Overview

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.

Cisco CWDM Transceiver Modules

Cisco Coarse Wave Division Multiplexing (CWDM) Solution allows scalable and easy-to-deploy Gigabit Ethernet (GbE) and Fibre Channel services. The combination of CWDM GBICs and CWDM SFPs and CWDM Optical Add-Drop Modules (OADMs) and Multiplexers enables the design of a flexible and highly available multiservice network. The Cisco CWDM Solution offers a convenient and cost-effective solution for the adoption of optical Gigabit Ethernet in campus, data center, and metropolitan-area access networks.

 

Cisco CWDM Solution consists of a set of eight different Cisco CWDM GBICs (one for each of the eight different colors or wavelengths), 8 different SFPs, a set of 8 single wavelength/dual channel OADMs, two 4 channels OADM/MUX and an 8 channel MUX along with a CWDM rack mountable chassis.

Cisco CWDM GBIC and SFP Solution

Overview

The Cisco Coarse Wavelength-Division Multiplexing (CWDM) Gigabit Interface Converter (GBIC)/Small Form-Factor Pluggable (SFP) solution allows enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet and Fibre Channel services in their networks. The product set helps enable the flexible design of highly available, multiservice networks.

The Cisco CWDM GBIC/SFP solution is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fibre Channel in campus, data-center, and metropolitan-area access networks.

The Cisco CWDM GBIC/SFP solution has two main components (Figure 1): a set of eight different pluggable transceivers (Cisco CWDM GBICs and Cisco CWDM SFPs), and a set of different Cisco CWDM passive multiplexer/demultiplexer or optical add/drop multiplexers (OADMs). A Cisco CWDM chassis enables rack-mounting up to two of the Cisco CWDM passives. Both the transceivers and the passive multiplexers are compliant with the ITU-T G.694.2 standard defined CWDM grid.

Key Features and Benefits

Scalability

The Cisco CWDM GBIC/SFP solution helps enable the transport of up to eight channels (Gigabit Ethernet or Fibre Channel) over single-mode fiber strands.

Easy Deployment and Flexible Implementation

The Cisco CWDM GBIC (and Cisco CWDM SFP) fits into a standard GBIC (and SFP) port supporting the IEEE 802.3z standard on the supported Cisco Systems ® platforms. The Cisco CWDM OADM is passive and requires no power. Neither the Cisco CWDM GBIC (nor Cisco CWDM SFP) nor the Cisco CWDM passives requires configuration.

The Cisco CWDM GBIC/SFP solution allows for a variety of network configurations-from multichannel point-to-point to hub and meshed-ring configurations.

High Availability

The Cisco CWDM GBIC/SFP solution takes advantage of a multichannel architecture and the inherent protection of ring architectures. The solution helps enable:

• Use of Layer 2 and Layer 3 redundancy and failover mechanisms at the channel endpoints (Cisco CWDM GBIC/SFP) to build highly available links
• Use of two-path link configurations in a ring architecture to provide protection from fiber cuts

Investment Protection

The Cisco CWDM GBIC/SFP solution helps enable enterprises and service providers to increase the bandwidth of an existing Gigabit Ethernet optical infrastructure without adding new fiber strands. The solution can be used in parallel with other Cisco GBIC and SFP devices on the same platform.

What  is Solution To Cisco CWDM SFPs?

The term "solution" can mean different things in different contexts. I assume you're asking about what the "Cisco CWDM SFPs" offer or solve in a networking context.

Cisco CWDM (Coarse Wavelength Division Multiplexing) SFPs are a type of optical transceiver that Cisco provides for its switches and routers. CWDM is a type of WDM (Wavelength Division Multiplexing), which is a method used to increase the bandwidth of fiber optic networks by transmitting multiple wavelengths (or channels) of light on the same fiber.

Here are some key aspects and solutions provided by Cisco CWDM SFPs:

1. Increased Bandwidth: Cisco CWDM SFPs allow for multiple channels/wavelengths on a single fiber, effectively multiplying the bandwidth without needing to lay more fiber.

2. Cost-Effective: Deploying CWDM can be a cost-effective way to increase bandwidth since it avoids the need for extensive new infrastructure. You're essentially getting more out of your existing fiber.

3. Flexibility: Cisco's CWDM SFPs support a range of wavelengths, allowing for flexible channel planning.

4. Distance: Depending on the specific model and application, Cisco CWDM SFPs can support various distances, often ranging from a few kilometers to tens of kilometers.

5. Interoperability: Cisco CWDM SFPs are designed to be compatible with a wide range of Cisco switches, routers, and other hardware.

6. Monitoring and Diagnostics: Some of Cisco's CWDM SFPs offer digital optical monitoring capabilities, allowing for real-time monitoring of the transceiver's operating parameters.

7. Applications: Ideal for use in metropolitan area networks (MANs), where distances between network nodes are longer than what's typically seen in a local area network but shorter than in a wide-area network.

In summary, the solution provided by Cisco CWDM SFPs is that they offer an effective way to expand the bandwidth of existing optical networks by multiplexing multiple wavelengths onto a single fiber. This offers a balance between cost, bandwidth expansion, and performance for network administrators.
