DDM, or digital diagnostic monitoring, is a technology used in SFP optical modules to enable users to monitor real-time parameters of SFPs. These parameters include optical output power, optical input power, temperature, laser bias current and transceiver power supply voltage. The DDM interface is an extension of the serial ID interface defined in the GBIC specification and the SFP MSA.
The DDM interface can also enable the end user to have the ability of fault isolation and fault prediction. The optical transceiver with DDM can help ensure that the business can actively prevent network maintenance and ensure business continuity.
What is DOM?
DOM, the abbreviation of digital optical monitoring, is also a function that allows you to monitor all aspects of the data of the optical module in real time, such as the sending and receiving, input and output power, temperature, and voltage of the optical module. The network administrator can check these data to ensure that the optical module works normally.
Obviously, SFP optical modules with DDM/DOM functions are better than optical modules without these functions. Therefore, most SFP optical modules comply with SFF-8472 standards and can support DDM/DOM functions.
What is RGD?
RGD means a solid optical module, so the optical module with RGD function is an enhanced optical module, which is more durable and can be used under very bad conditions. Rugged optical modules have enhanced anti-static protection and a wider range of operating temperatures, eliminating field faults without the need for expensive external protection equipment.
It should be noted that the rugged SFP optical module can be identified by its product model, and the specific situation of RGD depends on the specific supplier.
