Its low power consumption and excellent EMI performance are also fully compliant with MSA SFF-8431 standards.

3、10G SFP+ LR Optical Module

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

4、10G SFP+ ER Optical Module

10G SFP+ ER optical module meets the 10GBase-ER Ethernet specification, in which ER is the meaning of ultra-long distance (Extended Range), it has two wavelengths, respectively, 1550nm and 1310nm, and single-mode fiber together with a transmission distance of up to 40km, it is a cost-effective ultra-long-distance optical module, is currently in the data center and the enterprise park is very popular. It is a very cost-effective ultra-long-haul optical module, which is currently favored in data centers and enterprise parks.

5、10G SFP+ ZR Optical Module

10G SFP+ ZR optical module meets the 10GBase-ZR Ethernet specification. 10G SFP+ ZR optical module model ZR refers to the longest distance (Ze best Range), which shows that the transmission distance of this optical module is very far, in the wavelength of 1550nm single-mode fiber together with a transmission distance of up to 80km, so this module is widely used. Therefore, this kind of optical module is widely used.

10G SFP + series optical modules also include SFP + CWDM, SFP + DWDM and SFP + BIDI (single fiber bidirectional).

SFP+ CWDM Optical Module

The 10G SFP+ CWDM optical module is a coarse wavelength division multiplexing (CWDM) optical module that is typically used with single-mode fiber. This optical module saves fiber resources by adopting 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 that of 10G SFP+ DWDM optical module.

SFP+ DWDM Optical Module

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

SFP+ BIDI Optical Module

10G SFP+ BIDI optical module is a single-fiber bi-directional optical module, the use of WDM technology, need to be used in pairs to ensure normal operation, but the benefits of this optical module is to reduce the amount of optical fiber in the deployment of the network, thus greatly reducing the cost of network deployment.
