Features
WFL54320A9-KCSP
The GPON OLT SFP Class C++ transceiver is a specialized optical module for GPON systems, compliant with ITU-T G.984.2 standards. Operating at 2.488Gbps downstream and 1.244Gbps upstream, it features a 1490nm DFB transmitter and 1310nm APD receiver over SC/UPC single-mode fiber. Available in Class B+, C+, and C++ power levels with link budgets from 28dB to 33dB, it supports 20km reach and split ratios up to 1:128. With hot-pluggable SFP design, 3.3V supply, and built-in DDM, it delivers reliable performance for FTTx deployments.
The GPON OLT SFP Class C++ transceiver equipped with an LVTTL receiver featuring fast burst packet detect indication, this transceiver instantly recognizes incoming optical bursts for rapid signal acquisition. This high-speed detection capability ensures minimal packet loss and low latency, critical for dynamic GPON upstream traffic where bursts arrive unpredictably from multiple ONUs. Count on reliable, instantaneous burst recognition that keeps your network responsive and your data flowing without interruption.
The GPON OLT SFP Class C++ transceiver includes a built-in burst mode RSSI function that measures incoming optical signal strength in real time. This feature gives your network instant feedback on received power levels, ensuring stable performance even with unpredictable burst traffic. With clear and timely signal data, you can quickly spot link issues and keep your network running smoothly.
Designed to meet strict Class I laser safety requirements under IEC-60825, The GPON OLT SFP Class C++ transceiver is completely safe for everyday use. It poses no risk to eyes or skin under normal operating conditions, making it ideal for offices, data centers, and public networks. Deploy with full confidence knowing that every unit meets international safety standards for worry-free operation.
Built to meet SFP MSA and SFF-8472 standards, this transceiver works smoothly with almost all networking equipment on the market. You can install it into any standards-based switch or router without worrying about compatibility issues or vendor lock-in. Plug it in, and it just works - saving you time and reducing setup headaches.
The GPON OLT SFP Class C++ transceiver meets ITU-T G.984.2 standards with support for Class B+, C+, and C++ power levels, giving you the flexibility to choose the right link budget for your network. This means you can match the transceiver to your specific split ratios and reach requirements without overpaying for unnecessary power. Choose the class that fits your needs, and enjoy reliable, standards-based performance every time.
