Overview
Revolutionize your fiber access network with our industrial-grade 10G EPON Symmetrical OLT SFP+ Transceiver. Designed for next-generation FTTx deployments, this high-performance optical module complies fully with IEEE 802.3av standards. It offers a powerful PR40 power budget, enabling long-reach connections and high split ratios (up to 1:128) without the need for external optical amplifiers.
This versatile module is a dual-rate solution, supporting both 10G/10G symmetric (10.3125Gbps) and legacy 1.25G/1.25G (EPON) speeds. By utilizing a high-efficiency EML laser at 1577nm for downstream and a burst-mode APD receiver at 1270nm for upstream, it ensures robust, high-bandwidth delivery for Triple Play services (Data, Voice, Video). It is the ideal upgrade path for ISPs looking to migrate from Gigabit EPON to 10G capacity while maintaining compatibility with existing infrastructure.

Applications
This 10G EPON OLT module is engineered for the central office (CO) side of passive optical networks. It is the core component for delivering ultra-broadband services in Fiber to the Home (FTTH), Fiber to the Building (FTTB), and Fiber to the Curb (FTTC) scenarios. Telecom operators use this module to provide Gigabit-plus internet plans to residential and business subscribers.
Furthermore, its symmetric 10G capability makes it perfect for enterprise connectivity requiring high upload speeds, such as cloud storage synchronization and HD video conferencing. The module’s backward compatibility allows network architects to deploy 10G OLTs today while servicing a mix of 10G and 1G Optical Network Units (ONUs) on the same ODN (Optical Distribution Network).

Advantages
The primary advantage of this PR40 SFP+ OLT module is its superior optical link budget. Unlike standard PR30 modules, the PR40 class offers higher transmit power and receiver sensitivity. This allows operators to use higher split ratios (e.g., 1:64 or 1:128) per PON port, effectively doubling or quadrupling the number of subscribers served by a single OLT card, thereby maximizing ROI.
Additionally, the module’s robust metal housing ensures excellent EMI performance and thermal management. Rigorous testing in real-world traffic environments guarantees that this symmetric 10G transceiver maintains low packet loss and stable latency, even under full load. Whether upgrading an existing network or building a new one, this module provides the reliability required for carrier-grade services.
FAQ (Technical & Product Questions)
1. What does “Symmetric” mean in 10G EPON?
Symmetric means the module supports equal speeds for both downloading and uploading data—10Gbps downstream and 10Gbps upstream. This is crucial for modern enterprise and cloud applications.
2. Can this OLT module support 1G EPON ONUs?
Yes, this is a dual-rate module. It can communicate with both 10G EPON (10G/10G) ONUs and legacy 1G EPON (1.25G/1.25G) ONUs on the same fiber network, depending on the OLT system configuration.
3. What is the difference between PR30 and PR40?
PR30 and PR40 refer to the optical power budget classes. PR40 is a higher power class (>29dB budget), allowing for longer distances or more splitters (more users) on a single fiber compared to PR30.
4. What connector type does this module use?
This module uses a standard SC/UPC simplex receptacle, which is the industry standard for Passive Optical Network (PON) interfaces.
5. Does this module work with Huawei or ZTE OLTs?
Yes, our 10G EPON SFP+ is compatible with major OLT brands like Huawei (MA5800) and ZTE (C300), provided the specific OLT board supports 10G EPON cards.
6. What is the maximum split ratio supported?
With its PR40 power budget, this module typically supports a split ratio of 1:64 or up to 1:128, assuming a standard 20km reach and high-quality optical distribution network components.
7. What wavelengths are used?
For 10G transmission, it uses 1577nm for downstream and receives at 1270nm for upstream. This separation prevents interference with legacy 1G EPON or video overlay signals.
8. Is Digital Optical Monitoring (DOM) supported?
Yes, the module features built-in DDM/DOM functionality, allowing network administrators to monitor critical parameters like optical power, temperature, and voltage in real-time via the OLT interface.
