Tags: #Network Connectivity #10 Gbps #SFP+ #VR
Model: Archer BE800  
Hardware Version: V1
Firmware Version: 1.2.3 Build 20250314 rel 45415

I run the following for among other things a streaming VR setup

 

PC
├─ Intel i9-14900 96GB

├─ Windows 11
├─ NVIDIA RTX 4090
└─ TP-Link TX401 (10GBase-T, AQC107)

↔ 3m Cat7

TP-Link BE800 (Router/Switch 1)
↔ 15m Cat7 (10GBase-T)

TP-Link BE800 (Router/Switch 2 - Internet gateway)
↔ Wi-Fi 7 (6GHz)

Pico 4 Ultra (VR headset)

 

In the constant OCD drive to tweak and get a little  less latency  i'd like to try replacing the copper connections and PC NIC with Fibre .

 

ChatGPT says this about the BE800

 

The Problem with TP-Link BE800 + SFP+

  • SFP+ auto-negotiation is not standardized the same way as RJ45 (NBASE-T), so:

    • Modules and cables must match exactly in spec and compatibility.

    • The BE800's SFP+ ports may not support 5G/10G Base-R properly.

  • TP-Link firmware often lacks advanced diagnostics or DDM (Digital Diagnostic Monitoring) for SFP+, making troubleshooting a black box.

  • Many users report that BE800 SFP+ ports fall back to 1G/2.5G only unless using TP-Link’s own modules, which are hard to source or undocumented.

 

I purchased an SFP+ cable from a local shopping site and as described above it would never go faster that 1G.

I recognize that vendor lawyers hate the term supported because they think we all will sue. However i'd be interested to know if anyone has any vendors or specifications of any SFP devices that can be generally purchased on the open market and are known to work with the BE800 SFP+ ports  at 10Gbe. Regardless of what you think of my quest I think this list would useful to others who may want to look at SFP in the future.  

 

I need an SFP+ PCIE NIC and two fibre connections.

Hi@StFual,

Thank you for contacting our community.

 

Is your network topology diagram as follows: ISP modem—main router—satellite router )))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

 

SFP+ ports are typically found on high-end networking equipment such as Archer AXE300 and WiFi 7 Routers Archer BE800 etc., which can be used for LAN or WAN connection in the four common application scenarios: Common Application Scenarios of SFP+ Interface

Which of the above situations do you need?

 

There are quite a few SFP+ modules that are compatible with 10Gbps, and some users have reported that other non-TP-Link modules can operate normally at 10Gbps speed. May I know what is the model of your SFP+ module?

The two configurations i am considering and would like a working solution for..

BE800（Fiber SFP+ Module）<===Optical fiber===>(Fiber SFP+ Module)BE800
Currently running 15M 10Gbe

 

BE800（Fiber SFP+ Module）<===Optical fiber===>(Fiber SFP+ Module) SFP+ PC Interface card
Currently running  2M 10Ggbe to a TX401 Tplink card.

 

My SFP+ cable is generic chinese brand.

Levered the covers off the fibre cable. Chips inside are 

1: P24C08C-3L2TB2   EEPROM
2: GN1196-5501E3-2337  Lazer driver  12.5Gbps 

 

Happily purchase a TpLink SFP+ fibre  if you can actually sell it through your distributors - or anybrand  SFP+ cable your distrbution channels are willing to support  works at at 10G.

 

To those that say you dont need it. 

Not sure why i should need to justify  why I want to use a feature that is marketed and installed in a device I purchased, and a feature  that added significantly to the cost of the devices purchased but here we go anyway.

My understanding is because of electrical noise and higher frequencies 10Gbe has a much higher error correction overhead than SFP+ giving slightly lower data throughput and  higher latency.  I have more than enough data throughput but in a VR environment any improvements I can make in latency i'll take.   

I want to test with 10G SFP+   and if it is better make use of it.
