The optical modules and Ethernet switches are indispensable in enterprise networks and the construction of data centers. Optical modules are mainly used to convert the electrical signal to optical signal, while Ethernet switches play the role of forwarding those signals. Among the various optical modules, the SFP+ module is one of the most used modules, which can be used with Ethernet switches to achieve different network requirements through different ways of connection.

WHAT IS THE SFP+ MODULE?

The SFP+ module belongs to the SFP module and is designed to support up to 10Gbps, which is independent of the communication protocol. Generally, this module connects with a switch, fiber router, fiber NIC, etc. And it is used in 10Gbps Ethernet and 8.5Gbps Fibre Channel systems, which can meet the demand for higher rates in data centers and enable network expansion and conversion in data centers.

With high density and small size, SFP+ optical modules line card can interoperate with other types of 10G modules, providing higher installation density and cost savings for data centers. As a result, it has also become the mainstream pluggable optical module in the market.

Types of SFP+ modules

In general, SFP modules are classified according to practical applications, and the common ones are 10G SFP+, BiDi SFP+, CWDM SFP+, DWDM SFP+.

10G SFP+ MODULE

Common SFP+ module can be regarded as an upgraded version of 10G SFP module, is the mainstream design in the current market.

BiDi SFP+ MODULE

This type of optical module uses wavelength division multiplexing technology and can reach a rate of 11.1G bps with low power consumption. And it allows to transmit and receive data to/from interconnected network devices (like network switches or routers) via a single optical fiber, which enables users to simplify their cabling system, increasing network capacity and reducing cost.

CWDM SFP+ MODULE

Advantages

Scalability and Flexibility—CWDM SFP+ modules can support multiple channels. It means that more channels can be activated as demand increases. CWDM SFP+ modules have a wide variety of network configurations that range from the meshed-ring configurations to the multi-channel point-to-point. In point-to-point configurations, the two endpoints will connect directly through a fiber link, allowing users to add or delete as many as eight channels at a time.

Low Risks in Investment—Most CDWM SFP+ modules have a low failure rate, which is less likely to be the reason why the user’s solution fails. It helps enterprises increase the bandwidth of Ethernet optical infrastructure without adding any additional fiber strands and can also be used in conjunction with other SFP+ devices on the same platform. Thus the user will be able to re-invest the capital saved by avoiding prematurely failed devices.

In addition, CWDM SFP+ module adopts coarse wavelength division multiplexing technology and is often used with single-mode fiber, which can save fiber resources, be more flexible and reliable in networking, and consume less power. And it has been applied in scalable and flexible large enterprises and data center deployment.

DWDM SFP+ MODULE

Different from CWDM SFP+ module, DWDM uses denser channel spacing, which allows for more wavelengths to be used on a single fiber. DWDM is typically used in large optical networks over the longer distance. Thus if you are looking for SFP+ modules over long distance and with better scalability, DWDM SFP+ module is the ideal choice.
