✅ FAQ
Q1: What wavelengths does the COMWAY MAX-600-M3 support?
A: The MAX-600-M3 supports 1310nm, 1550nm, and live 1625nm wavelengths, allowing you
to test active PON networks at 1625nm without disrupting live traffic on 1490/1550nm.
Q2: What is the dynamic range of the MAX-600-M3 and what distance can it test?
A: With a dynamic range of 39/38dB at 1310/1550nm, the MAX-600-M3 can test fiber spans
of up to 130km+ depending on fiber quality and splice loss, covering both access and
long-haul network segments.
Q3: What is an event dead zone and why does 0.8m matter?
A: The event dead zone is the minimum distance after a reflective event (like a connector)
where the OTDR can detect another event. At 0.8m, the MAX-600-M3 can identify closely
spaced splices and connectors that lower-spec OTDRs would miss.
Q4: Can the MAX-600-M3 test live PON networks?
A: Yes. The 1625nm live fiber testing wavelength allows you to perform OTDR measurements
on active GPON/EPON networks without interrupting customer services.
Q5: What connector types are available for the MAX-600-M3?
A: Available in SC/APC, FC/APC, SC/UPC, and FC/UPC — select your preferred connector
type at checkout.
Q6: Does the MAX-600-M3 include a power meter and VFL?
A: Yes. The MAX-600-M3 includes built-in VFL (Visual Fault Locator), optical power meter
(OPM), and light source. An optional fiber inspection probe is also available.
