Cisco Coarse Wave Division Multiplexing (CWDM) solution has made scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services possible in their networks. This solution mainly combines several different CWDM SFPs (small form-factor pluggable) and a set of CWDM passive multiplexers/demultiplexers or OADMs (optical add-drop multiplexers) to enable flexible network services. This kind of solution is a convenient and cost-effective one.

Before we gain a better understanding of CWDM SFP solution, we can have a look at CWDM SFPs first, an important component in this solution.

A CWDM SFP is a small form factor pluggable module for bi-directional serial optical data communications, and used as a part of CWDM optical network to provide high-capacity bandwidth across an optical fiber network. It is a hot-swappable transceiver component that is used to connect fiber cables and switches. It is designed for single-mode fibers and operates at a nominal wavelength of CWDM wavelength. The image below shows the outlook of CWDM SFP.

Now, let’s return to point CWDM SFP solution. The following passages mainly discuss three advantages of Cisco CWDM SFP solution.

Cisco CWDM solution is scalable, meaning that multiple channels can be provided as data demands increase. The scalability of CWDM SFP solution enables the transmission of up to eight channels over single-mode fibers. Besides, CWDM SFP transceivers are hot-swappable and they can be easily installed. What’s more, the devices contained in CWDM SFP solution are passive and require no power. Various network configurations ranging from multi-channel point-to-point to hub and meshed-ring configurations make this scalable CWDM SFP solution desirable for designers in telecommunication industry.

The components of Cisco CWDM SFP solution offer in Fiberstore are reliable and become a preferred choice for designers to avoid deployment failure incurred by other devices with low quality, thus saving money. In addition, while allowing enterprises and service providers to increase the bandwidth of an existing Gigabit Ethernet optical infrastructure, CWDM SFP solution doesn’t need to add any additional fibers. This solution can also be used in conjunction with other Cisco SFP devices on the same platform. In this way, investment can be protected.

Cisco CWDM SFP solution takes advantage of a multi-channel architecture and the inherent protection of ring architectures. At the channel endpoints, layer redundancy and failover mechanisms are used to allow designers to build highly available links. Additionally, in a ring architecture, the two-path link configurations are used to provide protection from fiber cuts.

Cisco CWDM SFP solution offers functionality in increasing network capacities and data transmission speed. Fiberstore, as a third party, offers CWDM SFP solution components, like CWDM multiplexers/demultiplexers, OADM, and CWDM SFPs. Besides CWDM SFPs, other Cisco compatible SFPs are also supplied, such as Cisco GLC-SX-MM and Cisco GLC-SX-MMD. You can see GLC-SX-MM price at Fiberstore.
