Many people are not clear about the difference between sfp and sfp+, so sometimes it brings unnecessary trouble. 10G module has gone through the development from 300Pin, XENPAK, X2, XFP, and finally realized the same size as SFP to transmit the 10G signal, which is SFP+. SFP meets the demand of high density of optical module by its miniaturization and low cost, so what are the types of 10G SFP+ optical modules? What are the types of 10G SFP+ optical modules?

1、10G SFP+ SR Optical Module

10GBase-SR is one of the Ethernet specifications, 10G SFP+ SR optical module conforms to this standard specification, and this optical module model in the SR is a short range (Short Range), which means that it and multimode fiber together with the transmission distance up to 300 m. In addition, 10G SFP+ SR optical module wavelength is 850nm, with a low cost, low power consumption and size of the optical module, the 10G SFP+ SR optical module has the advantage of low cost, low power consumption and high density. advantages of low cost, low power consumption and small size and high density.

2、10G SFP+ LRM Optical Module

10G SFP+ LRM optical modules comply with 10GBase-LRM Ethernet specification, where LRM refers to Long Reach Multimode. 10G SFP+ LRM optical modules can be used with OM1, OM2, and OM3 multimode optical fibers, and are mainly used in FDDI networks and 10G data communications, with low power consumption and excellent EMI performance. Its low power consumption and excellent EMI performance are also fully compliant with the MSA SFF-8431 standard. In addition, the upgraded version of 10G SFP+ LRM optical module is SFP-10G-LRM2 optical module, the transmission distance of this upgraded optical module can reach up to 2km, which is commonly used in LAN connection.

3、10G SFP+ LR Optical Module

10G SFP+ LR optical modules comply with the 10GBase-LR Ethernet specification, in which LR refers to the long distance (Long Range), in the wavelength of 1310nm single-mode fiber on its transmission distance is up to 10km, in fact, up to 25km, but also has the advantages of miniaturization, low-power consumption, long transmission distance.

4、10G SFP+ ER Optical Module

10G SFP+ ER optical module meets the 10GBase-ER Ethernet specification, of which ER is the meaning of Extended Range, its wavelength is 1550nm, and single-mode fiber together with the transmission distance of up to 40km, is a very cost-effective ultra-long-distance optical module, is currently in the data center and enterprise parks are very popular.

5、10G SFP+ ZR Optical Module

10G SFP + ZR optical module in line with the 10GBase-ZR Ethernet specification, but this specification belongs to the Cisco proprietary. 10G SFP + ZR optical module model in the ZR refers to the longest distance (Ze best Range), which shows that the transmission distance of this optical module is very far, and single-mode fiber together with a maximum transmission distance of up to 80km, so this optical module is very widely used. module is widely used.

6, 10G SFP + BIDI optical module

BIDI optical module is a single-fiber bi-directional optical module, this optical module has SFP and SFP + two packaging methods, the main difference is that the rate of BIDI SFP + optical module is 10G, BIDI SFP optical module rate is one hundred megabytes or gigabytes. BIDI SFP + optical module using WDM technology, and there are two fiber optic jacks, which need to be used in pairs in order to ensure normal operation. However, the benefit of this optical module is that it can reduce the amount of fiber used in network deployment, thus greatly reducing the cost of network deployment.

7、10G SFP+ CWDM Optical Module

10G SFP+ CWDM optical module is a kind of coarse wavelength division multiplexing (CWDM) optical module, which is usually used together with single mode fiber. This optical module saves fiber resources by using CWDM technology, which can significantly improve the flexibility, economy and reliability of the network, and the power consumption of this optical module is very small, which is 12.5% of 10G SFP+ DWDM optical module.

8, 10G SFP + DWDM optical modules

10G SFP+ DWDM optical module is a rare domestic high speed rate, high capacity dense wavelength division multiplexing optical module, usually used together with single mode fiber, transmission distance up to 80km, suitable for long distance data transmission. This kind of optical module can maximally meet the demand for ultra-large capacity and ultra-long distance transmission, provide stable guarantee for multi-service operation and future network upgrade and expansion, also support a variety of networking modes, and wavelength scheduling can also be carried out between the nodes, which has a variety of advantages, such as easy expansion of capacity, flexible service access, high bandwidth utilization and high reliability.

9、10G Port Module

10G electrical interface module is an encapsulated form of SFP + photoelectric conversion module, the interface type is RJ45, usually used together with ultra-six or seven types of network patch cords, the shortcomings of this optical module does not support the DOM function, and the transmission distance is 30m, because the scope of application is not wide enough.
