Telebyte is the leader in channel emulation for broadband data communication systems, with a reputation built on 30+ years of innovation, customer service and product quality.

Headquartered in New York State, USA, Telebyte’s solutions are used by companies around the world for a variety of physical layer testing applications such as IoT, Telco rate/reach, qualification, R&D, interoperability, vendor trials and more.

Telebyte recognizes the many challenges with single pair ethernet such as communicating over great distances, operating in harsh industrial environments, and providing Power over Data Line (PoDL) on a single pair. Our test and measurement equipment will play an essential role in meeting those challenges.

Our years of experience with channel emulation, noise generation and test automation have shown us that standardization in testing methods and independent test gear are of great importance for any technology to succeed. This develops the trust and reliability needed to accelerate SPE technology. Telebyte’s equipment will follow the industry standards allowing us to be an independent test and measurement equipment provider.

Telebyte also understands that reliability, quality and superior product support are of immense value to our customers. We will be a trusted partner, helping our customers meet their SPE technology goals.

“Your Trusted Partner in SPE Testing.”

Primary Focus of New Product Development: SPE testing solutions for Compliance, Safety and Interoperability applications.

SPE Product Line

Our testing solutions utilize Telebye SPE products and offer multi-purpose configurations for use during product development, conformance and interoperability testing of power and data, as well as simulation of a real-world field environment in the laboratory.

Single Pair Ethernet (SPE) Cable Emulator: Emulates the physical layer twisted pair copper cable properties defined in the IEEE 802.3cg-2019 standard for 10BASE-T1L for both 1.0Vpp and 1.4Vpp operation modes. This product supports Power over Data Line (PoDL) for Class 10 -15 Devices safety testing and allows you to vary the DC Loop Resistance to test that the Power Source Equipment (PSE) will deliver sufficient power to the Powered Device (Pd) for a stable SPE link. The cable emulator may also be used to introduce cable faults such as a faulty wire connection at a terminal block that may cause impedance mismatches that results in data errors. Also included, a differential noise injector on each end of the cable to mix noise with the 10 Mbps Ethernet signal that may be coupled into the twisted pair cable in different environments to do system level testing.

SPE Multifunction Probe: Test instrument is designed specifically for testing Single Pair Ethernet (SPE) 10BASE-T1L with Power over Dataline (PoDL) as defined in the Ethernet-APL Data Test Specification v1.5, Power Test Specification v1.2 and the IEEE 802.3-2022 standard.

This specialized instrument is used with the Telebyte’s Channel Emulator to test a wide range of Power Source Ports (PSE) and Powered Device (PD or Load) ports in applications such as Auto-Negotiation Tests,  Transmitter Tests, BER Receiver Test, Power coupling and decoupling, noise generation (including background and impulsive noise), noise capture to replicate field environments in the lab, Power Spectral Density (PSD) and power level measurements, Transmitter clock frequency, distortion and jitter measurements, Voltage Droop, MDI Return Loss, PoDL / SPoE measurements and more.  

SPE Test Automation Software: Software provides easy control and configuration of the devices in the test bed as well as data storage and reporting. This automates, unifies, standardizes and simplifies the testing process, thereby enabling repeatability across implementations, saving time and lowering costs.

Standardization in testing methods is of great importance for any technology to succeed. This develops the trust and reliability needed to accelerate SPE technology. Our convenient and efficient software is designed for automated testing of various SPE standards, including Ethernet-APL, and 10BASE-T1L / SPoE. 

Universal Noise Generation Software: Testing with realistic noise environments is important to verify the physical layer performance of 10-BASE-T1L devices. Reporting the correct Mean Squared Error (MSE) value and calculating the corresponding SNR is a key indicator for low or error-free data traffic performance.

The Universal Noise Generation software supports Arbitrary Waveform Generators (AWGs) and noise from 20 kHz to 200 MHz on two independent noise ports. The AWG is used with the Telebyte Differential Noise Injector to inject noise with a high impedance and a crest factor greater than 5. Allows injection of differential noise on each device on the link segment or one device with combined noise (time + frequency domain) from two channels.

Alien Crosstalk or Impulse Noise may be used for system or pre-deployment testing in the lab.

Switching Matrixes: Model 600 Switching Matrix Series allows users to switch multiple groups of 10BASE-T1L Single Pair Ethernet (SPE) source-to-load devices such as Ethernet APL Power Switches and APL Ethernet Powered Devices into the test environment. Supports Power over DataLine (PoDL) Classes 10-15 for 10BASE-T1L, Single Pair Ethernet (SPE) test beds with trunk-to-spur, trunk-to-trunk, or spur-to-spur testing. Save time with automated testing of twisted pair, 2-wire Single Pair Ethernet for simple field connection, 10Mbps Data Rate with full duplex communication with test trunk lengths up to 1100m, and spurs up to 150m.

Spur Emulator: Emulates eight channels of two-wire spur cable segments (of under 200m) between a 10Base-T1L field Power Switch and field Powered Devices (PD) that draw power from the switch to operate and communicate. The passive design features a very low noise floor – providing realistic, repeatable Single Pair Ethernet (SPE) test results for field switches and powered devices.
