10G CWDM SFP+ Optical Transceivers
Scalable Bandwidth with 10G CWDM Technology

Our 10G CWDM SFP+ (Coarse Wavelength Division Multiplexing) transceivers allow you to maximize your existing fiber infrastructure by transmitting up to 18 independent channels over a single pair of single-mode fibers. This is the most cost-effective solution for increasing bandwidth in metropolitan area networks (MAN), campus backbones, and enterprise storage networks without the high cost of installing new fiber.

Technical Specifications:

• Wavelength Range: Full support for the ITU G.694.2 standard, ranging from 1270nm to 1610nm (20nm spacing).

• Extended Reach: Standard configurations support distances of 10km, 40km, and 80km.

• Protocol Support: Fully compliant with 10G Ethernet, 10G Fiber Channel, and OTU2/OTU2e.

• Compatibility: Our modules are coded and tested to be 100% compatible with Cisco, HP, Arista, Juniper, and other major OEM platforms.

Why Use CWDM SFP+? By using different wavelengths (colors) for each data stream, CWDM SFP+ modules enable passive multiplexing. This allows a single fiber link to carry multiple 10Gbps signals simultaneously. All Compufox CWDM modules feature Digital Optical Monitoring (DOM), providing real-time access to operating parameters such as laser bias current and transceiver temperature

10G CWDM Wavelength Selection Guide

10G CWDM SFP+ optical transceivers use Coarse Wavelength Division Multiplexing (CWDM) to transmit multiple 10G signals over the same pair of single-mode fibers. Each transceiver operates on a specific wavelength, and correct wavelength selection is critical for proper network operation.

How CWDM Works

CWDM assigns each optical signal a unique wavelength, spaced 20 nm apart, allowing multiple channels to coexist on the same fiber using CWDM multiplexers (MUX) and demultiplexers (DEMUX).

Standard 10G CWDM Wavelengths

Important CWDM Selection Rules

• Both ends of the fiber link must use the same CWDM wavelength.
• CWDM transceivers require CWDM MUX/DEMUX equipment to combine and separate wavelengths.
• Do not mix CWDM optics with standard LR or BiDi optics on the same MUX channel.
• Ensure all CWDM modules support the same distance and optical power budget.

When to Choose CWDM

• You need to run multiple 10G links over limited fiber
• You want a lower-cost alternative to DWDM
• Typical distances range from 10 km to 80 km
