Product Description
Section 1 Product Overview
G.657A1 Single Mode Bare Optical Fiber (ITU-T B6.a1)
G.657A1 bend-insensitive bare fiber is designed for FTTH access network, with excellent macro & micro bending resistance, fully compatible with G.652D standard single mode fiber. Operates in full band 1260~1625nm (O/E/S/C/L band), ideal for tight routing, indoor wiring, small-diameter cable production and optical component manufacturing.
Section 2 Core Features
✅ Ultra-low macro bending loss, minimum bend radius 10mm
✅ Standard geometry: 9μm core /125μm cladding /245±10μm coating
✅ 200kpsi proof test screening, high tensile fatigue resistance
✅ Easy stripping coating, stable stripping force 1.3~8.9N
✅ Low PMD, suitable for high-speed long-distance transmission
✅ RoHS, CE, ISO9001 certified, environmental UV curable coating
✅ Custom length & OEM packaging & label service available
Section 3 Application
- FTTH / FTTB / FTTP access network indoor wiring
- Loose tube, tight buffer, ribbon optical cable production
- Pigtail, patch cord, splitter, coupler optical component
- Metro network, access distribution cabinet wiring
- CATV, intelligent building, security communication system

Section 7 FAQ
Q1: Is G.657A1 compatible with G.652D fiber?
A: Fully compatible, can be spliced directly with standard single mode fiber.
Q2: Can you supply customized length?
A: Yes, we can cut any required length with negotiated MOQ.
Q3: What is the bending advantage of G.657A1 vs G.652D?
A: G.657A1 supports 10mm small bend radius, nearly no extra loss after repeated bending, perfect for narrow space wiring.
Q4: Can you provide test report for each spool?
A: Yes, each reel comes with factory attenuation & geometry test certificate.
