TIA's FO-6.3 Subcommittee on Fiber Optic Interconnecting Devices.
