Complete List of Specifications and Models for Fusion Spliced ​​Optical Cables

Fusion spliced optical cables utilize splice-on connectors and fusion splicers designed for high-performance, low-loss fiber connections, with models supporting single-mode, multi-mode, and specialized fibers.

Fusion Splice-On Connectors

LC and SC splice-on connectors are widely used for field terminations and repairs. Key specifications include:

• Standards Compliance: TIA/EIA-604 FOCIS-3 (SC) and FOCIS-10 (LC)
• Fiber Compatibility: Single-mode and multi-mode fibers, 250µm and 900µm cable diameters
• Performance: Exceeds TIA/EIA-568-D.3 for insertion loss (IL) and return loss (RL)
• Temperature Range: -40°C to 75°C
• Features: Pre-polished ferrule assembly, no field polishing or adhesives required, angled physical contact polish available
• Installation Time: Termination in under two minutes per connector
• Applications: Enterprise, data center, MAC work, and repair of existing links
• Compatibility: Works with Sumitomo brand splice units and typical fusion splice machines for real-time splice loss calculation

Fusion Splicers

Fusion splicers are categorized by alignment type and application: 1. Core Alignment Fusion Splicers

• High precision for single-mode fibers
• Automatic fusion control and real-time splice loss calculation
• Suitable for R&D, factory, and telecommunication applications 2. Cladding Alignment Fusion Splicers
• Portable and ruggedized
• Ideal for field deployment and FTTH installations 3. Mass Fusion Splicers
• 16-core splicer: Data center construction
• 4-core splicer: FTTH cable installation
• Supports specialized fibers: PANDA polarization-maintaining, thin-diameter, large-diameter, and multi-core fibers
• Bluetooth-enabled for stable communication with tools and accessories Example Models:
• AFL S018319 Fujikura 45S: Cladding alignment, 6-second splicing in SM FAST mode, 15–22 second heat time for 60mm sleeves, 20,000 results storage, 5" touchscreen, shock/dust/moisture resistant, includes fiber cleaver, strippers, holders, electrodes, and carry case
• Fujikura Core Alignment Splicers: Automatic fiber clamping, multiple splice and heat modes, suitable for single-mode and multi-mode fibers

Splicing Standards and Procedures

• ITU-T L.400/L.12 specifies splicing procedures for single-mode and multi-mode fibers, including single fibers and ribbons
• Performance Metrics: Low splice loss, tensile strength near fiber proof test level, stability over design life
• Splice Types: Fusion and mechanical splices, with fusion preferred for permanent, low-loss connections
• Alignment Methods: Active core, active cladding, and passive V-groove alignment
• Validation: Average and maximum attenuation measured for 97% of splices

Fiber Preparation and Accessories

• Stripping Tools: Multi-hole strippers for 250µm and 900µm fibers
• Cleaving: Precision fiber cleavers for single and multi-fiber applications
• Cleaning: Critical to remove dust, oil, or debris to ensure low-loss splices
• Safety: Use high-rated goggles, cut-resistant gloves, and anti-static measures due to high-temperature fusion arcs and glass shards

Summary

Fusion spliced optical cables rely on a combination of splice-on connectors, fusion splicers, and proper fiber preparation tools. Models vary by alignment type, fiber compatibility, and application, with standards compliance ensuring reliable, low-loss connections. Popular models include Fujikura 45S, Fujikura core and cladding alignment splicers, and LC/SC splice-on connectors for rapid field deployment. Following ITU-T L.400/L.12 procedures and proper fiber handling ensures high-quality, durable splices suitable for enterprise, data center, and FTTH networks.
