Frequently Asked Questions
Q: What is the difference between the HSV-630 and HSV-630A?
A: The HSV-630 tests at 1310nm and 1550nm only. The HSV-630A adds 1490nm, 1625nm, and 1650nm wavelengths, enabling live fiber testing at 1625nm without service interruption and network monitoring at 1650nm. Both share the same 37/35dB dynamic range, 0.8m event dead zone, 256K sampling points, and 8GB storage. Choose the HSV-630 for standard 2-wavelength SM testing; choose the HSV-630A when live fiber or multi-wavelength testing is required.
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-630’s 0.8m EDZ enables 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: What built-in test functions does the HSV-630 include?
A: The HSV-630 includes a built-in optical power meter (OPM), 10mW visual fault locator (VFL), and stabilized light source (1310/1550nm) as standard features. An optional 520X USB fiber inspection probe is also available.
Q: How much data can the HSV-630 store?
A: The HSV-630 has 8GB internal memory storing up to 80,000 OTDR traces, plus an 8GB SD card slot for an additional 80,000 traces — 160,000 traces total without any offloading.
Q: What warranty does the HSV-630 come with?
A: The HSV-630 comes with a 1-year manufacturer warranty. For support or bulk pricing, contact us at info@splicermarket.com.
