G652D and G657A2 specifications refer to the glass and cable construction of optical fibre and are generally the fibres of choice in optical fibre patch leads for singlemode systems.

1.G652D fibre Mode Field Diameter is 10.4µm @1550nm.

2.G652D fibres provide marginally lower loss transmission, which is better in facilitating long distance communication links (up to and greater than 100km).

3.Shortcoming, G652D fibres have limited bend resistance.

G657A2 fibres are used in advanced access cable network installation, where higher bend resistance is required for smaller cable jointing pits and also allows for cable and hardware miniaturisation.
1.G657A2 fibres are fully compatible with G652D fibres. The G657A2 fibre Mode Field Diameter is 9.8µm@1550nm. Splice losses are slightly higher when splicing the two different fibres together.

2.G657A2 fibre have greater resistance to bending (macrobend) losses (see figure below), and facilitating low cost deployment techniques.

      Therefore, G657A2 optical fibre in patch cords, provide an improved bend radius and flexibility, which may allow for better cable management and routing in congested areas. The improved bend radius, may also allow for increased density in high density patching fields. G657A2 optical fibre is becoming very popular in Data Centre and Enterprise network deployments.
