Knowledge Base Common Application Scenarios of SFP+ Interface
Hi All,
Great news! With the launch of the new Wi-Fi 7 products BE800, BE900 or Deco BE85, our home router products now support the high-speed SFP+ interface. This new interface allows for even faster and more reliable internet connections, providing an enhanced browsing and streaming experience for users.
Introduction of SFP+ Port
The SFP+ port is a high-speed optical-to-optical signal conversion port, mainly used for 10G Ethernet and Fiber Channel network applications. It offers several advantages, including hot-swappability, support for multiple transmission media and protocols, as well as flexibility and scalability.
To establish connections and facilitate data transmission between different devices, the SFP+ port requires the use of either an SFP+ optical module or an SFP+ electrical port module. This ensures seamless compatibility and efficient data transmission across a wide range of devices.
Common Scenarios of using SFP+ Port on Routers
There are several common scenarios for using SFP+ ports on routers:
Scenario 1
High-Speed WAN Connectivity: Leveraging SFP+ Ports for Direct Fiber Optic Connection and High-Speed Internet Access
First, using as a WAN port, with a high-speed SFP+ ONU Stick, it directly replaces the optical modem and connects to the optical fiber network of the ISP to obtain a high-speed network, avoiding the limitation that the optical modem's Ethernet port is usually a Gigabit Ethernet.
a. For the safest replacement method, please contact the ISP directly to ask them to provide an officially verified SFP+ ONU Stick that can be used to replace the optical modem. Generally speaking, if it is an SFP+ ONU Stick directly provided by the ISP, we can connect it to the SFP+ interface of BE800/BE900 so that the router can replace the optical modem to independently complete the dial-up Internet access. Please also remember to switch the SFP+ interface to the WAN port on the router web page.
b. If you decide to purchase the SFP+ ONU Stick and replace the optical modem on your own, please note that we cannot guarantee its compatibility with your ISP's network and its ability to establish an internet connection. ISPs often impose verification restrictions on the optical module or optical modem equipment used with their fiber network.
To ensure uninterrupted internet access and compatibility, we recommend contacting your ISP and verifying the suitable SFP+ ONU Stick and any required verification information for your specific ISP and line.
Original topology with Fiber modem:
ISP Fiber=====>Fiber modem<==Ethernet cable==>(Ethernet WAN)BE800
New topology with SFP+ ONU stick(PON stick):
ISP Fiber===>(PON stick)BE800
PON stick is like this(PON stick is a miniature Fiber modem):
Scenario 2
Ethernet Conversion: Utilizing SFP+ Electrical Port Modules for WAN Connectivity with Ethernet Modems
Second, as a WAN port, you can also use the SFP+ electrical port module to convert to an Ethernet connection and connect to the Ethernet port of the modem through a network cable to achieve high-speed Internet access. In this case, our BE800/BE900 can omit the SFP+ electrical port module and directly use our Combo 10G Ethernet ports or other non-Combo 10G Ethernet ports.
Topology is like this:
ISP Fiber=====>Fiber modem<==Ethernet cable==>(RJ45 SPF+ Module)BE800
RJ45 SFP+ Module is like this:
Scenario 3
High-Speed LAN Communication: Enhancing Local Area Networks with SFP+ Optical and Electrical Port Modules for Fast LAN Communication
Third, as a LAN port, we can also use SFP+ optical modules and SFP+ electrical port modules to connect internal network devices, such as corresponding optical/electrical high-speed switches, servers, high-performance personal PCs and storage devices (such as NAS), etc., to achieve High-speed LAN communication.
Topology is like this:
BE800（Fiber SFP+ Module）<===Optical fiber===>(Fiber SFP+ Module)Switch
Fiber SFP+ Module is like this:
Scenario 4
Ethernet Backhaul EasyMesh Network: Creating a High-Speed Ethernet Backhaul Network by Connecting Multiple EasyMesh Routers through SFP+ Ports
Finally, as a LAN port, after BE800 and BE900 update to support EasyMesh Ethernet Backhaul, we can connect multiple BE800/BE900 through SFP+ ports to form a high-speed Ethernet Backhaul EasyMesh network.
Topology is like this:
BE800（Fiber SFP+ Module）<===Optical fiber===>(Fiber SFP+ Module)BE800
Fiber SFP+ Module is like this:
QA
Q1: Does Fiber SFP+ Module like TL-SM5110-SR can work with Fiber line from ISP?
A: NO. The Fiber interface and Fiber type are different. Fiber lines from ISP can only connect to the Fiber modem or Fiber PON stick.
Fiber SFP+ Module like TL-SM5110-SR should be used in pairs and It doesn't have the modem function.
Q2: Does SFP+ DAC Module can work with Archer BE800/900 and AXE300?
A: NO. We cannot make sure how the DAC cable works with the Archer BE800/900 and AXE300.
It's mainly recommended to use the Optical SFP+ module or AOC cable.
