Description
The Sopto SPT-GT4321-SC2CD is a high-performance GPON OLT SFP transceiver engineered for Gigabit Passive Optical Network (GPON) applications. It delivers 2.5 Gbps downstream at 1490 nm and 1.25 Gbps upstream at 1310 nm over single-mode fiber (SMF), enabling reliable fiber access up to 20 km depending on system configuration.
Compliant with ITU-T G.984.2, SFP MSA, and RoHS standards, this module integrates digital diagnostics monitoring (DDM) per SFF-8472 for real-time monitoring of temperature, voltage, and optical power. The Class C++ optical budget (up to 32 dB) provides superior link stability and longer reach for dense FTTx deployments.
With its SC optical interface, hot-pluggable SFP form factor, and low power consumption, the SPT-GT4321-SC2CD ensures easy integration and maintenance in OLT devices. The commercial-temperature rating (0 °C ~ +70 °C) and EMI-shielded metal housing make it a durable, high-efficiency solution for GPON OLT systems, ISP access, and enterprise FTTx networks.
