In modern Internet era, optical transceiver modules and fiber network switches are indispensable for enterprise network deployment and data center construction. Optical transceiver modules are used for converting electrical signal and optical signal, while fiber network switches are used for electrical (optical) signal forwarding. Common optical transceiver modules include SFP, SFP+, XFP, SFP28, QSFP+ and QSFP28, among which SFP+ optical modules are the most widely used, connected with fiber network switch to realize different network requirements.
SFP+ Optical Transceiver Module
SFP+ optical module is a kind of 10G optical module of SFP optical module, which is independent of communication protocols. Generally it is connected with fiber network switch, fiber optic router or fiber NIC card, to be applied in 10G bps Ethernet and 8.5G bps Fiber Channel, to meet the higher speed rate requirements of data centers, realizing network expansion and conversion.
SFP+ optical modules feature high density and compact size, which can interoperate with other kinds of 10 Gbps optical modules, providing higher installation density and cost efficiency for data centers. Therefore, it has become the mainstream pluggable optical module in current market.
SFP+ Transceiver Modules for Different Fiber Network Switches
Common types of SFP+ optical modules include 10G SFP+, 10G BIDI SFP+, CWDM SFP+, and DWDM SFP+, according to their applications. Different types of optical modules connected with fiber network switches can be used in different networking solutions.
10G SFP+ Optical Module for 40G Fiber Network Switch
This is the mainstream SFP+ optical module in the current market, with the farthest transmission distance up to 100 km. It can also be regarded as the upgraded version of 1G SFP optical module.
Plug four 10G SFP+ optical modules into the 10-Gbps SFP+ ports of a fiber network switch, then insert a 40G QSFP+ optical module into the 40-Gbps QSFP+ port of the other fiber network switch, and finish by connecting the two optical modules with a breakout fiber patch cable. This solution realizes the network expansion from 10G to 40 G, which can quickly and conveniently meet the network upgrade demand of data centers.
10G BIDI SFP+ Optical Module for 10G Fiber Network Switch
It adopts WDM (Wavelength Division Multiplexing) technology, with maximum rate of 11.1Gbps and low power consumption. It is usually used in pairs, with longest transmission reach up to 80 km. Its application in the network construction of data cent can help reduce the usage of optical fibers and construction costs.
Plug the 10G BIDI SFP+ single mode optical Module into the SFP+ ports of two fiber network switches, and connect them with LC fiber patch cables. This solution effectively realizes the most simple and economical way of data connection, which can be applied to the Ethernet connection of data center, enterprise wiring and telecommunication operation transmission.
