Optical fiber cable placement in the zNID fiber tray
Using a fiber tray involves routing the optical fiber around the spools, then
physically to the SC connector in the zNID.
Note: Sharp bends in fiber cables create undesirable optical
attenuation or loss. The zNID enclosure provides fiber spools and
hooks to avoid sharp bends in the fiber cable. A minimum bend radius
of 30 mm (1.2 in) is recommended for stripped fiber.
To place the fiber cable in the fiber tray:
1 Inspect and clean the fiber connector to ensure it is free of impurities.
2 Make sure the fiber segment is properly installed in the fiber tray, excess
cable is wrapped around fiber reels without having improper bends
leaving enough loose cable so that it will not take too sharp of a bend to
connect to the zNID.
Figure 10: Maintain the proper bend radius in the fiber
3 Test the fiber cable to verify clean signals.
Note: It is recommended that the fiber cable be tested before
finishing.
