Frequently asked questions
What is the difference between GTQT and GTQ series?The GTQT series is specifically designed for FttH applications and features a re-openable design. The GTQ series is a general gel connection muff suitable for various cable types but not specifically designed for fiber optics.
What does 're-openable' mean for connection muffs?Re-openable muffs can be opened again after installation to inspect, maintain, or replace cables without destroying the entire connection. This is especially important for maintenance work.
What cable cross-sections are available for GT connection muffs?GT connection muffs are available for various cable cross-sections, e.g., 1.5–10 mm², 10–25 mm², 25–50 mm², and larger. The exact size is specified in the product name, e.g., GT-A2 for 4x16–5x16 mm².
