CuBLU: AEM Networks’ New Copper Cabling Verification Test Set
AEM Networks recently introduced CuBLU, which the company describes as “a new range of copper cable testers designed to bring professional testing features, clearer diagnostics, and app-based documentation to everyday field-testing and troubleshooting work.”
The tester series includes 3 models: CuBLU is the basic model for what AEM calls “straightforward copper testing,” while CuBLU II adds Bluetooth app connectivity and reporting and CuBLU III adds Power over Ethernet detection.
“Across the range, the testers are built to support everyday copper cable work in structured cabling installations, data centers, construction and fit-out projects, smart buildings, security and AV environments, enterprise IT and facilities teams, as well as electrical and low-voltage contractors,” the company pointed out when introducing the CuBLU series.
“Developed for installers, technicians, and field teams who need more than a basic wiremap tester, CuBLU delivers practical field intelligence,” AEM Networks continued. “The series is designed to help users identify cable runs, identify wiring faults, trace cables, detect DC voltage, work with multiple remote IDs, and document results through the UniBLU app on selected models.”
All models include a rechargeable lithium-ion battery with USB-C charging and a 45-hour battery life along with a color TFT LCD [thin film transistor liquid crystal display], up to 16 remote IDs, tone generation, and DC voltage detection up to 60V before every test, protecting both the technician and the tester,” AEM added.
CuBLU II and CuBLU III also add cable-length measurement up to 120 meters and DC resistance per pair, which is an increasingly important parameter for PoE applications.
CuBLU III’s PoE detection enables technicians to identify PoE class, voltage and powered pairs, up to IEEE 802.3bt-specified 90 watts, allowing techs to identify powered Ethernet ports.
“CuBLU was created to raise the standard for everyday copper testing,” said Harshang Pandya, AEM Networks’ general manager. “Installers in this segment are often offered basic tools that only confirm continuity. CuBLU brings them a more capable and professional testing experience, with clearer fault insight, stronger field productivity, and practical features that are not typically available in many comparably priced testers.”
CuBLU identifies open, short, miswire, crossover, split pair, and multifault fault types, along with shield detection, across the entire series. “This gives technicians clearer answers than a basic failure indication and helps reduce troubleshooting time during installation, verification, and maintenance work,” AEM pointed out.
AEM specifically pointed out the app-based documentation and reporting, through the UniBLU app, that CuBLU II and CuBLU III offer. “With Bluetooth connectivity, technicians can save, view, and export test results, complete with cable labels, directly from the field, helping teams create a clearer record of completed work without relying on manual notes, screen photos, or end-of-day paperwork,” the company said. “UniBLU is the same app used with the FiBLU fiber certifier, so one crew can work with a single app across copper and fiber.”
Pandya added, “In today’s projects, testing is not just about finding faults. It is also about proving that the work was completed properly. App-based documentation gives installers a cleaner, more-professional way to record results, support handover, and provide customers with greater confidence in the quality of the installation.”
