What kind of product does the SR/LR/ER/ZR specification of 10G SFP

resource

When we are looking for 10G sfp, we have the four most common descriptions of 10GBase-SR, 10GBase-LR, 10GBase-ER and 10GBase-ZR. Which four describe which SFP+ optical module is represented in the Ethernet specification? Let us take a look at the different optical modules represented by different descriptions today. The 10G SFP+ dual-fiber series optical modules include SR, LRM, LR, ER, and ZR modules. Their interface types are LC duplex and comply with IEEE802.3ae, SFF-8472, and SFF-8431 standards. The following are the specific details of these optical modules. 1, 10G SFP+ SR optical module The 10G SFP+ SR optical module complies with the 10GBase-SR Ethernet specification, and the SR in this optical module model means short range, which means that it can be used with multimode fiber for transmission distances up to 300m. . In addition, the 10G SFP+ SR optical module has a wavelength of 850nm, which has the advantages of low cost, low power consumption, small size and high density. 2, 10G SFP+ LR optical module The 10G SFP+ LR optical module complies with the 10GBase-LR Ethernet specification, where LR refers to the Long Range and its transmission distance is up to 10km on a single mode fiber with a wavelength of 1310nm, which can actually reach up to 25km. It also has the advantages of miniaturization, low power consumption and long transmission distance. 3, 10G SFP+ ER optical module The 10G SFP+ ER optical module complies with the 10GBase-ER Ethernet specification. The ER is the Extended Range. It has two wavelengths of 1550nm and 1310nm respectively. The transmission distance can be reached when used with single-mode fiber. 40km, it is a very long-distance optical module with very high cost performance. It is currently favored in data centers and enterprise parks. 4, 10G SFP+ ZR optical module The 10G SFP+ ZR optical module complies with the 10GBase-ZR Ethernet specification. The ZR in the 10G SFP+ ZR optical module model refers to the longest distance (Ze best Range). It can be seen that the transmission distance of this optical module is very far. The maximum transmission distance when using the single mode fiber with the wavelength of 1550nm can be used. Up to 80km, this kind of optical module is widely used.
