DDM interface can also enable end users to have the ability of fault isolation and fault prediction, and optical fiber transceiver with DDM helps to ensure that services can actively prevent network maintenance and ensure business continuity.
Extended data:
SFP+ and SFP
1, SFP and SFP+ have the same overall dimensions;
2.SFP protocol specification: IEEE802.3, SFF-8472;;
SFP+ and XFP
1, SFP+ and XFP are all 10G optical fiber modules, which can interoperate with other types of 10G modules.
2. Due to its small size, SFP+ has signal modulation function, serializer/deserializer, MAC, clock and data recovery (CDR) and electronic devices.
The dispersion compensation (EDC) function is moved from the module to the motherboard card;
3. The agreement that XFP abides by: XFP maritime agreement;
4. Protocol followed by SFP+:IEEE? 802.3ae、SFF-843 1、SFF-8432;
5.SFP+ is a mainstream design.
SFP+
1, SFP+ is more compact than X2 and XFP (same size as SFP);
2. It can be directly connected with XFP, XFP, X2 and Sempak of the same type;
3. Products with lower cost than XFP, XFP, X2 and Sempak.
