Walsun 10G SFP+ CWDM Transceiver Module

About Walsun 10G SFP+ CWDM Optical Transceiver Module in Bangladesh

The Walsun 10G SFP+ CWDM Optical Transceiver is a high-speed wavelength-division-multiplexing module designed for 10Gbps networking over single-mode fiber. It uses Coarse Wavelength Division Multiplexing (CWDM) technology to transmit different optical wavelengths over the same fiber infrastructure, helping network operators increase fiber capacity without installing additional fiber pairs.

Walsun's official 10G SFP+ CWDM product family supports data links up to 11.3Gbps, duplex LC/UPC connectivity, digital diagnostics, a 3.3V power supply and single-mode fiber. Depending on the specific wavelength and reach variant, Walsun offers 10km, 40km, 80km and 100km configurations. Walsun official 10G SFP+ CWDM specifications

The CWDM family covers wavelengths from 1270nm to 1610nm with 20nm channel spacing. This makes the modules suitable for CWDM multiplexing systems used in metro networks, enterprise backbones, telecom infrastructure, data center interconnection and access networks. Walsun CWDM technical guide

Walsun 10G SFP+ CWDM Specifications & Features

Overview

The Walsun 10G SFP+ CWDM series provides scalable optical connectivity for networks where multiple 10Gbps channels need to share the same fiber infrastructure. By assigning each optical transceiver a different CWDM wavelength, multiple independent signals can be multiplexed onto a single fiber pair through a compatible CWDM multiplexer/demultiplexer.

Walsun's product family includes different reach and wavelength variants, allowing the module to be selected according to the required optical distance and network architecture. Walsun product family

What is 10G CWDM SFP+?

A 10G CWDM SFP+ optical transceiver is an optical networking module that uses a specific wavelength within the CWDM spectrum to transmit 10Gbps data over single-mode fiber.

CWDM allows multiple optical signals at different wavelengths to travel through the same fiber. At the destination, a CWDM demultiplexer separates the individual wavelengths and directs them to their respective optical receivers.

Walsun identifies its 10G CWDM SFP+ family as a solution for increasing fiber utilization in metro and access networks. Walsun CWDM SFP+ technical information

1270nm–1610nm CWDM Wavelengths

The Walsun 10G SFP+ CWDM family supports selectable wavelengths across the CWDM range from 1270nm to 1610nm, with 20nm spacing between channels.

The exact wavelength should be selected according to the CWDM multiplexer/demultiplexer channel plan. Modules at different wavelengths are normally used together to create a multi-channel CWDM link.

Available Transmission Distances

Walsun offers several 10G SFP+ CWDM configurations. The official ordering table lists 10km, 40km, 80km and 100km variants. Walsun ordering information

Because the product name "10G SFP+ CWDM" covers multiple Walsun variants, the exact wavelength, distance and ordering code should be confirmed when purchasing.

10km CWDM SFP+ Module

The 10km variant uses a DFB transmitter and PIN receiver. Walsun lists transmit power from approximately -6 to -0.5dBm and receiver sensitivity better than -14.4dBm for this configuration. Walsun specifications

This version is suitable for shorter metro, enterprise and campus fiber links.

40km CWDM SFP+ Module

The 40km variant uses an EML transmitter and PIN receiver. Walsun lists transmit power from approximately -1 to +3dBm and receiver sensitivity better than -15.8dBm.

It is suitable for longer enterprise backbone, metro access and regional fiber applications.

80km CWDM SFP+ Module

The 80km variant uses an EML transmitter with an APD receiver. Walsun specifies approximately 0 to +5dBm transmit power and receiver sensitivity better than -23dBm. Walsun official specifications

This version is intended for long-distance single-mode fiber links where a higher optical budget is required.

100km CWDM SFP+ Module

The 100km variant uses an EML transmitter and APD receiver. Walsun lists transmit power of approximately +1 to +6dBm and receiver sensitivity better than -25dBm.

Long-distance 100km deployments should be engineered carefully for fiber attenuation, dispersion, connector losses and the complete optical link budget.

Duplex LC/UPC Interface

Walsun's 10G SFP+ CWDM modules use a duplex LC/UPC optical interface. One fiber is used for transmission and the other for reception.

The optical module itself does not perform wavelength multiplexing of multiple channels. A compatible CWDM multiplexer/demultiplexer is required when multiple CWDM wavelengths are combined onto shared fiber infrastructure.

Digital Diagnostic Monitoring

The Walsun 10G SFP+ CWDM family supports a digital diagnostic interface. Compatible networking equipment can monitor important operating parameters of the optical module.

DDM/DOM can assist administrators in monitoring optical power, module temperature, supply voltage and laser operating conditions, depending on host-platform support.

Hot-Pluggable SFP+ Design

The module uses the standard compact SFP+ form factor and is designed for hot-pluggable installation in compatible networking equipment.

This allows network administrators to install or replace optical modules without replacing the entire switch, router or network interface.

3.3V Power Supply

Walsun specifies a single +3.3V power supply for the 10G SFP+ CWDM module family. The low-power SFP+ architecture is suitable for high-density network deployments.

Compatibility

Walsun states that its 10G SFP+ optical modules support multiple coding options for mainstream networking equipment and offers compatibility with major vendors. Walsun 10G SFP+ selection guide

When ordering, the exact switch, router, NIC or optical transport platform should be specified so the appropriate vendor-coded module can be supplied.

10G CWDM vs 10G DWDM

CWDM is often selected where cost-effective wavelength multiplexing and moderate channel density are required, while DWDM is better suited to high-density wavelength systems and long-distance optical transport.
