GPON ONU SFP Transceiver

Perfectly Designed for FTTx Applications

PLANET GPN-SFP is an SFP GPON ONU device designed in compliance with the ITU-T G.984 standard. It is a cost-effective GPON customer premises system that provides broadband services with 1244 Mbps upstream and 2488 Mbps downstream by connecting to subscribers’ switches or routers. The device complies with G.984.x (1/2/3/4/5) standards and features SFP packaging while integrating a bidirectional optical transceiver and a GPON media access control (MAC) layer function. It delivers Gigabit Ethernet (GigE) service to any device capable of hosting an SFP module, such as Ethernet switches, wireless backhaul equipment, Ethernet access devices (EADs), routers, remote digital subscriber line access modules (DSLAMs), and other customer premises equipment (CPE).

Excellent Access Capacity

GPON supports a PON transmission rate of 2.5 Gbps downstream and 1.25 Gbps upstream. When connected to OLTs, it supports a 1:128 splitting ratio. The network coverage radius can reach up to 20 km.

Compact and Easy-to-Install ONU Stick for SFP Slots

The GPN-SFP is a device that integrates the functions of a traditional Optical Network Terminal (ONT) or Optical Network Unit (ONU) into a compact Small Form-Factor Pluggable (SFP) module. It is designed to be inserted directly into the SFP slot of a switch, router, or industrial device, enabling Passive Optical Network (PON) access.

Secure Service Carrying Capability

To ensure the secure service carrying capability of the ONU, PLANET has developed various technologies, including VLAN, STP, port isolation, ACL, QoS and security filtering.

High-Service Control Capability

PLANET GPN-SFP supports DBA and rate limiting. It also features advanced dynamic bandwidth allocation and precise bandwidth control, enabling users to efficiently share 2.5 Gbps (GPON) and 1.25 Gbps (EPON) bandwidth resources. In addition, the QoS function ensures reliable service quality and prioritization.

Rich OMCI Functions

PLANET GPN-SFP supports the standard OMCI defined by ITU-T, as well as standard OAM and extended OAM defined by Telecom CTC 2.1/3.0, including configuration, alarm management, performance monitoring, fault isolation, and security management. Additionally, it supports private OMCI and OAM defined by PLANET.

Comprehensive Interoperability

PLANET GPN-SFP complies with international standards, including ITU-T G.984.x (1/2/3/4/5), ITU-T G.988, IEEE 802.3ah, PRC Communication Industry Standard GB/T 33845-2017, YD/T 1475-2006, and China Telecom GPON Technical Requirement (CTC). With high interoperability and operability, PLANET GPN-SFP can seamlessly interconnect with OLTs from mainstream manufacturers in the industry, minimizing network construction costs.

Passive Optical Network Connection Solution

With the increasing adoption of network services such as HDTV, IPTV, Voice over IP (VoIP), and multimedia broadband applications, the demand for broadband communication has grown rapidly. PLANET GPN-SFP is one of the most promising next-generation networking (NGN) technologies to meet these needs. Compared to other broadband access technologies such as xDSL and cable modems, PON technology offers several competitive advantages, including the long-term viability of fiber infrastructure, lower operating costs due to the reduction of active components, support for long-distance connections of up to 20 km between equipment nodes, and, most importantly, significantly greater bandwidth.
