Testing Standards for 4-Core Single-Mode Optical Cables

1 is the cornerstone, offering definitions and test methods for linear and deterministic parameters of single-mode fibers. All three fiber types are characterized as “ low‑water peak ”, meaning the maximum attenuation requirement at 1383 nm is equivalent to the maximum attenuation specified at 1310 nm. This constraint eliminates the concern that the fiber will have high loss in the 1360 nm to 1460 nm band caused by OH.
