G657A1 and G657A2 are both subcategories of G657A single-mode optical fibers, known for their high bending performance and compatibility with G652D fiber optic cables. The primary distinction between G657A1 and G657A2 lies in their bend radius and resistance.
Key Differences Between G657A1 and G657A2:
Minimum Bend Radius: G657A2 has a tighter minimum bend radius of 7.5mm, compared to 10mm for G657A1.
Bend Resistance: G657A1 is designed to withstand tight bends, making it suitable for both indoor and outdoor applications, while G657A2 is mainly used in outdoor settings.
Applications: G657A2 is often favored in high-density patching fields within data centers and tight spaces due to its tighter bend radius.
Due to its smaller bending radius, G657A2 is more suitable for confined spaces, such as corners or FTTH (Fiber to the Home) mini wall outlets and termination boxes. While both are compatible with G652D fiber, G657A2′s enhanced bending performance makes it ideal for environments requiring more flexibility in cable routing. The cost of G657A2 is higher, so choosing the right optical fiber depends on the specific construction environment and project budget.
