The DDM, DOM and RGD in OEMfibers SFP Transceiver Models
If it's your first buy of Cisco SFP transceivers , you might be very confused with the fuction options “DDM”, “DOM” or “RGD”. So, what functons do they represent? And do you will need these functions? Today, we could have a detailed explanation of these.
What’s DDM?
DDM, namely Digital Diagnostics Monitoring, is a technology found in SFP transceivers to be able to give the end user the ability to monitor real-time parameters of the SFPs. Such parameters include optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage etc.
What’s DOM?
DOM, short for Digital optical monitoring, knows the DDM function. Additionally it is a feature that allows you to monitor many parameters of the transceiver module in real-time. DOM gives you to monitor the TX (transmit) and RX (receive) of the module, aswell as input/output power, temperature, and voltage. Network administrators may then check and make sure that the module is functioning correctly.
Author Note: Obviously a SFP with DDM/DOM funstion is high-ender than one which without it. For this reason the majority of modern optical SFP transceivers support DDM/DOM functions according to the industry-standard SFF-8472.
What’s RGD?
You might be confused with the difference with the SFPs with “RGD” and the one without it, or you may be thinking about the “-RGD” in the merchandise number of some SFP transceiver modules. So, what does RGD are a symbol of? RGD means rugged transceivers. In fact, these are enhanced transceiver modules which were created for greater durability, and may operate under more extreme conditions. Rugged transceivers may feature improved ESD protection, and extended operating temperature range to ensure that it can help get rid of field failures with no need of costly external protection devices.
Other Functions in SFP transceivers
If you have an event of shopping for Cisco SFPs, you might be confused with the part number with “=”, because you can't get out the difference with the main one without “=” based on the specification. Actually, “=” can be called a “FRU” part where FRU means “Field Replaceable Units”. Those will be the parts that can be utilized as “spare” or be shipped individually to displace damaged units. However the new parts that are ordered directly from a reseller or from Cisco usually don’t include the = sign. Thus, if you would like to get an SFP transceiver with the “FRU” part, you should ask your vendor to make sure this function.Read even more:https://www.oemfibers.com/sfp-transceivers-c-16_36/
