Meet the HALNy HLX-SFPX: GPON on a Stick

When you think of fiber connectivity, you might picture a bulky ONU box tucked away in a telecom cabinet. But what if you could shrink that functionality into something smaller, like a thumb drive? Enter the HALNy HLX-SFPX, a cutting-edge XGS-PON stick ONU that plugs directly into an SFP+ port, delivering up to 10 Gbps symmetrical speeds, no extra hardware required.

Hi I’m Juan David and  Flytec’s Tech Support Lead, I love testing products that push the boundaries of network design. And trust me, this one does.

What Is It?

The HLX-SFPX is a full-featured XGS-PON ONU built into an SFP+ form factor. That means you can plug it into compatible routers, switches, or firewalls with SFP+ ports and get instant access to fiber-to-the-home (FTTH) or business-class 10G fiber broadband, without the need for a traditional ONU.

Why It’s a Game-Changer

• Plug-and-Play Form Factor – Integrates directly into customer-premises equipment (CPE) or edge devices with SFP+ slots.
• XGS-PON Power – Supports 953 Gbps downstream and upstream with full compliance to ITU-T G.9807.1 and G.988 standards.
• Wide Compatibility – Interoperates with OLTs from vendors like Nokia, Huawei, ZTE, DASAN, and many more.
• Layer 2 Smart Features – Built-in VLAN translation, QoS, QinQ, and IGMP snooping.
• Secure and Reliable – Includes AES encryption and forward error correction for peace of mind.
• Multiple Speed Support – SFP+ LAN interface supports 10G/2.5G/1G, making it versatile across various deployments.
• Layer 3 Ready – Supports IP Host mode for remote management and provisioning, allowing out-of-band access and streamlined monitoring.

Use Cases

• FTTx deployments—including FTTH, FTTB, and FTTC—requiring ultra-compact ONUs.
• Business customers requiring high-speed symmetric bandwidth.
• ISPs looking to simplify installations and reduce hardware footprint.
• Remote routers/firewalls with an empty SFP+ port—plug this in, and get rid of your modem.

Tech Specs at a Glance

• WAN Port: XGS-PON Class N2 (SC/APC)
• Speed: 9.953 Gbps up/down
• LAN Interface: 10G SFP+ (SFI/SGMII)
• Management: OMCI support with remote provisioning
• Compliant Protocols: IEEE 802.1D/Q/P, QinQ, DHCP, CoS, DSCP

Final Thoughts

If you're looking for a future-proof, plug-and-play ONU that eliminates bulky installations, the HALNy HLX-SFPX is the answer. This compact GPON/XGS-PON stick connects directly to an OLT headend, delivering high-speed internet via 10G PON to any SFP+ port. Its flexibility makes it a perfect fit for residential, business, and MDU deployments alike.
