As we know, CWDM (Coarse Wavelength Division Multiplexing) is a technology of combining multiple signals on laser beams at various wavelengths for transmission along fiber optic cable. It is a choice for cost efficiently transporting large amounts of data traffic in telecoms or enterprise networks. By using CWDM technology, different transceivers can have different wavelengths assigned to them. These SFPs designed with CWDM technology we called CWDM SFPs. CWDM SFP module is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fiber Channel(FC) in campus, data-center, and metropolitan-area access networks. This paper will take an overview of Cisco CWDM SFPs, and share a cost-effective and scalable solution to it.
Cisco CWDM Modules Brief Introduction
According to the definition of Cisco System, a Cisco Coarse Wavelength Divison Multiplexing (CWDM) SFP is a hot-swappable input/output device that plugs into an SFP port or slot of a Cisco switch or router, and links the port with the fiber-optic network. The Cisco CWDM SFPs are multirate parts that support both Gigabit Ethernet and Fibre Channel (1 Gigabit and 2 Gigabit). They come in eight wavelengths that range from 1470 nm to 1610nm. In addition, in order to better identify the wavelength to which the Gigabit Ethernet channel is mapped when using these CWDM SFPs, Cisco use the color markings on the devices (Color arrow on label & Color coded bale clasp) to achieve this. The following table lists the Cisco CWDM SFPs with their wavelength and color codes as well as the Cisco CWDM SFPs supported platform and minimun software release requirements.
