Описание (английский):

IEC 62802:2017 specifies measurement methods of a half-wavelength voltage and a chirp parameter applicable to MZMs in microwave and millimeter-wave RoF systems. In addition, these methods are also effective for the estimation of the intermodulation distortions and transmission performances. The methods apply for the following: - frequency range: 5 GHz to 110 GHz; - wavelength band: 0,8 µm to 2,0 µm; - electro-optic material based MZMs and their modules.

Overview

IEC 62802:2017 defines standardized measurement methods for two critical parameters of Mach‑Zehnder optical modulators (MZMs) used in high‑frequency Radio on Fibre (RoF) systems: the half‑wavelength voltage (Vπ/2) and the chirp parameter. The standard targets electro‑optic material‑based MZMs and their modules, covering the 5 GHz to 110 GHz frequency range and optical wavelengths from 0.8 µm to 2.0 µm. These measurement procedures support consistent characterization of modulators for microwave and millimeter‑wave photonic links.

Key Topics and Requirements

Parameters measured

Half‑wavelength voltage (Vπ/2) - drive voltage required to produce a π phase shift in the MZM transfer function.
Chirp parameter - quantifies frequency chirp induced by modulation, affecting RF-to-optical and optical-to-RF conversion.

Measurement scope

Applicable for microwave and millimeter‑wave RoF applications (5–110 GHz).
Optical wavelength band 0.8–2.0 µm.

Measurement methods

Method A: fixed DC‑bias condition (simultaneous Vπ/2 and chirp extraction).
Method B: DC‑bias sweep to derive parameters across operating points.
Method C: measurements using minimum‑transmission and maximum‑transmission bias points.

Test arrangement and conditions

Standard circuit diagrams and transfer‑curve analysis are provided.
Specifies environmental and temperature conditions and warming‑up requirements for measurement equipment.
Guidance on sampling for quality control and appropriate sampling frequency.

Additional considerations

Methods also support estimation of intermodulation distortion and transmission performance of MZMs.
Annex A (informative) covers parallel integrated MZM configurations (quad/dual parallel structures).

Applications and Who Should Use It

Device manufacturers - to characterize and specify MZM drive voltages, chirp, and linearity for product datasheets.

Test and calibration laboratories - for repeatable, standardized Vπ/2 and chirp measurements at microwave/millimeter frequencies.

System integrators and network designers - to assess modulator suitability for high‑frequency RoF links, RF photonics front‑ends, and point‑to‑multipoint wireless distribution.

R&D teams - for material and device comparison when developing electro‑optic modulators for 5G/6G and beyond.
