The VSC8490YJU-14 is an advanced, fully integrated Quad Small Form-Factor Pluggable (QSFP) optical transceiver offering four channels of both transmit and receive capabilities. The VSC8490YJU-14 is designed to operate within a high-speed, 10 Gigabit Ethernet networking application. It provides the user with a low power consumption and a high performance option when connecting data between two or more points.

Features

The VSC8490YJU-14 enables high-speed data communication through an array of advanced features. These include four channels of transmit and receive capabilities, low power consumption, flexible module design, wavelength-dependent transmit power and improved eye-safety. The VSC8490YJU-14 is available in a variety of temperatures from 0°C to 85°C and is RoHS compliant.

Applications

The VSC8490YJU-14 is designed for applications such as 10-Gigabit Ethernet, InfiniBand and Fibre Channel. It provides four channels of transmit and receive to enable high-speed data communication over short distances (< 10 km). The transceiver is also suited to use in extended networks hosting multi-protocol transport or multi-layer switching equipment.

Working Principle

The VSC8490YJU-14 employs a digital-to-optical, dual-stage technology to convert digital data into a light signal. This signal is then passed through a transmitter, which amplifies the signal to the appropriate level. The VSC8490YJU-14 then utilizes a photodiode receiver to convert the light signal back into digital form.

The VSC8490YJU-14 has a transmitter stage which comprises of a Fabry-Perot laser diode. This acts as an optical attenuator and provides wavelength-dependent transmit power to improve eye-safety levels. The receiver stage consists of a photodiode array, which can convert the light signal back into electrical current then into digital data.

Conclusion

The VSC8490YJU-14 is a fully integrated Quad Small Form-Factor Pluggable (QSFP) optical transceiver designed to meet the needs of high-speed, 10 Gigabit Ethernet networks. It features four channels of transmit and receive capabilities, low power consumption, flexible module design and wavelength-dependent transmit power for improved eye-safety. The VSC8490YJU-14 is suitable for use in 10-Gigabit Ethernet, InfiniBand and Fibre Channel networks as well as extended networks hosting multi-protocol transport or multi-layer switching equipment.
