The module has a config option to be used for forcing at 2500, but still the EEPROM is not reporting the rigth speed and, as far as I know, Linux is not negotiating 2500. on the contrary using the quirk, I do not know why the modle is running at 2500 even if the module is configured for 1000. This is it. I suppose the quirk forces 2500 even if the EEPROM is not reporting the 2500 speed. I do not think it is only for fiber. The quirk is also used tor some copper sfp not running in FIBER MODE.
Hello, need R3 compatible optical module for connection with TP-Link 1Gb WDM SC 1550/1310nm media converter. Can anyone confirm whether these work?
I haven’t tested this specific module but as it is a simple 1000MBit/s optical module chances for it to work just fine are around 99%.

Hi, I have something similar, that report itself as “OEM SFP-GE-T”, doing the loop:
mt7530-mdio mdio-bus:1f sfp2: Link is Up - 1Gbps/Full - flow control off
br-lan: port 5(sfp2) entered blocking state
br-lan: port 5(sfp2) entered forwarding state
mt7530-mdio mdio-bus:1f sfp2: Link is Down
br-lan: port 5(sfp2) entered disabled state
mt7530-mdio mdio-bus:1f sfp2: Link is Up - 1Gbps/Full - flow control off
any thought how it can be fixed?
upd: looks like on BPI R4 something similar works FYI: This $10 1000Base-T SFP Transceiver works with the BPi-R4
upd2: looks like there is patch already done by @dangowrt https://patchwork.kernel.org/project/netdevbpf/patch/[email protected]/
I i understand correctly it will be integrated into next OpenWRT stable release
For my BPI-R3 I now gave H!Fiber ASF-GE-T-Cisco-2pcs-HF(EU) a try.
But unfortunately with no success.
I run 6.12-main (and also tried others) from Franks Repo BPI-Router-Linux. Thanks for providing this.
Both SFPs RJ45 (originally named lan4 and eth1) are connected to a Gbit/s Switch to test 1000BASE-T.
After
ifup lan4
or
ifup eth1
respectively the Gbit/s Switch LEDs light up and indicate a link.
But the logging says:

In ‘drivers/net/phy/sfp.c’ I see
// OEM SFP-GE-T is a 1000Base-T module with broken TX_FAULT indicator
SFP_QUIRK_F("OEM", "SFP-GE-T", sfp_fixup_ignore_tx_fault),
exists.
Is there a known way (special kernel version, patches etc.) to get SFP-GE-T working with 1000BASE-T?
Are there other brand SFPs around with better support for 1000BASE-T to work in a BPI-R3?
For the h!fibre i needed no quirk/fixup,it worked out-of-the-box…seems there is something broken now.
Seems your mac is forced to 2500-base…and not allowong the 1g mode
ok, but as I’ve seen you use an optical medium (no copper as I do). Maybe this has an impact too on the issue.
What kernel version/patches do you use? I could give this a try…
Ah,right,i use optical one,possibly that eeprom differs
after the big disappointment with cheap H!Fiber ASF-GE-T-Cisco-2pcs-HF(EU) SFPs I have now tested with (not so cheap):
10Gtek ASF-2G2-T+(OEM-EU)
What can i say? It’s awesome!
The first 1000BASE-T Copper RJ45 SFP Transceiver I know of that just works in a BPI-R3 
On Debian + Kernel e.g. 6.12.0-bpi-r3-main.
I can tell you what’s broken:
You forgot to include
<M> Marvell Alaska PHYs
<M> Marvell Alaska 10Gbit PHYs
<M> Marvell 88Q2XXX PHY
<M> Marvell 88X2222 PHY
drivers in your .config. After doing that now even H!Fiber ASF-GE-T-Cisco-2pcs-HF(EU) SFPs work with 1000BASE-T Copper RJ45
thanks to @bruzzin for hinting me the missing drivers
Ok,when the sfp has a phy (seems often for copper sfp,but unlikely for fibre) a driver is maybe needed.
ok, you could consider to include SFP related phy drivers in your build since it is essential for a BPI-R3 based “router”. The overhead to build such additional modules is minimal…
Which one do you need? I try to keep the defconfig as small as possible to reduce compile time (also for pipeline).
Thinking about an additional options for full builds which are appended to the minimal defconfig,but had no good idea how to do it exactly.

to support H!Fiber ASF-GE-T-Cisco-2pcs-HF(EU) with 1000BASE-T Copper RJ45 it’s sufficient to set
CONFIG_MARVELL_PHY=m

Added to r3/r4 defconfigs
and added function+files to 6.13-rc to append defconfig

It works with Openwrt 24.10. Thanks for fixing, now we have dirt cheap (mine was 2usd on promotion) Ethernet modules. upd: (context BPI-R3 SFP Module compatibility - #121 by bademux)
What was fixed? Did I miss something?
Afaik kmod-phy-marvell has always been there, one only needs to install that module to have support for 1G copper SFP with Marvell PHY…
Since i upgraded to Openwrt 24.10 now my SFP transceiver randomly disconnect

I have to unplug it from the transceiver and plug it into an RJ45 port to regain network access. It’s not a cable problem, i’m using a brand new one cat 7.
Sometimes it works for 15 minutes and then it starts disconecting. i never had this problem before, with the previous versions of openwrt.
My module is only working at 2.5Gbps, it doesn’t support 1Gbps.
