Optical Communication LEDs — Advanced LED Solutions for Industrial Applications

Application Overview

QUEENDOM’s Optical Communication LED portfolio addresses the growing demand for cost-effective optical data transmission in short-reach applications where laser diodes are economically impractical. The 850nm vertical-cavity surface-emitting LEDs (VCSELs) support multi-mode fiber transmission at 1-25 Gbps for data center interconnects and automotive MOST (Media Oriented Systems Transport) networks. The 1310nm edge-emitting devices enable single-mode fiber links up to 10km for industrial Ethernet and telecommunications access networks. For emerging Li-Fi (Light Fidelity) applications, our high-speed white LEDs with integrated blue GaN chips and phosphor modulation bandwidths exceeding 500MHz support bidirectional visible light communication at 100+ Mbps. The critical specifications for optical communication include: rise/fall times <100ps, spectral width <30nm (for 850nm) or <50nm (for 1310nm) to minimize chromatic dispersion, and temperature stability of center wavelength <0.1nm/°C to maintain channel alignment across operating environments. Our TO-46 and TO-56 hermetic packages with integrated thermoelectric coolers (TEC) maintain junction temperatures within ±0.5°C for wavelength-division multiplexing (WDM) applications. The integrated monitor photodiodes enable closed-loop power control that maintains ±0.5dB output stability across -40°C to +85°C temperature range and 15-year operational life. Technical Specifications • Wavelength Range: Application-specific (see product datasheet) • Optical Power: 1mW to 15W depending on configuration • Package Options: 0603, 0805, 2835, 3535, 5050, 7070 ceramic • Operating Temperature: -40°C to +85°C (industrial grade) • Viewing Angle: 30° to 180° (lens and package dependent) • ESD Protection: HBM 2000V-8000V • Lifespan (L70): > 50,000 hours at rated current

Application Cases

Data Center 25G SR Interconnect

A hyperscale cloud provider deployed our 850nm VCSEL arrays in 25GBASE-SR transceivers for intra-rack connectivity. The 25Gbps modulation with <70ps rise/fall times achieved BER <10^-12 over 100m OM4 fiber. The integrated TOSA (Transmitter Optical Sub-Assembly) with monitor photodiode maintained ±0.3dBm output stability across 15-45°C ambient. The 1.2W power consumption was 40% lower than equivalent FP laser solutions. The hermetic TO-56 package achieved Telcordia GR-468 qualification with projected 20-year lifetime. Deployment exceeded 500,000 transceivers with <0.1% field failure rate. Industrial Li-Fi Network A German automotive manufacturer implemented our high-speed white LEDs in a Li-Fi network for electromagnetic-sensitive robot welding cells where Wi-Fi interference caused control errors. The 120Mbps bidirectional communication used intensity modulation of white LEDs at 500MHz bandwidth. The optical link was immune to the 15kA welding current electromagnetic pulses that had disrupted RF systems. The integrated lighting function eliminated separate communication infrastructure. Network latency remained <2ms, meeting real-time robot control requirements. The system operated reliably for 3 years with zero communication failures.
