SR EN IEC 60793-2-10:2019

IEC 60793-2-10:2017 is applicable to optical fibre sub-categories A1a, A1b, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Sub-category A1a applies to 50/125 mm graded index fibre. Four bandwidth grades are defined as models A1a.1, A1a.2, A1a.3 and A1a.4. Each of these bandwidth grades is defined for two levels of macrobend loss performance that are distinguished by "a" or "b" suffix. Those models with suffix "a" are specified to meet traditional macrobend loss performance levels. Those models with suffix "b" are specified to meet enhanced macrobend loss (i.e. lower loss) performance levels. Model A1a.4 supports single wavelength or multi-wavelength transmission systems in the vicinity of 850 nm to 950 nm.  Sub-category A1b applies to 62,5/125 mm graded index fibre and sub-category A1d applies to 100/140 mm graded index fibre. Other applications include, but are not restricted to, the following: - short reach, high bit-rate systems in telephony, distribution and local networks carrying data, voice and/or v
