The Cisco CWDM-SFP-1490= transceiver module is a compact, high-performance, hot-pluggable SFP (Small Form-factor Pluggable) transceiver designed for use with fibre optic networks. It supports the Coarse Wavelength Division Multiplexing (CWDM) technology, enabling multiple signals to be carried over a single optical fibre by using different wavelengths. This enhances the infrastructure’s bandwidth without needing extensive fibre cable upgrades. The module is compatible with a wide range of Cisco switches and routers, making it a versatile solution for organisations looking to expand their network capacity.
The transceiver operates specifically at the 1490 nanometre wavelength, which is part of the CWDM channel plan. It supports data rates of up to 1.25Gbps for Gigabit Ethernet and Fibre Channel applications, ensuring reliable and precise performance. Additionally, this module offers a single LC connector for the fibre connection, providing simplicity in fibre management while maintaining the signal's integrity over longer distances.
This SFP transceiver is hot-swappable, meaning it can be replaced or installed without having to power down the system, contributing to better network maintenance and flexibility in operations. It is built to operate over a range of single-mode fibre (SMF), supporting effective transmission over distances that might otherwise require more expensive infrastructure improvements. Furthermore, being fully compliant with MSA (Multi-Source Agreement) standards ensures this module's broad compatibility with Cisco infrastructure and the ability to work with other vendors that adhere to the same standard.
