Thermal Testing & Cycling Solutions for Fiber Optic Products & Components

AGNEW-ASSO proudly represents advanced thermal testing and cycling solutions for fiber optic products and components. With fiber optic transceivers and systems becoming the preferred choice over electrical cables due to their superior data transmission speeds and reliability, rigorous thermal testing is essential to ensure optimal performance and durability. The solutions we represent help manufacturers produce fiber optics and connections with minimal loss performance under both standard and extreme temperature conditions.

Fiber optic transceivers and components are critical in internet applications, satellite communications, and aerospace systems, where reliability is required even at temperatures ranging from -55˚C to 125˚C to meet military specifications (883C). The thermal testing units we represent are designed to evaluate this reliability, ensuring these components excel in the demanding environments they are designed to support.

AGNEW-ASSO connects manufacturers with high-precision thermal testing solutions capable of testing at even stricter ranges, from -100˚C to 300˚C, with an accuracy of +/- 1 degree. These solutions provide electronic noise-free and moisture-free environments to enable accurate analysis of component failures, functionality, and product life cycles. The systems we represent, including advanced thermal enclosures, offer the ideal solution for meeting the high-level demands of the fiber optics industry and ensuring exceptional product performance.

ThermalAir TA-Series of Temperature Forcing Systems

ThermalAir temperature cycling solutions play a critical role in the thermal testing of fiber optic devices during both development and production stages. These systems are engineered to support processes such as thermal tuning, calibration, and environmental conditioning within a controlled range of -40°C to +90°C—ensuring that each component performs reliably under varying temperature conditions.

The TA-Series lineup—including the TA-5000 (-80°C to +225°C), TA-3000 (-65°C to +225°C), and TA-1000 (-25°C to +200°C)—delivers precise hot and cold air directly onto fiber optic assemblies. With temperature accuracy up to ±1.0°C, these systems enable consistent, localized thermal application for a wide variety of fiber optic components, enhancing reliability, throughput, and test efficiency.

MPI Thermal’s Temperature Inducing Systems

MPI Thermal’s temperature inducing systems are designed with portability in mind, allowing engineers to conveniently transport the equipment between test stations. For fiber optic component manufacturers, the ThermalAir TA-3000 system enables direct, on-site temperature conditioning—bringing the test environment to the device rather than relocating sensitive parts to fixed chambers.

These systems support a range of critical test methods including temperature cycling, thermal profiling, and environmental stress screening. This makes MPI Thermal solutions an integral part of the temperature validation process in manufacturing workflows.

For consistent, accurate, and flexible temperature testing, the TA-3000 Series from MPI Thermal continues to be the go-to solution for ensuring product reliability under varied thermal stress conditions.

ThermalAir Systems for SFP Fiber Optic Transceiver

The small form-factor pluggable (SFP) is a compact, hot-swappable transceiver module widely used in telecommunications and data communications for high-speed network connectivity. SFP modules support a range of standards, including SONET, Gigabit Ethernet, Fibre Channel, Passive Optical Networks (PON), and more.

MPI Thermal’s ThermalAir systems are engineered to meet the thermal testing requirements for advanced optical transceivers operating at speeds of 25G, 40G, 100G, 400G, 800G, and up to 1.6T. These systems deliver a consistent and controllable thermal environment—typically between -40°C and +90°C—to support standardized temperature cycling for high-speed fiber optic components.

The TA-5000 temperature forcing system from MPI Thermal offers precise hot and cold air delivery for evaluating the performance and thermal behavior of microelectronic, optoelectronic, and related components. Whether conducting basic thermal profiling or evaluating critical performance parameters over temperature, these systems ensure optical transceivers and laser devices are validated for use in a range of industrial, commercial, and consumer applications.

ELI-1000 Thermal Chamber | Temperature Chamber

The ELI-1000 Thermal Chamber, a revolutionary temperature control system that combines a closed-loop thermal source and interchangeable custom/standard testing chamber into one compact, energy efficient system with a standard 110 volt electric source, has surpassed long-term sales expectations set when it was released over a decade ago.

The Khoury Box | RF, Microwave Thermal Testing

Electronics are a big part of technological advances found in everything today – including many of the parts found in automobiles, video game systems, medical equipment, airplanes, and even military weapons. These parts are subjected to extreme temperature fluctuations and transitions during use. Khoury Industries proudly manufactures the industry-leading Khoury Box, a temperature chamber or thermal chamber that holds the device-under-test so that thermal testing can be done to ensure reliability and durability of a product.

Specifically, the device-under-test is placed into the temperature chamber or thermal chamber and subjected to rigid thermal cycling in which the air is raised and lowered between temperatures that may match or exceed expected service environments to simulate different conditions. The Khoury Box temperature chamber operates in temperatures ranging from -80˚C to +225˚C.
