What is the outside coating diameter of the fiber in tightbuffered cables?

• A. 900um
• B. 800um
• C. 1000um
• D. 1200um

Answer: (A)

Tight-buffered fiber features a single protective coating that brings the overall diameter to about 0.9 millimeters. This 900 micrometers size is chosen because it provides good mechanical protection while still being small enough to handle easily and fit with standard connectors and management hardware. So, the outside coating diameter you’re typically dealing with for tight-buffered cables is 900 micrometers. Other sizes aren’t the standard for this construction—800 micrometers would be unusual for a true tight buffer, and 1000 or 1200 micrometers would be too large for common fittings and equipment.
