COMWAY MAX-600-M4 Quad OTDR | SM+MM 850/1300/1310/1550nm, 4-Wavelength, 7" Touch

COMWAY MAX-600-M4 — The Ultimate 4-Wavelength SM/MM QUAD OTDR

The COMWAY MAX-600-M4 is a unique 4-wavelength SM/MM QUAD OTDR that combines single-mode (1310/1550nm) and multimode (850/1300nm) testing in a single handheld device. Whether you're commissioning a modern SM FTTH network or testing legacy MM fiber in enterprise or campus environments, the MAX-600-M4 eliminates the need for two separate OTDRs — saving cost, weight, and complexity in the field.

✅ FAQ

Q1: What makes the COMWAY MAX-600-M4 a "QUAD OTDR"?
A: The MAX-600-M4 tests at four wavelengths — 850nm and 1300nm for multimode (MM) 
fiber, and 1310nm and 1550nm for single-mode (SM) fiber — making it a complete 
SM/MM OTDR solution in a single handheld device.

Q2: Who needs a SM/MM QUAD OTDR like the MAX-600-M4?
A: The MAX-600-M4 is ideal for contractors and network engineers who work on both 
modern SM FTTH networks and legacy MM fiber in enterprise, campus, or data center 
environments — eliminating the need to carry two separate OTDRs.

Q3: What is the dynamic range of the MAX-600-M4 for SM and MM fiber?
A: For SM fiber: 36dB at 1310nm and 34dB at 1550nm. For MM fiber: 26dB at both 
850nm and 1300nm — covering typical enterprise and campus MM fiber distances.

Q4: Does the MAX-600-M4 include VFL and power meter functions?
A: Yes. The MAX-600-M4 includes built-in VFL, optical power meter (OPM), and light 
source, plus an optional fiber inspection probe module.

Q5: How does the MAX-600-M4 compare to the MAX-600-M1 and M3?
A: The M1 is SM-only (1310/1550nm, 32/30dB). The M3 adds live 1625nm for PON testing. 
The M4 is the only model that adds MM testing (850/1300nm), making it the most 
versatile option for mixed-fiber environments.

Q6: What connector options are available for the MAX-600-M4?
A: Please contact us for available connector options for the MAX-600-M4.
