Realtek Chipsets

HSGMII chipsets are relatively recent, they became more common starting in 2020, and are used in many ONTs. Realtek offers an official SDK, Luna SDK, which offers very good performance in queue management, unfortunately it is not used by all devices based on these chipsets.

The Realtek xPON ICs (RTL9601, RTL9602, RTL9603, RTL9607 and the RTL8290 laser driver) support GPON, EPON and Active Fiber mode, and are distributed in Europe by MEV Elektronik.

The RTL960x family^[1]:

Chipset	Architecture	Type	Notes
RTL9601B	Lexra	SFU	First generation of GPON SFP ONTs, 1G only
RTL9601C1	Lexra	SFU	Second generation of GPON SFP ONTs, 1G and partially 2.5G
RTL9601D	Lexra	SFU/HGU	Third generation of GPON SFP ONTs, stable 2.5G
RTL9602C	Lexra	SFU/HGU	Only in box ONTs
RTL9603C	MIPS	SFU/HGU	All-in-one, 1 core at 900 MHz
RTL9607C	MIPS	SFU/HGU	All-in-one, 2 cores at 1.15 GHz, USB and POTS
RTL9607DQ	ARM64	SFU/HGU	All-in-one, 4 cores at 1 GHz, optional 2.5GbE and POTS
RTL9607F	ARM64	SFU/HGU	All-in-one, 2 cores at 1 GHz, optional USB and POTS

The most common RTL960x based SFP ONTs:

Stick	Chipset	Flash	UNI	4-port emulation	2.5G
V-SOL V2801F	RTL9601CI	8 MB	VEIP & PPTP	✅	modded firmware
T&W TWCGPON657	RTL9601CI	16 MB	VEIP & PPTP	✅ (V2801F fw)	modded firmware
UFiber UF-Instant	RTL9601CI	16 MB	PPTP	❌ LAN 1 only	❌
ODI DFP-34X-2C2 (Realtek)	RTL9601D	8 MB	VEIP & PPTP	✅ SFU firmwares	✅
Nokia G-010S-Q	RTL9601CI	16 MB	PPTP	❌	❌
LEOX LXT-010S-H	RTL9601CI	128 MB			✅

Community guides for the RTL960x based sticks and ONTs (OMCI cloning, flash variables, 4-port emulation, 2.5G compatibility, firmwares and key generators): Hacking RTL960x by Anime4000 and its forum, and the Hacking RTL960x your ISP Fiber fork. The XGS-PON sticks based on the Realtek/Cortina CA8271x are documented in CA8271x.

The useful commands for the Realtek sticks running the Luna SDK are in each device page, e.g. ODI DFP-34X-2C2.

End Of Life

Realtek announced that the RTL9601C and RTL9601CI will be End Of Life at the end of November 2026, and they will not get a replacement.

Lantiq Chipsets

Unfortunately Lantiq no longer exists as it has been bought out and dismembered by Intel. This purchase was a huge deal as at the time Lantiq was at the forefront of the GPON and xDSL chipset market. The GPON part of Lantiq ended up in /dev/null, while the XGS-PON sector ended up in the hands of MaxLinear and the whole Wi-Fi part remained in the hands of Intel itself.

The last produced batches of these SFPs date back to 2020/2021. All OEMs are currently migrating to Realtek.

End Of Life

The Lantiq Falcon GPON chipsets (PEB98010, PEB98035, PEB98036) are End Of Life: the SFPs based on them (Huawei MA5671A, Nokia G-010S-P, FS.com GPON-ONU-34-20BI, CarlitoxxPro/Hilink, ...) are no longer produced and are now hard to find, see the MikroTik forum.

Warning

Playing with ONTs can cause your serial number/PLOAM password to be banned and faults to the optics, ONTs and OLTs. Always pay close attention to the calibration of the laser, under no circumstances should the calibration be changed.
