HSV-630A OTDR | 5-Wavelength 1310/1490/1550/1625/1650nm, 37dB, 0.8m Dead Zone, Live Fiber Test

HSV-630A OTDR – 5-Wavelength Professional OTDR with 1625nm Live Fiber Testing

The HSV-630A is a high-performance handheld OTDR engineered for demanding telecom, FTTx, and metro network testing. Its defining advantage over standard 2-wavelength OTDRs is a full 5-wavelength capability (1310/1490/1550/1625/1650nm) — including 1625nm for live fiber testing without interrupting active services, and 1650nm for specialized network monitoring. Combined with a 37/35/35dB dynamic range, an industry-leading 0.8m event dead zone, and a 400km distance range, the HSV-630A is built for engineers who need the most complete fiber characterization in a single tablet-inspired handheld instrument.

Why Choose the HSV-630A?

• 5-Wavelength Testing (1310/1490/1550/1625/1650nm): The most comprehensive wavelength coverage in its class — including 1625nm for live fiber testing and 1650nm for network monitoring, without service interruption
• 37/35/35dB Dynamic Range: High dynamic range for testing long-haul backbone fiber, high-loss PON networks, and complex multi-span links up to 400km
• 0.8m Event Dead Zone: One of the shortest event dead zones available — detects closely spaced connectors, splices, and events in dense central office and data center environments
• 5cm Minimum Distance Resolution: Ultra-precise 0.05m sampling resolution for accurate event location on short fiber spans and dense patch panels
• 256,000 Sampling Points: Maximum trace detail for comprehensive fiber characterization across the full 400km distance range
• 8GB Internal Storage (80,000 Traces): Massive onboard storage plus 8GB SD card slot for unlimited field data collection without offloading
• 7-Inch Outdoor-Enhanced Touchscreen: 800×480 TFT display optimized for bright outdoor conditions — the largest display in the handheld OTDR class
• Built-in Power Meter, VFL & Light Source: Integrated OPM (850–1610nm, ±0.17dB), 10mW VFL (650nm), and stabilized light source (1310/1490/1550/1625/1650nm, -4dBm) eliminate the need for separate instruments
• 520X Fiber Inspection Probe (USB): Optional fiber inspection probe for connector end-face inspection directly from the OTDR
• 12-Hour Battery Life: 5300mAh lithium battery pack for a full day of field testing
• Multi-Language Support: Chinese, English, Spanish, Russian, Italian, Portuguese, and more
• 1-Year Warranty

Frequently Asked Questions

Q: What is the advantage of 1625nm testing on the HSV-630A?
A: The 1625nm wavelength allows testing on live, in-service fiber without interrupting active data traffic. The HSV-630A’s built-in 1625nm live port filter (highpass >1595nm) isolates the test signal from live traffic, enabling maintenance and troubleshooting on active networks — a critical capability for telecom operators who cannot take services offline.

Q: What does the 0.8m event dead zone mean in practice?
A: The event dead zone is the minimum distance after a reflective event before the OTDR can detect another event. The HSV-630A’s 0.8m EDZ is among the shortest available in handheld OTDRs, enabling detection of events as close as 0.8m apart — essential for testing dense patch panels, splice trays, and short fiber runs in central offices and data centers.

Q: How does the HSV-630A compare to the HSV-630?
A: The HSV-630 tests at 1310/1550nm only. The HSV-630A adds 1490nm, 1625nm, and 1650nm wavelengths, enabling live fiber testing at 1625nm and network monitoring at 1650nm. Both share the same 37/35dB dynamic range and 0.8m event dead zone. Choose the HSV-630A when multi-wavelength or live fiber testing is required.

Q: What optional accessories are available for the HSV-630A?
A: The HSV-630A supports an optional 520X USB fiber inspection probe for connector end-face inspection. The built-in OPM, VFL, and light source are standard features, not optional add-ons.

Q: What warranty does the HSV-630A come with?
A: The HSV-630A comes with a 1-year manufacturer warranty. For support or bulk pricing, contact us at info@splicermarket.com.
