BM-500S Fusion Splicing Machine – Core Alignment Specifications
Alignment & Splicing
Fiber Alignment Method: Core-to-Core digital alignment (active alignment) — aligns fiber cores precisely in two axes for low-loss splicing.

Splicing Time: ~5–6 seconds typical.

Heating Time: ~15–18 seconds (depends on sleeve size; 40mm/60mm).

Typical Splice Loss:

SM (G.652): ~0.01 dB

MM (G.651): ~0.01 dB

DS/NZDS: ~0.02 dB

Return Loss: >60 dB (very high, low reflection).

Splicing Programs: ~40 programmable / stored parameters.

Fiber Compatibility
Applicable Fiber Types:

Single-mode (SMF/ITU-T G.652/G.657)
