What we build

Three product lines carry most of what our customers ask for: fusion splicers, visual fault locators and optical power meters. Every model below is specified in full on its own page.

Fiber Optic Fusion Splicers

GUANGYAN fusion splicers use six-motor active core alignment to align the fibre cores themselves, not just the cladding, which is what keeps splice loss low and repeatable across a working day. Splice cycles run 6 to 8 seconds depending on model, with an optical power meter and visual fault locator built into the same body so a technician carries one instrument instead of three.

  • ✓Six-motor core alignment on every model
  • ✓6s (M6 / K6) or 8s (K5 / M5 / K3S) splice cycle
  • ✓Integrated OPM + VFL, no separate meters to carry
  • ✓4.3" or 5" touch screen, 5200–7800mAh battery

Visual Fault Locators (VFL) manufactured by GUANGYAN, 8 models

Visual Fault Locators (VFL)

A visual fault locator injects a bright laser into the fibre so breaks, tight bends and bad connectors show up as a glowing point you can find by eye. GUANGYAN builds eight VFL models from pen-sized 5mW units up to 50mW all-metal bodies, including 510nm green-light versions for fibres where red is hard to see.

  • ✓650nm red light, 5 / 15 / 20 / 30 / 40 / 50mW options
  • ✓510nm green light on B3G and B5G for higher visibility
  • ✓2.5mm universal adapter fits SC, ST and FC
  • ✓Constant and flashing modes, all-metal housings

Optical Power Meters

Optical power meters measure how much light actually arrives at the far end of a link, which is the number that decides whether a span passes or fails. GUANGYAN offers eight models covering 850 to 1625nm at ±5% accuracy, from pocket pen-style units to handheld meters with colour displays and stored test records.

  • ✓850–1625nm wavelength coverage, ±5% accuracy
  • ✓Auto frequency recognition (270 / 1000 / 2000Hz)
  • ✓Self-calibration and stored test records
  • ✓AA battery or rechargeable lithium, up to 48h runtime
