| 10 Gbps VCSEL Product Description The 10Gbps VCSEL is a high-performance, near-infrared, 850nm VCSEL (Vertical Cavity Surface-Emitting Laser) tailored to meet the needs of high-speed data communications and telecommunications applications. The product is offered in die form only with two top side contacts for easy integration into a wide variety of low-cost, high-performance packages for OEM use in Gigabit Ethernet, Fibre Channel, and ATM transceiver modules and systems. Application The 10Gbps VCSEL is designed to convert electrical current into optical power that can be used in fiber optic communication systems and other applications. The device operates in multiple transverse and single longitudinal modes, ensuring stable coupling of power and low noise when used with multimode fiber.
