The GPON ONU SFP Transceiver is designed for Gigabit-capable Passive Optical Network（GPON）transmission. The module incorporates 1310nm burst-mode transmitter and 1490nm continuous-mode receiver. The transmitter section uses a 1310nm DFB laser and an integrated BM laser driver which designed to perform very small burst enable/disable delay time. The laser driver also includes digital APC and temperature compensation circuit, which are used for keeping the launch optical power and extinction ratio constantover temperature and aging. The receiver section uses an integrated 1490nm APD photodiode and preamplifier mounted together. It has the function that indicates receiver signal-detected status (active high). An integrated WDM coupler can separate 1490nm input light and 1310nm output light. The metallic package guarantees excellent EMI and EMC characteristics, which totally comply with international relevant standards.
Features
Optical transceiver for Gigabit-capable Passive Optical Networks (GPON) ONU side: This transceiver is specifically designed for use on the Optical Network Unit (ONU) side of Gigabit-capable Passive Optical Networks (GPON). It enables high-speed data transmission and reception over optical fibers.
Integrated Single-fiber bi-directional optical subassembly: The transceiver incorporates a single-fiber bi-directional optical subassembly, which allows for both transmission and reception of optical signals over a single fiber, simplifying network architecture and reducing costs.
SFP Package with SC Receptacle: The transceiver is packaged in a standard SFP (Small Form-factor Pluggable) module, with an SC receptacle for easy installation and interconnection with optical fibers.
1310nm DFB laser Burst-mode Transmitter and 1490nm APD Continuous receiver (with WDM): The module utilizes a 1310nm Distributed Feedback (DFB) laser in burst-mode for transmission and a 1490nm Avalanche Photodiode (APD) for continuous reception. The integration of Wavelength Division Multiplexing (WDM) technology allows for simultaneous transmission and reception over the same fiber.
+3.3V single power supply: The transceiver operates on a single +3.3V power supply, simplifying power management and reducing the overall power consumption of the system.
