Which standard defines the maximum splice loss referenced earlier?

• A. Telcordia GR-20 and GR-765
• B. ITU-T G.652
• C. IEC 60794
• D. ANSI/TIA 568

Answer: (A)

Splice loss is the extra attenuation introduced where two optical fibers are joined, and standards set how much loss a splice may introduce to keep the overall link within the system’s required budget. In telecom practice, the combination of Telcordia GR-20 and GR-765 defines the maximum allowable splice loss and the methods to prove it. These documents lay out the performance and testing requirements for splices and other optical components, providing a concrete limit that ensures reliable link performance across networks. Other standards focus on different aspects: ITU-T G.652 describes fiber types and their characteristics, IEC 60794 covers cable products and their specifications, and ANSI/TIA 568 relates to premises cabling practices. They don’t specify the splice-loss limit in the way GR-20/GR-765 do.
