T5500A Network Tester
A high-performance, handheld tester that integrates 10 Gigabit Ethernet, IPRAN/OTN, E1/V.35 interfaces, an optical power meter, and an infrared light source.
Highlights

- One device covers Ethernet, E1, V.35, optical power, and infrared light source testing, reducing the number of devices carried out in the field
- Supports 10G optical ports, Gigabit optical/electrical ports, E1 (75Ω/120Ω), and V.35/V.24, meeting needs for a smooth transition from traditional TDM to modern IP networks
- Supports IP/VLAN automatic discovery, port positioning, loop detection, ARP scanning, TCP delay testing, and rapid location of network fault points
- It has a large screen, a 12000 mAh battery that supports 6 hours of continuous work, and supports in-vehicle charging, making it suitable for outdoor mobile operations.
- Full protocol coverage: supports RFC2544, DHCP detection, frame relay, PPP/HDLC, MPLS, etc., with carrier-grade testing capabilities.

Real Experiences with Network Testers
Michael T.
“It is an absolute game changer. Having Ethernet, E1, PRI and power meter tests all in one device saves so much time and gear. It’s easy to operate, and has greatly simplified our network maintenance workflow.”
Scott N.
“The tester stands out for its versatility. We no longer need to carry multiple testers — this one unit does it all, from optical measurements to data interface checks. The performance is stable, and the results are precise. A perfect tool for telecom professionals.”
