EPON OLT SFP Module, PX20+++ Class 1.25G SC Optical Module, 20km

Product Overview

The Luleey EPON OLT SFP Module is designed for EPON optical line terminal equipment used in FTTH, FTTB, ISP broadband, campus networks, apartment broadband, and fiber access network deployments. It provides a compact SFP form factor for EPON OLT PON port applications where stable optical transmission, long-distance reach, and device compatibility are required.

This EPON OLT Optical Module supports 1.25G upstream and downstream transmission, making it suitable for standard EPON access networks. With a 1490nm transmit wavelength and 1310nm receive wavelength, it is designed for OLT-side EPON communication with ONU devices across passive optical distribution networks.

As an EPON PX20 SFP Module, it is available with 7dBm+ and 9dBm+ optical power options. These power levels help network engineers select the right optical budget according to splitter ratio, fiber distance, connector loss, patch cord quality, and ODN design margin.

Luleey provides EPON OLT Transceiver compatibility options for Huawei, ZTE, FiberHome, BDCOM, VSOL, HIOSO, TP-Link, and other OLT platforms, helping ISPs, system integrators, and broadband operators deploy or replace EPON OLT modules with better flexibility.

Specifications

Why Choose an EPON OLT SFP Module?

An EPON OLT SFP Module is used on the optical line terminal side of an EPON network. It connects the OLT equipment to the passive optical distribution network and communicates with ONU devices on the subscriber side.

For ISPs and broadband operators, the right EPON OLT Optical Module is important because it affects optical budget, splitter support, link stability, and OLT compatibility.

The Luleey EPON OLT SFP Module provides a compact SFP package, 1.25G EPON transmission, DDM monitoring, 20km transmission distance, and multiple optical power options for different EPON access scenarios.

Optical Power Selection Notes

This EPON PX20 SFP Module is available with 7dBm+ and 9dBm+ optical power options. The correct option depends on the actual network design rather than distance alone.

Important factors include:

• Fiber cable distance
• Optical splitter ratio
• Connector and adapter loss
• Patch cord quality
• ONU receiver sensitivity
• ODN design margin
• Existing OLT compatibility
• Number of passive optical distribution points

For smaller or lower-loss networks, 7dBm+ may be sufficient. For higher splitter ratios, longer routes, or more complex ODN designs, 9dBm+ may provide better optical budget margin.

EPON vs GPON OLT SFP Module

EPON and GPON optical modules are not interchangeable. They use different network standards and are designed for different OLT systems.

Choose the EPON OLT SFP Module when your equipment and access network are based on EPON.

Choose a GPON OLT module when your OLT platform and subscriber devices are GPON-based.

DDM Monitoring for EPON OLT Maintenance

DDM, or Digital Diagnostic Monitoring, helps engineers monitor the operating status of the optical module in real time.

Useful DDM values may include:

• Optical transmit power
• Optical receive power
• Module temperature
• Supply voltage
• Laser bias current

For EPON OLT maintenance, DDM helps identify weak optical power, abnormal temperature, aging links, dirty connectors, or fiber path problems before they cause service interruption.

EPON OLT Module Compatibility

OLT compatibility is one of the most important factors when selecting an EPON OLT Transceiver. Different OLT platforms may require different EEPROM coding or compatibility profiles.

The Luleey EPON OLT SFP Module can be supplied with compatibility options for Huawei, ZTE, FiberHome, BDCOM, VSOL, HIOSO, TP-Link, Ubiquiti, THINK, and other OLT platforms. Before ordering, engineers should confirm the OLT brand and model to ensure correct recognition and stable operation.
