What Are the Application Cases of 10G CWDM SFP+?

Posted on Dec 22, 2023 by

Due to the ease of development and cost-effectiveness, 10G CWDM networks have been applied in various fields though they offer less data capacity than DWDM networks. 10G CWDM SFP+ modules can transmit multiple protocols at specific wavelengths such as passive network technology. The article will examine examples of 10G CWDM SFP+ network applications in different sectors.

Advantages of 10G CWDM SFP+ Solution

Below are the main advantages of 10G CWDM SFP+ solutions:

  • CWDM Mux/Demux provides a cost-effective and power-free solution for network design.

  • 10G networks can be easily upgraded to 40G or 100G, supporting increased connections and channel expansion.

  • The cost of 10G network equipment is low, and components like 8-channel CWDM Mux/Demux and 10G CWDM optical modules are even lower, making deployment more economical.

How to Deploy A 10G CWDM Network?

As stated above, the 10G CWDM SFP+ network has been widely deployed in various fields. Here are the common CWDM network infrastructures.

Point-to-point Configuration

Point-to-point CWDM networks are the most basic form of 10G CWDM SFP+ network, which can be expanded into more complex network systems by incorporating components such as CWDM OADMs.

Point-to-Point Dual-Fiber Link: clients can add or drop up to eight channels (whether it be Gigabit Ethernet or Fiber Channel) within a pair of single-mode fibers, substantially reducing the demand for additional fibers. For redundancy, backup channels can be added or removed within a second pair of single-mode fibers to establish a redundant point-to-point link. The following figure illustrates a point-to-point dual-fiber link with 4 wavelengths (lambda).

Point-to-Point Single-Fiber Link: By sending and receiving signals at different wavelengths within the same optical fiber, it's possible to transmit up to four channels on a single fiber. The following figure illustrates a point-to-point single-fiber link with 4 wavelengths (lambda).

Hub-and-spoke (ring) Configuration

In a hub-and-spoke (ring) configuration, numerous satellite nodes are connected to a central hub via a single-mode fiber ring. Each hub-to-node link can contain one or multiple channels, and the bidirectional connection of the fiber ring provides resilience against fiber cuts. This 10G CWDM SFP+ architecture is widely employed for service provider metropolitan access networks.

Mesh (ring) Configuration

Mesh deployments are a combination of hub-and-spoke and point-to-point or even multiple point-to-point connections in parallel on the same optical link.

CWDM SFP+ ring networks are suitable for interconnecting geographically dispersed local area networks (LANs) and storage area networks (SANs). Enterprises can benefit from CWDM technology by utilizing multiple gigabit Ethernet connections. As illustrated below, four buildings are interconnected by several 8-channel CWDM multiplexers/demultiplexers.

Internet Service Provider

10G CWDM modules significantly enhance the efficiency of optical fiber networks by transmitting multiple signals over a single fiber using different wavelengths. In the figure, the 10G CWDM modules connect two Cisco switches using a configuration that includes four 8-channel CWDM multiplexer/demultiplexer units, achieving high-capacity communication with just two optical fibers, thereby maximizing the potential of the existing infrastructure.
