Product Description
G657A1 G657A2 Bend Insensitive Single Mode Fiber Optic Patch Cord SC LC FC ST for FTTH Data Center
G657A1 / G657A2 Bend Insensitive Single Mode Fiber Optic Patch Cord
ITU-T G.657 Compliant | 7.5mm Minimum Bend Radius | Macro-Bend Optimized | SC LC FC ST Connectors
- 7.5mm Minimum Bend Radius: G657A2 supports bends as tight as 7.5mm radius without significant signal degradation — ideal for MDU in-building wiring, tight corners, and high-density patching fields.
- G652D Backward Compatible: G657A1/A2 fibers are fully compatible with standard G652D fiber — seamless splicing and connectorization with existing network infrastructure. Mode field diameter matched at 1310nm.
- FTTH MDU Optimized: Specifically engineered for multi-dwelling unit in-building FTTH deployments where cables must navigate tight corners, small conduits, and crowded cable trays without performance loss.
G657A1 vs G657A2 vs G652D — Bend Performance Comparison
| Parameter | G652D (Standard) | G657A1 (BIF) | G657A2 (Advanced BIF) |
|---|---|---|---|
| Min Bend Radius | 30mm | 10mm | 7.5mm |
| Bend Loss (1 turn, 7.5mm R) | ≥5.0dB | ≤2.5dB | ≤0.5dB |
| Bend Loss (1 turn, 10mm R) | ≥3.0dB | ≤0.75dB | ≤0.1dB |

| Best Application | Long-haul / Metro | FTTH Drop / Last Mile | MDU / Data Center / Tight Routing |
Applications
FTTH In-Building MDU
Multi-floor risers with tight 90-degree turns in small conduits. G657A2 handles bends that standard G652D cannot.
High-Density Data Center
Tight cable management in 1U and 2U patch panels. Reduced bend loss ensures consistent link budgets in crowded racks.
Fiber to the Room (FTTR)
Invisible fiber deployment along baseboards, door frames, and through wall corners without performance penalty.
