💡 Best Value Professional OTDR
The MAX-600-M1 delivers the same 7-inch touchscreen platform and professional UI as the higher-spec MAX-600-M3, at a more accessible price point — making it the smart choice for technicians who need reliable OTDR performance for standard FTTH and access network applications.
✅ FAQ
Q1: What is the dynamic range of the COMWAY MAX-600-M1 and what distance can it test?
A: The MAX-600-M1 offers 32dB at 1310nm and 30dB at 1550nm, enabling fiber testing
over distances of approximately 60–80km depending on fiber quality — ideal for FTTH
access networks and short metro links.
Q2: What is the difference between the MAX-600-M1 and MAX-600-M3?
A: The MAX-600-M3 offers higher dynamic range (39/38dB vs 32/30dB) and adds a live
1625nm wavelength for PON testing. The MAX-600-M1 is the best-value choice for
standard FTTH and access network testing where 1625nm is not required.
Q3: Does the MAX-600-M1 include a power meter and VFL?
A: Yes. The MAX-600-M1 includes built-in VFL (Visual Fault Locator), optical power
meter (OPM), and light source — plus an optional fiber inspection probe module.
Q4: What connector types are available?
A: Available in SC/APC, FC/APC, SC/UPC, and FC/UPC. Select your preferred connector
type at checkout.
Q5: How long does the battery last on the MAX-600-M1?
A: The 4,600mAh Li-ion battery provides 12 hours of continuous operation — sufficient
for a full day of field testing.
Q6: Is the MAX-600-M1 suitable for outdoor field use?
A: Yes. The MAX-600-M1 operates from -10°C to +50°C and is housed in a rugged,
lightweight 1.0kg enclosure designed for field use.
