Ubiquiti GPON OLT SFP Module, Class C+

The GPON OLT SFP Module, model UF-GP-C+ from Ubiquiti, represents a pivotal component in the realm of optical network technology, specifically tailored for deployment within gigabit passive optical networks (GPON). As a critical piece of the Ubiquiti Networks® UFiber lineup, this module is designed to be installed in the optical line terminal (OLT) to manage and propagate the high-speed data transmission essential in modern broadband networks. Also, up to 128 UFiber Nano could be connected to one OLT GPON Port.

The UF-GP-C+ module distinguishes itself with a Class C+ rating, which is indicative of its enhanced capability to handle a higher power budget compared to the more common Class B+ modules. This enhancement allows for extended reach and improved performance over greater distances—up to 20 kilometers—thereby facilitating broader network coverage which is especially beneficial in rural or expanded metropolitan deployments where distances between network nodes can be significant.

This module operates with a downstream wavelength of 1490 nm and an upstream wavelength of 1310 nm, typical of GPON technology, ensuring compliance with established GPON standards. It delivers high-speed data transfer rates, achieving downstream speeds of up to 2.488 Gbps and upstream speeds of up to 1.244 Gbps. This asymmetrical data flow is designed to support the heavier downstream traffic generated by end-users in typical internet browsing and media consumption scenarios.

Compliance with the ITU-T G.984.2 standard is a cornerstone of the UF-GP-C+'s design, ensuring interoperability with a wide range of GPON equipment and enabling a flexible, vendor-agnostic approach to network design. This is crucial for service providers looking to integrate the module into diverse and existing network infrastructures without being tied to a single equipment manufacturer.

The inclusion of Digital Diagnostics Monitoring (DDM) in the UF-GP-C+ module allows for real-time monitoring of critical operational parameters such as temperature, voltage, optical power levels, and laser bias current. These diagnostics are vital for maintaining the integrity and efficiency of the network, providing network administrators with the tools needed to preemptively identify and resolve issues before they impact the quality of service.

The small form-factor pluggable (SFP) design of the UF-GP-C+ ensures compatibility with any SFP-equipped OLT device, aligning with industry norms for ease of installation and maintenance. This plug-and-play capability is essential for quick deployment and scalability in dynamic network environments where rapid expansion and adaptability are necessary.
