Description
The Sopto SPT-ET4311-SE2CD is a high-performance 1.25Gbps EPON OLT SFP optical transceiver optimized for Ethernet Passive Optical Network (EPON) systems. Operating with 1.25G downstream at 1490 nm and 1.25G upstream at 1310 nm, it delivers reliable optical transmission over single-mode fiber (SMF) for distances up to 20 km, conforming to the 1000BASE-PX20++ specification.
Built with an SC optical interface, the SPT-ET4311-SE2CD provides excellent compatibility and ease of deployment in OLT devices. It features digital diagnostics monitoring (DDM) per SFF-8472 for real-time monitoring of key parameters, including optical power, temperature, and supply voltage.
This transceiver is fully compliant with IEEE 802.3ah EPON, SFP MSA, and RoHS standards, and is ideal for FTTx, ISP access networks, and enterprise PON systems. Compact, hot-pluggable, and commercial temperature rated (0–70°C), it’s designed for reliable long-term operation in network access environments.
