GPON OLT SFP Module, C+++ Class 2.5G/1.25G SC/PC Optical Module, 20km

Product Overview

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

This GPON OLT Optical Module supports 2.5G downstream and 1.25G upstream transmission, making it suitable for standard GPON access networks. With a 1490nm transmit wavelength and 1310nm receive wavelength, it is designed for OLT-side GPON communication with ONU and ONT devices across passive optical distribution networks.

As a GPON C+++ SFP Module, it is available with high optical power options including 7dBm+, 8dBm+, 9dBm+, and 10dBm+. These power options help network engineers select the right optical budget according to splitter ratio, fiber link loss, connector loss, and deployment distance.

Luleey provides GPON OLT Transceiver compatibility options for Huawei, ZTE, FiberHome, and other OLT platforms, helping ISPs, system integrators, and FTTH operators deploy or replace GPON OLT modules with better flexibility.

Specifications

Why Choose a GPON OLT SFP Module?

A GPON OLT SFP Module is used on the optical line terminal side of a GPON network. It connects the OLT equipment to the passive optical distribution network and communicates with ONU or ONT devices on the subscriber side.

For ISPs and network operators, the right GPON OLT Optical Module is important because it affects link stability, optical budget, splitter support, and long-distance performance.

The Luleey GPON OLT SFP Module provides a compact SFP form factor, DDM monitoring, 20km transmission distance, and multiple optical power options for different GPON access scenarios.

Optical Power Selection Notes

This GPON C+++ SFP Module is available with several optical power options. Choosing the correct power level depends on the actual network design.

Typical factors include:

• Fiber cable distance
• Optical splitter ratio
• Connector and adapter loss
• Patch cord quality
• ONU/ONT receiver sensitivity
• ODN design margin
• Existing OLT compatibility

For short or low-loss networks, a lower optical power option may be enough. For higher splitter ratios or longer fiber routes, a higher power option may provide more optical budget.

Engineers should avoid selecting optical power only by distance. A GPON network with many splitters and connectors may require more margin than a simple point-to-point fiber route.

DDM Monitoring for GPON OLT Maintenance

DDM, or Digital Diagnostic Monitoring, allows engineers to monitor important module status information during operation.

Useful DDM values may include:

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

For GPON OLT maintenance, DDM helps engineers identify weak optical power, abnormal temperature, aging links, dirty connectors, or fiber path problems before they become serious network failures.

GPON OLT Module Compatibility

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

The Luleey GPON OLT SFP Module can be supplied with compatibility options for Huawei, ZTE, FiberHome, and other OLT brands. Before ordering, engineers should confirm the OLT brand and model to ensure correct module coding and stable recognition.
