In the world of fiber optic communications, we often hear the terms "optical module encryption" and "write code", especially in the products of large network equipment manufacturers. In this article, we'll take a look at optical module write codes!

Optical transceiver module writing refers to the process of programming or modifying the internal storage area of the optical module through a specific device (writer/writer board).MSA organization defines the software and hardware interfaces of the optical module, and different manufacturers design and produce the optical module according to the same protocol, so the writing area inside the module of different manufacturers is the same.

Optical modules usually contain two write code areas of 128 bytes each, which are used to store key data such as vendor information, model number, serial number, DDM (Digital Diagnostic Monitoring) information and compatibility codes. The correctness and integrity of this information is critical to the proper functioning of the optical module in the device.

A code writer board is a specialized device necessary for optical module manufacturers to program optical modules. Theoretically, the code writer can modify any optical module code that complies with industry standards, but unauthorized modifications may result in the loss of the code or the inability of the optical module to function properly due to the password protection mechanism set by the manufacturer.

Optical modules are connected to network equipment such as switches through the IIC (Inter-Integrated Circuit) bus, and the equipment determines whether an optical module is compatible or whether it is an original module by reading the information in its write code area. The write code board then programs the optical module through the same interface to modify or update the code.

ETU-LINK, as a source manufacturer of optical modules, has been deeply engaged in the optical communication industry for more than ten years. Before products leave the factory, they are tested on switches for compatibility and compatibility verification is completed.

In order to meet the needs of customers who need to re-write code after purchasing bulk modules that will be applied to different devices, ETU-LINK has introduced SFP/XFP/SFP+/QSFP/QSFP112/QSFP-DD/OSFP and other writing boards with different interfaces and rates, which support up to 400G(400G optical modules) transmission rate and greatly reduce the cost difference caused by the ports.

ETU-LINK's writing boards are compact and highly compatible, easy to carry and transport; they are designed with original open molds and have exquisite appearance; they have adjustable functions, which are convenient for users to change and adjust the channels; they can be read directly without installation, which is convenient and quick. It can realize the function of reading and writing various compatible codes, and optimize the function of batch operation in a large number of practices, so that customers can conveniently do code writing operation on the optical module on hand.
