Carrying bulky heavy fiber test equipment for simple daily FTTH troubleshooting is a burden for front line entry level technicians.
Built for routine FTTx installation and fault repair work, the 1500PRO mini OTDR delivers powerful fiber testing performance in an ultra compact palm size body weighing merely 380 grams. You can easily slip it into your tool pouch or pocket, no more heavy equipment to carry up poles.
Equipped with a 4 inch capacitive touchscreen and beginner friendly one button auto test, even less experienced technicians can complete fiber inspection and get readable test results quickly. It integrates 7 practical functions: OTDR, optical power meter, light source, VFL, event map, RJ45 network cable sequence test and LED flashlight.
Filtered versions support live PON testing with automatic optical protection to prevent module damage. Adopting widely used Type C charging interface, you can power it with common mobile phone chargers for 8 hour continuous field work. It is the cost effective daily work companion for FTTx fault repair, link acceptance and access network maintenance.

FAQ
Q1: What are the differences between 1500PRO, 2100PRO, 2200MAX and 2000PON?
The 1500PRO is palm‑sized mini entry‑level OTDR at only 380g, for daily short‑range FTTx troubleshooting. 2100PRO is mid‑range FTTH model with touch+hard‑key dual‑operation for glove‑friendly field work. 2200MAX is flagship unit for long‑haul backbone testing. 2000PON is dedicated PON OTDR which can test through 1:64 PLC splitter for operator‑grade ODN maintenance.
Q2: What is special about the RJ45 test and LED flashlight function?
Built‑in RJ45 port checks LAN cable sequence and traces cables. Integrated LED flashlight offers auxiliary lighting for dark manholes or cabinet environments.
Q3: Does it use common phone‑type charger for charging?
Yes. It adopts universal Type‑C charging interface, you can use ordinary mobile‑phone chargers for power supply. It provides up to 8‑hour continuous testing and 15‑hour standby time.
Q4: Is this OTDR suitable for new or beginner technicians?
Yes. One‑button auto‑test simplifies operation. New users can obtain test results quickly without professional OTDR‑curve reading experience.
Q5: What trace file format does it support and is PC software available?
It saves traces as standard Telcordia SOR format and supports direct PDF report output. Free PC analysis software is provided for trace review and report processing.
