WORLD’S NO.1 PERFORMANCE FIBER PATCHCORD

Fiber connectors are widely known as the weakest and most problematic points in a fiber network. XFS proposes “3A+G” as the performance and reliability level for our single mode and multimode fiber optic connectors.

OPTICAL PERFORMANCE

"3A+G" connector has an average random mated insertion loss of just 0.05dB to 0.07dB, exceeding the performance level of IEC 61753-1 Grade B. Its power loss is merely 1.1% to 1.6%, or one-tenth of the level made by most other suppliers.

For Single-Fiber Connectors

Item	Parameter		Reference
Item	Single mode	Multimode	Reference
Insertion loss	IEC 61300-3-34	Random mated average ≤ 0.07dB	Random mated average ≤ 0.05dB	Random mated average ≤ 0.07dB Random mated for 97% ≤ 0.12dB	Random mated average ≤ 0.05dB Random mated for 97% ≤ 0.10dB	IEC 61300-3-34
Insertion loss	IEC 61300-3-34	Random mated for 97% ≤ 0.12dB	Random mated for 97% ≤ 0.10dB			IEC 61300-3-34
Return loss	IEC 61300-3-6	≥ 70dB (APC) ≥ 55dB (UPC)	≥ 45dB	IEC 61300-3-6

RANDOM MATING TEST VS MASTERCORD TEST

Note: Random Mating, a method of cross-mating patchcords from different manufacturers or manufactured batches without the use of Mastercords or adapters, provides the best replication of IL results seen in the field. For most other suppliers, if their patchcord has a 0.2dB IL by Mastercord Test, usually it will have a much worse IL result when their patchcord is tested by Random Mating. Random Mating Test is a much better gauge to differentiate good and bad quality connectors and the only way to guarantee the intermateability with generic patchcords.

END-FACE GEOMETRY

“3A+G” fiber optic connector has a far more strict end-face geometry standard than IEC’s: the radius of curvature, apex offset, fiber height, APC angle and key error have all been effectively controlled for exceptional product consistency and optical performance.

Item	PC (Ref: IEC 61755-3-1)		APC (Ref: IEC 61755-3-2)
Item	2.5mm ferrule	1.25mm ferrule	2.5mm ferrule	1.25mm ferrule
Radius of Curvature (mm)	10 to 15	7 to 15	6.5 to 9	6 to 12
Fiber Height (nm)	-30 to 30	-30 to 30	-30 to 30	-30 to 30
Apex Offset (μm)	0 to 30	0 to 30	0 to 30	0 to 30
APC Angle (°)	/	/	7.8 to 8.2	7.8 to 8.2
Key Error (°)	/	/	-0.2 to +0.2	-0.2 to +0.2

APEX OFFSET

|KEY ERROR|

NOTE: Apex Offset is the distance between the apex of the ferrule’s end-face and the center of the fiber core. Key Error is the angular format of the vertical shift of Apex Offset, which can also represent the testing repeatability of Apex Offset on different test machines. In order to have consistently exceptional optical performance under various scenarios, it is critical to make these two parameters as small as possible.

END-FACE QUALITY

For end-face quality, IEC guidelines allow a few defects that are small in size. “3A+G” fiber optic connector is one of the very few in the industry to deliver connectors with zero defects on the ENTIRE FERRULE END FACE. Thus the connector’s light extraction efficiency is optimized.

Zone	Range(μm)	3A+G		IEC 61300-3-35 ed2.0 (APC)
Zone	Range(μm)	Scratches	Defects	Scratches	Defects
A: Core	0 to 25	None	None	4 ≤ 3μm	None
B: Cladding	25 to 115	None	None	No limit	No limit < 2μm 5 from 2μm to 5μm None > 5μm
C: Adhesive	115 to 135	None	None	No limit	No limit
D: Contact	135 to 250	None	None	No limit	None > 10μm
E: Rest of Ferrule		None	None	No limit	No limit

Zero defects in the Core, Cladding and Adhesive zones

The Contact zone and its edges are also free of defects
