Description
The BD-4321S-C2CDA is a top-tier SFP OLT (Optical Line Terminal) transceiver designed for single-fiber networks, featuring a 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. This high-performance transceiver supports ITU-T G984.2 standards, offering stable and reliable data transmission for up to 20km. The BD-4321S-C2CDA is built with advanced features such as automatic power control (APC), temperature compensation circuitry, and a burst-mode receiver for fast response times. The module operates on a single 3.3V power supply, ensuring energy efficiency. With compliance to industry standards like RoHS and IEC825, this transceiver guarantees reliable operation in various network environments, ideal for fiber-optic communication solutions.
GPON SFP OLT Transceiver Features:
- Single Fiber Design: Utilizes single-mode fiber with an SC receptacle for easy installation and superior performance.
- 1490nm Continuous-Mode Transmitter: Incorporates a DFB laser with APC function and temperature compensation for stable operation across varying temperatures.
- 1310nm Burst-Mode Receiver: Features a hermetically packaged APD-TIA with a burst-mode limiting amplifier and LVPECL-compatible outputs for fast and accurate data transmission.
- Long-Distance Transmission: Capable of supporting up to 20km transmission, ideal for long-range applications.
- Advanced Burst-Mode Functionality: Includes burst mode signal detect output (LVTTL compatible) and fast RSSI (Received Signal Strength Indication) output, enabling efficient monitoring of ONU power.
- Power Efficiency: Operates with a single 3.3V power supply, reducing power consumption.
- Digital Diagnostic Interface: Complies with SFF-8472 Rev 9.4 for real-time monitoring and system diagnostics.
- Standards Compliance: Fully compliant with ITU-T G984.2 Class C+ and RoHS directive (2002/95/EC), ensuring quality and environmental safety.
- Wide Temperature Range: Operates reliably in standard temperatures from 0°C to +70°C, providing flexibility for various deployment environments.
