Free Space Optics (FSO) is a communication system that uses light propagation in free space through air or free space as a transmission medium to transmit data.
With the increasing use of free space optics, the Indonesian government, through Decree of the Minister (KEPMEN) No. 43 Tahun 2025 from the Ministry of Communication and Digital (KOMDIGI) has established Free Space Optics testing standards to ensure that these devices are safe, efficient, and do not interfere with each other.
This regulation is intended to ensure that all free space optics devices circulating in Indonesia must ensure their quality, safety, and compliance with applicable regulations through testing standards.

Free Space Optics Testing Standard
Before being used or marketed in Indonesia, free space optics devices must meet several established technical requirements. Here are some of the standards that must be met:
Power Supply
Free Space Optics Telecommunication Equipment can be supplied with either AC or DC power. For devices with an AC power supply, the device must operate normally with 220V of approximately 10% and 50 Hz of approximately 2% frequency. In the case that the device uses an external power source, such as an AC adapter, that supply must not affect the device’s operability.
Electromagnetic Compatibility (EMC)
EMC measurements on FSO are divided into two, namely, emission and immunity measurements. The following is an explanation of the measurements.
- EMC Emission: Measurements for OLT devices and ONT/ONU devices refer to SNI ISO/IEC CISPR 32.
- EMC Immunity: For now there is no specific regulation governing this, in the future there will be a Ministerial Decree that will regulate this.
Electrical Safety
The electrical safety assessment of FSO telecommunication equipment must meet the requirements specified in SNI IEC 62368-1:2014 or the newest, SNI 60950-1:2016 or the newest, IEC 62368-1, or IEC 60950-1.
Laser Safety
- Lasers used for uplink (point to point) purposes: Must meet class 1, 1M, 2, 2M, 3R, and/or 3B standards in accordance with IEC 60825-1 and/or IEC 60825-12.
- Lasers used in optical interfaces for data purposes lines interface: Must meet class 1 or class 1M standards according to IEC 60825.
Interoperability Interface Requirements
The FSO telecommunication equipment system consists of Ethernet and SDH with the following conditions:
- Ethernet: The Ethernet interface must comply with the relevant IEEE 802.3 standard.
- SDH: In the event that the device has an interface with SDH technology, the interface characteristics must comply with one or more protocol types STM-16 (ITU-T Rec G.957) and/or STM-64 (ITU-T Rec G.691) with the specifications on Table 3, Table 4, Table 5, and/or Table 6.
Free Space Optics Certification Process in Indonesia
For Free Space Optics Telecommunication Equipment to be used legally in Indonesia, certification from DJID is required. Here are the steps to get it:
Pre-testing the device
Before official testing, the device must be pre-tested first using measuring equipment such as a spectrum analyzer.
This helps ensure devices meet technical standards before being tested in authorized laboratories.
Testing at an official laboratory
After passing the pre-testing, the gadget will be sent to an assigned official research facility for experience testing according to the guidelines stipulated in the Ministerial Decree of the Ministry of Communication and Digital No. 43 Tahun 2025.
Issuance of certificates
After the device passes testing, an official certificate will be issued by DJID. This certificate is a requirement to market the device legally in Indonesia.
Tips to ensure standards compliance
- Learn the latest regulations: Make sure you understand every detail of the Ministerial Decree of the Ministry of Communication and Digital No. 43 Tahun 2025, including technical requirements and test methods.
- Perform pre-testing: Before official testing, perform pre-testing to ensure the device meets standards. If you don’t have a measuring instrument, use the DJID certification service, which provides pre-testing services.
- Counsel a master: If this is your to begin with time looking for certification, consider utilizing the services of experienced DJID certification administrations.
