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


  1. FTTH / FTTB / FTTP access network indoor wiring
  2. Loose tube, tight buffer, ribbon optical cable production
  3. Pigtail, patch cord, splitter, coupler optical component
  4. Metro network, access distribution cabinet wiring
  5. CATV, intelligent building, security communication system


Section 4 Packaging & Shipping


  • Standard length: 25.2km / 50.4km per plastic spool
  • Each spool wrapped with plastic film, packed in export carton
  • Bulk order: pallet packing for sea freight
  • Lead time: 3-7 days for stock order; 10-15 days for bulk customized order
  • Shipping: DHL/FedEx/Air freight/Sea freight negotiable


Section 5 Certifications


ISO9001, CE, RoHS, IEC60793, ITU-T compliance report, Factory Test Report (FTR per spool)

Section 6 Our Advantage

  1. Factory direct supply, stable raw material from YOFC/Hengtong/Prysmian
  2. 100% full test before delivery, full length inspection report provided
  3. Flexible MOQ, small trial order acceptable
  4. Custom spool label, outer carton logo, length customization
  5. Professional after-sales technical support for optical cable solution

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.
