Q、Varieties of 10G SFP+ Optical Modules

A、Commonly, SFP+ optical modules are categorized based on their practical applications. The typical types include 10G SFP+, BIDI SFP+, CWDM SFP+, and DWDM SFP+.

• 10G SFP+ Optical Module

This module is essentially the standard SFP+ module, functioning as an upgraded version of the 10G SFP module. It is currently the mainstream design in the market.

• BIDI SFP+ Optical Module

Utilizing wavelength division multiplexing technology, this module can achieve rates up to 11.1Gbps with low power consumption. With two fiber ports intended for paired use, it reduces fiber requirements during data center network deployment, thereby lowering construction costs.

• CWDM SFP+ Optical Module

Employing coarse wavelength division multiplexing, this module is commonly paired with single-mode fiber, economizing on fiber resources and offering greater flexibility, reliability, and low power consumption in network architecture.

• DWDM SFP+ Optical Module

Adopting dense wavelength division multiplexing, this module is frequently used for long-distance data transmission, with a maximum transmission distance of up to 80km. It features high speed, large capacity, and strong scalability.

Q、How to Deploy SFP+ Optical Modules with Switches

A、Different optical modules, when connected to switches, serve various networking schemes. Here are several practical configurations of SFP+ modules with switches.

• Connection between 10G SFP+ 10 Gigabit Optical Modules and Switches

Four 10G SFP+ modules are inserted into a switch’s 10-Gbps SFP+ ports, followed by installing a 40G QSFP+ module into another switch’s 40-Gbps QSFP+ port, with a break-out fiber patch cable linking them in between.

This configuration primarily facilitates the network’s expansion from 10G to 40G, swiftly and effortlessly addressing data center network upgrade demands.

• Connection between BIDI SFP+ 10 Gigabit Bi-Directional Single-Fiber Optical Modules and Switches

By inserting the modules into the SFP+ ports of two switches and connecting them via LC fiber patch cables that match the module interfaces, this approach establishes the simplest and most economical data link. It’s applicable for Ethernet connections in data centers, corporate wiring, and telecom operations transmission.

• Connection between CWDM SFP+ 10 Gigabit Optical Modules and Switches

This setup involves the use of media converters, fiber transceivers, and CWDM multiplexers to connect the modules to switches, effectively converting RJ45 electrical interfaces on 10G Ethernet switches to the CWDM wavelengths necessary for CWDM multiplexing.

• Connection between DWDM SFP+ 10 Gigabit Optical Modules and Switches

Inserted into the SFP+ ports of switches and linked to a DWDM multiplexer with armored fiber patch cables, this method ensures the protection of optical signals during long-haul transmission, minimizing optical wave loss and making it apt for extended distance optical signal transmission.
