XGS-PON ONU SFP+ Transceiver N1/N2 | 10G Symmetrical | MSA Compliant

Overview

Revolutionize your fiber access network with our high-performance XGS-PON ONU SFP+ Transceiver. Designed for next-generation FTTx deployments, this module serves as a complete Optical Network Unit (ONU) packaged within a compact, industry-standard SFP+ form factor. It enables service providers and enterprise network administrators to deliver symmetrical 10 Gigabit Ethernet speeds for both upstream and downstream traffic, fully adhering to the ITU-T G.9807.1 standard.

In practice, utilizing an XGS-PON SFP+ stick eliminates the need for bulky, standalone ONU boxes (CPE), allowing for a cleaner, more integrated deployment directly into switches, routers, or residential gateways. Available in N1 and N2 classes to suit varying optical link budgets, this transceiver utilizes single-strand fiber technology to provide robust, high-bandwidth connectivity suitable for demanding applications like business broadband, 5G mobile backhaul, and high-density campus networks.

Key Features

• Symmetrical 10G Speed: Supports 9.953 Gbps downstream and 9.953 Gbps upstream data rates.
• Flexible Class Options: Available in N1 and N2 classes to accommodate different optical power budget requirements.
• Integrated ONU Functionality: Functions as a “PON on a Stick,” supporting OMCI management for remote provisioning.
• Standard Interfaces: Features a Simplex SC/UPC connector for optical links and an SFI electrical interface.
• Wavelength Precision: Operates on standard XGS-PON wavelengths (1270nm Tx / 1577nm Rx) to coexist with GPON.
• Advanced Diagnostics: Includes DDM/DOM for real-time monitoring of temperature, voltage, and optical power.

Applications

The XGS-PON ONU SFP+ module is engineered for diverse high-bandwidth scenarios. It is extensively used in Fiber-to-the-Home (FTTH) and Fiber-to-the-Building (FTTB) upgrades where existing GPON infrastructure needs to be modernized to 10G. Additionally, it is a critical component for mobile operators deploying small cells, as it provides low-latency backhaul over passive optical networks. Enterprise users can also plug this module directly into their aggregation switches to establish a 10G wide area network uplink without an external modem.

Specifications

Advantages

Implementing our 10G XGS-PON transceivers offers a significant architectural advantage: simplicity. By integrating the ONU logic into the transceiver itself, network architects can bypass proprietary modem hardware, reducing point-of-failure risks and power consumption. The module is built to rigorous telco-grade standards, ensuring stability even in harsh field environments.

Furthermore, the coexistence capability of this XGS-PON module is a major asset. Because it utilizes 1270nm and 1577nm wavelengths, it can operate on the same fiber plant as legacy GPON services without interference. This allows ISPs to perform a gradual, cost-effective migration to 10G services, upgrading high-value customers to XGS-PON while leaving standard users on GPON infrastructure.

FAQ (Technical & Product Questions)

1. What is the difference between N1 and N2 classes for XGS-PON?

The difference lies in the optical power budget. N1 class transceivers typically support a budget of 14-29 dB, while N2 class transceivers support a higher budget of 16-31 dB. The N2 class offers higher output power and sensitivity, allowing for longer distances or more splitters in the Passive Optical Network (PON).

2. Can I use this XGS-PON ONU SFP+ in a standard 10G switch?

Yes, provided the switch supports SFP+ modules and 10G data rates. This module acts as an “ONU on a Stick,” handling the PON protocol internally. However, you must ensure your switch configuration allows for the specific negotiation required by the module.

3. What wavelengths does this XGS-PON transceiver use?

This module operates on the standard XGS-PON wavelengths defined by ITU-T: it transmits (upstream) at 1270nm and receives (downstream) at 1577nm. This specific separation allows it to coexist with GPON on the same fiber strand.

4. Does this module require a specific OLT to function?

This XGS-PON ONU transceiver complies with ITU-T G.9807.1 standards. While it is designed for interoperability, XGS-PON relies on OMCI management from the OLT (Optical Line Terminal). It is generally compatible with major OLT brands like Huawei, ZTE, and Nokia, but verification of the specific OLT software version is recommended.

5. Is this transceiver compatible with MPO/MTP® cabling?

Typically, PON networks utilize single-strand simplex fiber with SC connectors. While this transceiver has a Simplex SC interface, it can be integrated into broader data center environments that use MPO/MTP® backbones by using appropriate breakout cassettes or fan-out cables to convert the MPO/MTP® trunk into individual simplex SC connections.
