Multi-touch Touchscreen
5.0 inch multi-touch capacitive touchscreen can make OTDR operations simple and intuitive. The
technicians can easily tap, pinch and drag by fingers with quick OTDR response

OTDR View Modes

MTP-50 series OTDR can generate and display events by traditional TRACE view and MAP view.
Traditional TRACE view is showed by OTDR waveforms and event markers while MAP view is with
simple, icon-based map for easy interpretation of fiber network events.

TRACE View MAP View

Auto OTDR
Simply pressing one single button, powering by fully automated and optimized test parameter setup,
MTP-50 series OTDR can process OTDR measurement, detects and comprehensively analyze
network events with PASS/FAIL judgement based on user-defined thresholds. It greatly helps OTDR
beginners operate OTDR more efficiently.

Expert OTDR
OTDR test parameters can be set manually depending on test requirements or the technicians skill
level. The fiber trace is displayed and results are listed in event table including total fiber length,
total link loss, fiber attenuation, etc.

Link Image
Link Image software helps technicians use an OTDR more efficiently, without the need to
understand or interpret OTDR results. Measurement acquisitions with multi pulse widths and smart
algorithm enable the technicians to detect and comprehensively characterize network events by
pressing one single button. Simple icon-based map view for easy interpretation of network events
with PASS/FAIL judgement as per user-defined thresholds.

• Icon-based fiber link view of all events

• Automatic pass/fail results
• Eliminates the need for OTDR expertise

Visual Fault Locator

Outputs red light for checking continuity of launch fibers
or short patch cord. Breaks and bending in fiber can be
identified visually.

Optical Power Meter
• No warm-up
• High accuracy, zero shift
• Reference setting
• Absolute power value and
power loss measurement

Stabilized Laser Source

Stabilized Laser Source shares OTDR optical port and
work on the same working wavelength of OTDR. The
output power can be adjustable for different testing
applications. With modulated light at
270Hz/330Hz/1kHz/2kHz, it can be used for fiber
identification or continuity check purpose on a live fiber
network.

Optical Loss Test

Optical loss test is a key basic function for confirming
the optic fiber installation condition and fault status.
Light source shares with OTDR ports outputs laser light.
The optical power meter function is embedded into a
separate port which supports optical loss measurement
by one single tester.

USB Power Charging and Data Transfer
USB port can be used for power charging and data transfer which is very convenient for technicians
operation in the filed. No need to carry a bulky AC adaptor anymore and even can be charged by
portable power bank.

Multi-tasking
Leveraged by excellent hardware design, the technicians can perform multiple functions
simultaneously. For example, the technicians can conduct OTDR testing on a particular fiber while
checking the power level by OPM function or identifying the fiber with VFL function simultaneously
on other fiber cores.

Multi-language User Interface

Supported with Mutli-language user interface, the technicians can operate MTP-50 series OTDR
with their native language easily and smoothly.

Simple Firmware Upgrades

Firmware upgrades can be performed easily via USB Type C port which connecting with PC.

OTDR PC Software
OTDR PC software can display, analyze and edit trace files, generate and print comprehensive test
and analysis reports.

• Trace viewing, events analysis

• Flexible batch printing
