10G Laser Diode Agent for Data Centers

10G Laser Diode Agent for Data Centers

Page Content

10G laser diodes, including FP and DFB types, are key components for high-speed fiber optic transceivers in data centers, supporting O-band and CWDM applications at 10Gbps.

Types of 10G Laser Diodes

Fabry-Perot (FP) Laser Diodes

  • Cost-effective solution for single-channel applications.
  • Operate in the O-band (around 1310 nm) for short to medium-reach fiber networks.
  • Do not require optical isolators, simplifying integration.
  • Suitable for general 10Gbps data center links . Distributed Feedback (DFB) Laser Diodes
  • Provide precise wavelength control, ideal for CWDM and multi-channel applications.
  • Available in wavelengths from 1270 nm to 1370 nm, supporting Ethernet, SDH, PON, and access networks .
  • Edge-emitting with Ridge Wave Guide (RWG) structure and Multi-Quantum Well (MQW) active layers for stable performance .
  • Designed for direct modulation up to 10Gbps and uncooled operation .

Key Specifications

  • Data Rate: Up to 10Gbps for both FP and DFB types .
  • Wavelength Range: FP typically around 1310 nm; DFB covers 1270–1370 nm for CWDM applications .
  • Relaxation Oscillation Frequency: Minimum >10 GHz, ensuring high-speed modulation .
  • Packaging: Available as bare dies, TO-can packages, or fiber-coupled modules with thermal management options .
  • Compliance: RoHS, Telcordia GR-468 standards for reliability and environmental compliance .

Supporting Components

  • Photodiodes: High-speed InGaAs PIN photodiodes, such as the PDC-13D10G, complement 10G laser diodes by providing high responsivity at 1310/1550 nm, low capacitance, and low dark current for 10Gbps fiber optic links .

Integration Considerations

  • Proper heatsinking and low-noise current sources are recommended to maintain performance and reliability .
  • For modules with thermoelectric coolers (TEC), appropriate thermal controllers are required.
  • Fiber coupling and packaging technology affect efficiency and stability, especially in high-density data center environments .

Applications in Data Centers

  • Short to medium-reach 10Gbps Ethernet links.
  • CWDM-based multi-channel transceivers.
  • Optical interconnects for PON, SDH, and access networks.
  • High-speed O-band fiber networks within data centers . These 10G laser diode solutions provide the necessary performance, wavelength precision, and reliability for modern data center optical networks, enabling high-speed, low-latency communication across short and medium distances.
