The doctor would diagnose our condition when we were sick, Digital diagnostic monitoring (DDM) that the article was mentioned like a doctor to monitor the condition of optical transceiver. What is Digital Diagnostic Monitoring (DDM)? What can Digital Diagnostic Monitoring do? These answers will be to find in this article.
What Is Digital Diagnostic Monitoring (DDM)?
Digital Diagnostic Monitoring is followed by the (MSA) SFF-8472. This specification provides a common reference for systems manufacturers, system integrators, and suppliers. The main advantage is that a reference frame is defined for optical transceiver manufacturers and network equipment manufacturers, to ensure optical transceivers which allow real time access to device operating parameters. This technology allows the user to monitor real-time parameters of the fiber optic transceivers, like optical input/output power, temperature, laser bias current, and transceiver supply voltage, etc.
What Can Digital Diagnostic Monitoring Do?
DDM function can provide component monitoring on transceiver applications in details. And DDM interface includes a system of alarm and warning flags which alert the host system when particular operating parameters are outside of a factory set normal operating. Thus, DDM interface can also enable the end user with the capabilities of fault isolation and failure prediction.
The DDM enables the end user to monitor key parameters in the performance of the fiber optic transceiver including the following:
Transceiver supply voltage
Optical input power
Optical output power
Laser bias current
The real-time diagnostic parameters can be monitored to alert the system when the transceiver’s specified operating limits are exceeded and compliance cannot be ensured. DDM can help to ensure that the business can be proactive in preventative maintenance of the network and ensure business continuity. And it would easy to explain why modern transceivers are with DDM. It is irresistible development trend of industry and technology.
When buy fiber optical transceiver today, you will have the option with or without DDM. And most of the modern transceivers are with the DDM function. The optical transceivers with DDM are much popular than those without DDM. Gigalight is an innovative enterprise to innovate product design, to satisfy the customers’ needs, optical transceivers with DDM are provided by Gigalight.
