ITU-T - G.651.1
Characteristics of a 50/125 μm multimode graded index optical fibre cable for the optical access network
|Publication Date:||1 November 2018|
This Recommendation describes a 50/125 μm graded-index multimode optical fibre cable which is suitable to be used in the 850 nm or 1300 nm region, or alternatively may be used in both wavelength regions simultaneously.
The geometrical, optical, transmission and mechanical parameters are described below in two categories of attributes:
• fibre attributes are those attributes that are retained throughout cabling and installation;
• cable attributes that are recommended for cables as they are delivered.
This Recommendation, and the different performance categories found in Table 1, is intended to support the following related system Recommendations and standards:
• [b-IEEE 802.3].
The characteristics of this fibre, including the definitions of the relevant parameters, their test methods and relevant values, will be refined as studies and experience progress.
