Enterprise network deployment and data center construction are inseparable from optical module and switche. Optical module is mainly used to convert electrical signals to optical signals, while switche is used to forward photoelectric signals.
Among the many optical modules, the 10G SFP+ optical module is one of the most used optical modules at present. It adopts different connection methods when used with switche, to achieve different network requirements.
The 10G SFP+ optical module is a 10G optical fiber module belonging to the SFP optical module, which is independent of the communication protocol.
It is generally connected with switches, fiber routers, fiber network cards, etc., and is used in 10G bps Ethernet and 8.5G bps fiber channel systems to meet the higher rate requirements of data centers and realize network expansion and conversion in data centers.
The SFP+ optical module line card has a high density and small size and can be intercommunicated with other types of 10G modules. 10G SFP+ transceiver provides data centers with higher mounting density and cost savings, and thus becomes the mainstream pluggable optical module in the market.
More information can be found in optical transceiver wiki.
Under normal circumstances, SFP+ optical modules are classified according to practical applications, and the common types are 10G SFP+, BIDI SFP+, CWDM SFP+, and DWDM SFP+.
The 10G SFP+ optical module is the common SFP+ optical module, and it can also be regarded as an upgraded version of the 10G SFP optical module, which is the mainstream design in the current market. And we also have intel 10g sfp+ for sale.
BIDI SFP+ is a single-fiber bidirectional optical module with a rate of 11.1G bps and low power consumption. A module has an optical fiber jack, which is generally used in pairs. The use of optical fibers can be reduced and the construction cost can be reduced during network construction in the data center.
CWDM SFP+ optical module adopts coarse wavelength division multiplexing technology, which is often used in combination with single-mode fiber, which can save fiber resources, and is more flexible and reliable in networking, and has low power consumption.
DWDM SFP+ optical module adopts dense wavelength division multiplexing technology, which is mostly used in long-distance data transmission with a maximum transmission distance of 80km. It has the characteristics of high speed, large capacity and strong scalability.
As a professional 100g qsfp28 supplier, we are pleased to share with you that different types of optical modules are connected to switches and can be used in different networking schemes. The following introduces several practical application solutions of SFP+ optical modules and switches.
1. The connection between the 10G SFP+ 10G optical module and the switch
Insert four 10g SPF+ optical modules into the 10-Gbps SFP+ port of one switch in turn, then insert a 40G QSFP+ optical module into the 40-Gbps QSFP+ port of the other switch, and finally insert a branch fiber jumper in the middle to connect.
This connection method mainly realizes the expansion of the network from 10G to 40G, which can quickly and easily meet the network upgrade requirements of the data center.
2. The connection between the BIDI SFP+ 10 Gigabit single-fiber bidirectional optical module and the switch
Insert the optical modules into the SFP+ ports of the two switches respectively, and then connect the optical modules on the two switches with the LC fiber jumpers corresponding to the optical module connection ports.
This connection method effectively realizes the simplest and most economical data connection, and can be applied to the Ethernet connection of data centers, enterprise wiring and telecom operation transmission.
3. The connection between the CWDM SFP+ 10 Gigabit optical module and the switch
This connection method uses relay boxes, optical fiber transceivers, CWDM coarse wavelength division multiplexers, etc., to connect the optical module with the switch, which can convert the RJ45 electrical port on the 10G 10 Gigabit Ethernet switch to CWDM coarse wavelength division multiplexer.
4. The connection between the DWDM SFP+ 10 Gigabit optical module and the switch
Insert the optical module into the SFP+ port of the switch, and then connect it with the DWDM dense wavelength division multiplexer with an armored fiber jumper.
This connection method realizes the protection of optical signals in long-distance transmission, can minimize optical wave loss, and is suitable for long-distance optical signal transmission.
Equipment manufacturers of optical modules will encrypt their devices to varying degrees, also known as compatibility. Modules of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical modules. Compatibility manufacturers need to conduct different compatibility adaptations on the optical modules. Whether or not they can perfectly solve compatibility issues is particularly important.
