Application Background

In the field of high-speed optical communication, 400G/800G/1.6T modules are core components of next-generation data centers and backbone networks, with extremely high requirements for reliability and bit error rate (BER). During the R&D, mass production testing, and verification stages of optical modules, BERT tests need to be performed on them at different ambient temperatures to evaluate the performance stability of the modules in high-temperature, normal-temperature, and low-temperature environments.

Blue Guardian TEC Temperature Control Solution Introduction

BlueGuard's TEC temperature control solution, with its advantages of high precision, fast response, bidirectional temperature control, and rapid customization, provides reliable high and low temperature environment simulation for optical module bit error rate testing. It significantly improves the accuracy and efficiency of optical module bit error rate testing, making it an ideal solution for temperature control systems in high-end optical communication test instruments.

Solution advantages

The intelligent PID algorithm combines self-tuning, adaptive and predictive compensation mechanisms to dynamically adjust control parameters according to different controlled objects and environments, achieving faster response speed, higher steady-state accuracy and better anti-disturbance performance, with temperature control accuracy up to ±0.1℃.

Multi-channel independent temperature control: Supports independent temperature control for multiple channels, each with independent data acquisition and execution capabilities, ensuring no interference. Different target temperatures can be set for each channel, enabling simultaneous testing or differentiated verification of multiple modules. This significantly improves equipment utilization and testing flexibility, making it particularly suitable for multi-port parallel batch testing platforms for optical modules.

Available in 2/4/8 channels to meet diverse application scenarios, the BlueGuard TEC temperature controller series offers various specifications including 1, 2, 4, and 8 channels. It supports multiple communication methods such as TCP, RS485, and RS232, allowing for flexible integration into different control systems. The rich model configurations meet diverse needs, from single-point temperature control to multi-channel synchronous control.

Application value of the solution

01. Enhanced Testing Accuracy and Consistency

Utilizing the high-precision bidirectional temperature control technology of the BlueGuard TEC temperature controller, temperature stability is achieved better than ±0.1℃, effectively eliminating interference from ambient temperature fluctuations in bit error rate testing. Independent temperature control for each channel ensures the repeatability and consistency of test results for optical modules under different thermal environments, providing reliable temperature control assurance for high-speed optical module performance verification.

02. Improved Testing Efficiency and Automation

Supports multi-segment temperature control, allowing rapid switching between low, normal, and high temperature conditions. Fast heating and cooling speeds and short response times significantly shorten the testing cycle. Linkage with a host computer system via a communication interface automates the testing process, improving the overall testing efficiency of the production line.

03. High Integration and Operational Reliability

Integrates temperature acquisition, drive, and temperature control into one unit, simplifying wiring and system setup. Built-in multiple protection mechanisms, including over-temperature, over-current, open-circuit, and short-circuit protection, ensure stable and reliable operation during long-term continuous operation.
