Summary
This study integrates multiple-lane links into an L-band Vertical Cavity Surface Emitting Laser (VCSEL)-based Wavelength Division Multiplexing (WDM) system. Successful 10 km data transmission was achieved at 4x14Gbps with minimal penalties.
Area of Science:
- Optoelectronics and Communications
Background:
- Wavelength Division Multiplexing (WDM) systems are crucial for high-capacity optical communication.
- Vertical Cavity Surface Emitting Lasers (VCSELs) offer a cost-effective solution for optical transceivers.
Purpose of the Study:
- To investigate the feasibility of migrating multiple-lane links into an L-band VCSEL-based WDM system.
- To evaluate the performance of such a system for data transmission.
Main Methods:
- Implementation of a WDM system utilizing L-band VCSELs.
- Integration of multiple-lane links within the WDM architecture.
- Experimental transmission of data over 10 km of single-mode fiber (SMF).
Main Results:
- Successful data transmission achieved at a rate of 4x14Gbps over 10 km SMF.
- Inter-channel crosstalk penalty was measured to be less than 0.5 dB.
- Overall transmission penalty was approximately 1 dB, with a power budget margin of 6-7 dB.
Conclusions:
- The L-band VCSEL-based WDM system with multiple-lane links demonstrates robust performance.
- The system is suitable for high-speed data transmission applications over standard optical fiber infrastructure.
- Minimal crosstalk and sufficient power budget indicate the viability of this approach for future optical networks.
