Features of Passive Electronic Locks and Application of The Telecommunications Industry

Passive electronic locks are passive and key-powered for the lock; the lock does not require power supply and communication wiring, and can be used on a variety of devices.


The lock adopts a standard size design, which is fully compatible with the installation method of traditional locks.

The lock and the key are respectively integrated with a smart chip, and the 64-bit ID identification code is used for encryption, so that the electronic key cannot be copied, ensuring the security of the lock.
The lock core has a built-in storage chip, which can record on-site electronic lock operation information, and trace the specific time and which key has been operated.
The electronic key adopts process-based authorization management to strictly control the operation authority and operation time of the electronic lock. Even if the key is lost, it is only necessary to set the lost status without changing the lock.
Passive electronic locks can achieve up to IP68 protection level, waterproof and dustproof, and can work in various harsh environments such as high and low temperatures and humidity.
One lock can authorize multiple keys, and one key can also be used for any number of passive electronic locks.

System composition

The system is mainly composed of three parts: management software, electronic key, passive electronic lock.


It is widely used in electric power, telecommunications, railway, industry, logistics and other related industries.

Telecom industry application cases 

With the development of social economy and technological progress, the communication industry has also achieved unprecedented development. The optical fiber transmission network has also entered a stage of rapid development. There are more and more optical cable transfer boxes. How to manage these boxes effectively and scientifically Body has always been a problem faced by operators.

The following problems have always existed in the actual application of the optical cable transfer box:

  • The current optical cable transfer box design mainly adopts mechanical lock, which is easy to be opened maliciously;
  • There are many keys, which can easily cause management confusion;
  • The use of networked monitoring methods is technically difficult, the equipment investment is large, and the necessity is small;
  • There is no power supply inside the optical cable transfer box, which makes it very difficult to achieve access control management;

In view of the above points, the emergence of passive electronic locks provides the possibility to solve these problems, combining mobile phone APP, electronic key, and system management platform. On the one hand, the practicability of the lock of the optical cable transfer box is improved to prevent technical opening; on the other hand, the scientific management of the unlocking of the optical cable transfer box is strengthened and standardized, which helps to establish the management and supervision mechanism of the unlocking behavior of the company’s internal personnel.
