How to Use SFP Optical Modules with Switches

As we all know, many companies want to carry out network deployment, and their data center construction is also inseparable from optical modules and switches. What is the main function of optical modules? It is mainly used to transform electronic signals and light signals, and network switches have the effect of sharing optical and electronic signals. Among many optical modules, SFP optical module is one of the most commonly used optical modules at present. Different interface modes can be used to complete different Internet requirements when it is used with network switches.

Definition of SFP optical module

SFP optical module is a 10G fiber module that belongs to SFP optical module and is used for communication protocols. Usually, it is connected with network switches, fiber routers, fiber NICs, etc. It is used in 10Gbps Ethernet interfaces and 8.5Gbps fiber line security channel software. It can reach the high-speed requirements of large data centers and complete the Internet expansion and transformation of large data centers.

SFP optical module has a high relative density and small size of line cards. It can communicate with other types of 10G control modules, providing a high installation relative density for large data centers, saving costs, and becoming a popular pluggable optical module on the sales market,  with the 10G SFP manufacturer meeting the ever-growing demand.

Application of SFP optical module with network switches

Connecting different types of optical modules with network switches can be used in different network schemes. The following are specific application plans for several types of SFP+ optical modules and network switches.

Plan one: The connection between 10GSFP+ 10 Gigabit optical modules and network switches

Insert four 10GSFP+ optical modules in the 10-GbpsSFP+ port number of a network switch, and then insert a 40GQSFP+ optical module in the 40-GbpsQSFP+ port number of another network switch. Finally, connect them with a fiber optic cable. This connection method completes the expansion from 10G to 40G of the Internet, and can quickly and easily meet the network upgrade requirements of large data centers.

Plan two: The connection between BIDISFP+ 10 Gigabit optical modules and network switches

Insert the optical modules separately into the SFP+ port numbers of the two network switches, and then connect the optical modules on the two network switches with LC fiber optic cables that match the optical module interface. This connection method provides a very simple and economical data information connection, which can be used in Ethernet interface connections of large data centers, company wiring, and telecom networks.

Plan three: The connection between CWDMSFP+ 10 Gigabit optical modules and network switches

This connection method uses wireless routers, fiber optic transceivers, CWDM multiplexers, etc. to connect optical modules with network switches, and finally can achieve the CWDM wavelength required by the CWDM multiplexer from the R45 electrical port of the 10G Ethernet switch. This is why businesses and enterprises frequently look towards a reliable and experienced DWDM SFP supplier to meet their optical module needs while maintaining the highest standards of quality.

Plan four: The connection between DWDMSFP+ 10 Gigabit optical modules and network switches

Insert the optical modules into the SFP+ port numbers of the network switch and then connect them with armor cable fiber optic cables to connect them to the DWDM dense wavelength division multiplexer. This connection method completes the maintenance of the unlit optical signal in long-distance transmission, which reduces the optical wave loss to a large extent and is suitable for long-distance unlit optical signal transmission.

Common problems when connecting SFP optical modules with network switches

• Pay attention to whether the optical module wavelengths and transmission distances used on both sides of the network switch are the same, and whether the single fiber and double fiber, single mode and multimode fiber problems are the same. If there is an unequal situation, correspondingly using a converter.

• When using optical modules, try to minimize static induction and bumps. If bumps occur, it is not recommended to use the optical module again.

• Pay attention to the positive and negative sides of the optical module when inserting it, and the cap and label should face up.

• When inserting optical modules into network switches, try to push them to the bottom as much as possible. There will generally be a slight vibration after insertion. After insertion, you can gently pull the optical module to check whether it is installed in time.

• When disassembling the optical module, first drag the smart bracelet to a position 90° with the optical switch, and then pull out the optical module.
