2km SX SFP Module – 1.25G 1310nm Multimode Optical Transceiver

Product Overview

The WOLON 1310nm 2km SX SFP Module is a specialized optical transceiver designed to extend Gigabit Ethernet connections beyond the standard 550m limit of traditional 850nm modules. While standard SFP SX transceivers are limited to short ranges, this module utilizes a 1310nm wavelength to achieve a transmission distance of up to 2km over Multimode Fiber (MMF).

This solution is perfect for campus backbones or building-to-building connections where Multimode fiber is already installed, but the distance exceeds the capabilities of a standard 1000BASE SX SFP transceiver. It offers a cost-effective alternative to replacing existing fiber cabling with Single-mode fiber.

Key Features

• Longer Distance on MMF: Supports up to 2km link lengths on legacy multimode fiber, far exceeding the 550m limit of standard SFP-SX.

• 1310nm Technology: Uses a high-quality 1310nm FP laser transmitter tailored for multimode dispersion performance.

• Cost-Effective Upgrade: Avoids the expensive need to re-cable infrastructure to Single-mode fiber for mid-range distances.

• Universal Compatibility: Fully compliant with SFP MSA and SFF-8472, functioning seamlessly as a long-reach 1000BASE SX SFP module.

• Robust Design: Low power consumption and metal enclosure for excellent EMI performance.

Application Scenarios

This 1000BASE SX SFP transceiver (2km variant) is ideal for specific networking challenges:

1. Campus Networking: Connecting buildings that are 1km-2km apart where only OM2/OM3 Multimode fiber is available.

2. Legacy Infrastructure Upgrade: Extending network reach in older facilities without the high cost of laying new Single-mode cables.

3. Industrial Connections: Reliable mid-range data transmission in factory environments.

4. Enterprise Backbones: Connecting remote wiring closets that are just beyond the reach of standard 850nm SFP SX optics.
