Through an official announcement on e-Sertifikasi page, DJID officially announced the new technical regulation of KEPMEN KOMDIGI No. 43 year 2025 regarding the technical standards for free space optics telecommunication devices. This new technical regulation has come into effect since 18 May 2025. With the provision of this minister decree, the previous technical regulation of KEPMEN KOMINFO No. 59 year 2022 for the same standards is revoked and declared invalid.
In this article we will discuss all about new regulation for free space optics telecommunications device and its impact on ongoing applications.
Definition of free space optics telecommunication device
Before we do further discussion about this new regulation, do you know what free space optics telecommunication device is? Free space optics (FSO) telecommunication device is a device that uses light transmission in the air to transmit information with point-to-point and line-of-sight configurations.
This technology works on the principle of a direct connection between two points that have a line of sight. As long as there are no obstacles, such as buildings or trees, between the transmitter and receiver, information can be sent quickly using light. Below is an example of free space optics telecommunications device configuration.

Technical requirement for free space optics telecommunication device
Technical assessment for certification of free space optics telecommunication device is proven through several tests, as follows:
- Power supply
- Electromagnetic compatibility (according to CISPR 32 and CISPR 35)
- Electrical safety (according to IEC 62368-1 or IEC 60950-1)
- Laser safety (Laser class 1, 1M, 2, 2M, 3R and/or 3B, according to IEC 60825-1 & IEC 60825-12)
- Synchronous digital hierarchy interface requirements
- Statement of conformity to the IEEE 802.3 standard for ethernet interface requirements
For free space optics telecommunication devices that own laser classes 2, 2M, 3R, and/or 3B, it must submit following additional documents:
- Letter of cooperation agreement between the certificate applicant and the telecommunications network provider in Indonesia.
- Statement signed by the certificate applicant stating that they will not sell free space optics telecommunications devices other than to telecommunications network providers.
Laser safety requirements for free space optics telecommunication device

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 on optical interfaces for data lines interface purposes must meet class 1 or class 1M standards in accordance with IEC 60825. Following are laser classification based on standard of IEC 60825:
| Laser Class | Specification |
| Class 1 | Class 1 is a type of laser with very low power. This type of laser is the safest laser with low output power (0.4 µW for blue) and has no threat to human eyes and skin. |
| Class 1M | Class 1M is still classified as a type of laser with very low power. This laser class classifies laser beams are not safe when viewed with magnifying lenses. |
| Class 2 | Class 2 is a type of laser with visible low power lasers. Direct eye contact with lasers class 2 and the reflections from them should be avoided. Workplaces that use class 2 lasers should be labeled with warnings. Our natural blink response also protects us from exposure. |
| Class 2M | Class 2M is still classified as a type of laser with visible low power lasers. This type of laser is generally safe, but do not view it through any optical device. Unlike class 1M lasers, our blink response will not protect our eyes, and even the slightest exposure can cause eye injury. |
| Class 3R | Class 3R is classified as low power lasers. Viewing lasers class 3R can be harmful to the eyes, and direct exposure can damage the skin. |
| Class 3B | Class 3B is classified as medium power lasers. Reflection from lasers class 3B is the same dangerous as direct contact. Therefore, proper precautions are needed when working with these type of lasers. |
| Class 4 | Class 4 lasers are classified as high power lasers. This type of laser is the most dangerous and deadly. The output power of this class is greater than 500 mWatt. The radiation can be visible, invisible, or in the infrared range. Direct and indirect exposure can cause severe skin burns or blindness. |
Placement of free space optics telecommunications device
The placement location of free space optics telecommunication device based on laser safety requirement will determine the permitted access level and emissions used with the following provisions:
- Unrestricted location: an open location where access to transmitter/receiver equipment of FSO telecommunication device and laser beams is not restricted and can be accessed by the general public.
- Restricted location: a limited location where access to transmitter/receiver equipment of FSO telecommunication device and laser beams is restricted and cannot be accessed by the general public.
- Inaccessible location: a volume of space that has a horizontal distance of > 2.5 meters from the unrestricted location and vertically > 6 meters above ground level, and > 3 meters above ground level at the restricted location.
- Controlled location: a limited location where there are restrictive measures carried out through administrative controls or certain measurable techniques so that the FSO telecommunication device location cannot be accessed except by authorized officers who have laser safety training.
Treatment for ongoing DJID applications
Ongoing DJID applications with test reports of free space optics telecommunication devices that have been issued before this minister decree comes into effect may still be accepted to fulfill the requirements of DJID certification as long as the test reports do not conflict with this new regulation.
