Anritsu Company has launched the MN4765B-0140 O/E Reference Calibration Module, the world’s fastest and first traceable solution to support the testing demands of next-generation data centres and the explosive growth of artificial intelligence (AI) and machine learning.
As data centres transition from 224 to 448Gbps per lane to achieve total data rates like 1.6T, the required bandwidth for electrical-optical (E/O) modulators and optical-to-electrical (O/E) photodetectors now exceeds 130 GHz. The new MN4765B-0140 is engineered to meet this critical need, pushing the measurement frontier to 145GHz.
Key technological breakthroughs
The MN4765B-0140 is a monumental step forward for high-speed component verification:
- World’s first 145GHz reference photodetector: It offers the widest commercially available frequency range from 70kHz to 145GHz for O/E calibration at the 1550nm wavelength, enabling the high-confidence characterisation of cutting-edge E/O and O/E devices.
- Traceability to 145GHz: Anritsu secured traceability for the new module to a recognised National Metrology Institute. This is a crucial differentiator, as existing standards from NIST are limited to 110GHz, making the MN4765B-0140 the only solution providing verifiable measurement accuracy at these extreme bandwidths.
- Unique, cost-effective system solution: When integrated with Anritsu’s VectorStar ME7838D 145 GHz Vector Network Analyzer (VNA), the combination creates the world’s only complete, traceable, and flexible system for testing the entire high-speed opto-electronic ecosystem, including TOSA, ROSA, BOSA, and Coherent Optical Sub-Assemblies (COSA).
Securing investment in high-speed R&D
Anritsu’s solution provides significant advantages over competing systems, which typically forces customers into a more expensive solution lacking the necessary 145GHz reference calibration module entirely.
“The AI revolution is demanding a massive leap in data centre interconnect speeds, making the 145GHz bandwidth non-negotiable for 1.6T deployment,” said a spokesperson for Anritsu Company. “The MN4765B-0140 eliminates measurement uncertainty at these critical frequencies. Coupled with the flexible and future-proof VectorStar VNA platform, our customers gain a powerful, cost-effective tool that secures their investment by offering a simple upgrade path and superior measurement speed.”
