Start with the installation
Access networks often involve tight routes inside buildings and enclosures. Specify the finished cable construction and its minimum installation bend radius before choosing a fiber. A fiber macrobending test is not a universal cable installation limit.
Compare the source conditions
The supplied BendCom G.657.A1 datasheet specifies no more than 0.25 dB macrobending loss at 1550 nm for ten turns at a 15 mm radius. The Nanfang manual lists tighter bend-test conditions for its A2 and B3 products. Compare wavelength, radius and turn count together rather than comparing a loss number alone.
Confirm coating and compatibility
Standard and reduced coating diameters support different cable designs. Confirm the exact coating tolerance, mode field diameter and splice compatibility before accepting a substitution. The source documents contain some different coating values, so request a written specification for the offered grade.
Prepare your inquiry
Include the fiber grade, coating diameter, volume in fiber-km, required reel length, destination and any qualification documents your project requires.
