Optical data cable GDX702 series

LCSClow-smoke

Product Application
The GDX702 butterfly fiber optic cable comprises two parallel single-mode fibers with reinforcing metal elements and an LS0H outer sheath. It is designed for indoor optical signal distribution at 1310 nm where bend-insensitive performance and low-smoke, zero-halogen behavior are required.

Product Features
Metal strength member ensures fibers remain free of tensile strain after installation. The flat butterfly profile reduces space consumption and maintains fiber geometry. The LS0H outer sheath limits smoke and halogen emissions in fire scenarios and supports code-compliant indoor installations.

Precision-Engineered for Indoor Deployments
The GDX702 is engineered for high-density indoor routing where tight bends and compact pathways are common. The G.657.A1 and G.657.A2 fiber options provide bend-insensitive performance suitable for FTTH drop runs and internal distribution routes while the LS0H jacket reduces toxic emissions.

Reinforced Internal Structure with Metal Strength Member
The central metal strength member absorbs tensile loads during pulling and stabilizes the cable cross-section. The flat butterfly geometry maintains fiber alignment to reduce microbending loss and simplify termination and splicing.

Key Advantages

• Flat butterfly profile with two parallel single-core fibers for space-efficient routing.
• Metal strength member provides mechanical stability and pull resistance for indoor installations.
• LS0H jacket ensures low smoke and zero halogen properties for building compliance.

Typical Use Scenarios

• FTTH deployments in apartment buildings and tight wall conduits (G.657.A2 recommended for the tightest bend radii).
• Structured cabling and office renovations requiring compact routing and easy termination.
• Healthcare and public buildings where low-toxicity materials are required.

Product Advantages — Additional Notes

• Flat butterfly structure minimizes space use and preserves fiber geometry during flexing.
• Metal strength member reduces strain on fibers to improve long-term reliability.
• LS0H outer jacket conforms to flame and smoke performance standards cited above.

FAQ (selected)

• Is this cable compatible with standard SC/APC or LC connectors? — Yes; the butterfly structure supports termination with common connectors including SC/APC and LC.
• Can the G.657.A2 version handle sharp corner bends in tight conduits? — Yes; G.657.A2 supports tighter bend radii and is suitable for sharp routing paths.
• Does the LS0H jacket meet international fire safety standards? — Yes; the sheath complies with the listed national and IEC flame and smoke standards.
