XG-PON ONU SFP+ Transceiver | 10G/2.5G Asymmetric | N1/N2a | G.987.2

Overview

The XG-PON ONU SFP+ Transceiver is a high-efficiency optical module designed to integrate 10-Gigabit Passive Optical Network (XG-PON) connectivity directly into standard enterprise networking equipment. Known as a “PON on a Stick,” this MSA-compliant SFP+ module contains a complete GPON/XG-PON protocol stack, allowing switches, routers, and firewalls to function as Optical Network Units (ONUs) without requiring external modems or power supplies.

Operating under the ITU-T G.987.2 standard, this transceiver delivers asymmetric bandwidth featuring 9.953 Gbps downstream and 2.488 Gbps upstream. It is the ideal solution for Fiber-to-the-Desk (FTTD), enterprise LAN upgrades, and multi-dwelling unit (MDU) backhaul, offering a seamless migration path from legacy GPON to high-speed 10G services.

Key Features

• Asymmetric XG-PON Rates: Optimized for high-download applications with 10G Down / 2.5G Up.
• SFP+ Form Factor: Hot-pluggable design fits into standard SFP+ ports on routers and switches.
• Optical Class N1/N2a: Robust optical power budget supports split ratios up to 1:128 (dependent on ODN).
• Commercial Temperature Range: Reliable operation from 0°C to 70°C for indoor and data center environments.
• Connector Interface: Single Fiber Simplex SC/UPC (Tx 1270nm / Rx 1577nm).
• Advanced QoS: Supports traffic prioritization and dynamic bandwidth allocation via OMCI.

Applications

• Enterprise Connectivity: Direct fiber connection for high-performance office switches and aggregation routers.
• Campus Networks: High-bandwidth backhaul for universities, hospitals, and corporate campuses.
• Hospitality & MDU: Delivering 10G broadband to hotels or apartment complexes via existing fiber infrastructure.
• Wireless Backhaul: Connecting indoor Wi-Fi 6/6E access points to the core network.

Specifications

Advantages

This XG-PON stick dramatically simplifies network architecture. By replacing bulky standalone ONUs, power adapters, and patch cables with a single plug-in module, network administrators reduce points of failure and clutter. It offers significant CAPEX and OPEX savings by leveraging existing SFP+ ports on current hardware.

Furthermore, the module’s N1/N2a optical class ensures it can communicate effectively over long distances (up to 20km) and through complex splitter hierarchies, making it a versatile choice for diverse network topologies.

FAQ (Technical & Product Questions)

1. What is the difference between XG-PON and XGS-PON?

XG-PON (this module) provides asymmetric speeds: 10Gbps download and 2.5Gbps upload. XGS-PON provides symmetric speeds: 10Gbps for both download and upload. XG-PON is often more cost-effective for residential or general enterprise use where download traffic significantly outweighs upload traffic.

2. Can I use this module to replace a standard GPON stick?

You can physically plug it in, but it will only work if your ISP’s OLT (headend) supports XG-PON. XG-PON operates on different wavelengths (1270nm/1577nm) than GPON (1310nm/1490nm). However, because the wavelengths don’t overlap, XG-PON and GPON can coexist on the same fiber if the OLT uses a coexistence element (CEx).

3. Does this transceiver utilize MPO/MTP® cabling?

No, this module uses a Simplex SC/UPC interface for single-mode fiber. MPO/MTP® connectors are typically high-density multi-fiber connectors used in data center backbones (like 40G/100G SR4), whereas PON technology relies on single-fiber bidirectional transmission.

4. Will this work in any SFP+ switch port?

Generally, yes. The module presents itself as a standard 10G Ethernet interface to the switch. However, some switch manufacturers lock their ports to proprietary codes. Ensure your equipment supports third-party or “open” optics.

5. How do I configure the ONU settings?

Primary configuration (VLANs, bandwidth profiles) is handled remotely by the OLT via the OMCI protocol. Local configuration (like setting the PLOAM password or SLID) is usually done via a web interface accessible through the module’s internal IP address or via SSH.
