In modern communication networks, optical transceivers are vital for high-speed data transmission. Among them, the SFP+ 10G DWDM 80KM transceiver stands out for its ability to support long-distance and high-capacity communication, making it ideal for metro networks, data centers, and telecom infrastructures.

What is an SFP+ 10G DWDM 80KM Transceiver?

This transceiver combines two key technologies:

• SFP+ (Small Form-factor Pluggable Plus): A compact, hot-swappable optical module designed for 10Gbps Ethernet applications.

• DWDM (Dense Wavelength Division Multiplexing): A technology that enables multiple data streams, each using a different wavelength, to be transmitted over a single optical fiber.

Together, these features allow the module to deliver 10Gbps transmission over distances up to 80 kilometers without signal regeneration.

How It Works

The transceiver converts electrical signals into optical signals and vice versa. Using DWDM, it can carry multiple wavelengths over the same fiber. Each channel operates independently, preventing interference and maximizing bandwidth efficiency.

To support long distances, the module uses 1550nm long-wavelength lasers and integrated optical amplifiers. These components reduce signal attenuation and distortion, ensuring signal integrity over 80KM.

Why Choose SFP+ 10G DWDM 80KM?

1. Long-Distance Performance

This transceiver is optimized for point-to-point links up to 80KM, eliminating the need for additional repeaters. It’s a cost-effective solution for interconnecting distant sites.

2. High Bandwidth Density

Thanks to DWDM technology, a single fiber can carry dozens of 10Gbps channels, multiplying bandwidth capacity without laying new fiber. This is especially beneficial for high-traffic environments like data centers and ISPs.

3. Lower Infrastructure Costs

By maximizing fiber utilization and reducing the need for regeneration hardware, network operators can save significantly on fiber leasing and equipment costs.

4. Easy Network Scalability

Network upgrades can be achieved by simply adding or replacing transceivers—no need to rewire or install new infrastructure. This flexibility supports business growth with minimal disruption.

Common Applications

• Metropolitan Area Networks (MANs)

• Inter-data center connectivity

• Long-haul telecom backbones

• 4G/5G mobile backhaul
