Network transceiver module Extralink EX.33249 SFP fiber optic 800000 Mbit/s

Extralink EX.33249 is an SFP fiber optic transceiver module designed to provide optical connectivity for network devices with SFP ports. With a maximum data transfer rate of 800000 Mbit/s, this module is intended for high-capacity links in switches, routers and media converters that accept SFP fiber modules. The module supports standard SFP form-factor installation and enables optical transmission over single-mode fiber using duplex LC connections where applicable.

Advantages

The Extralink EX.33249 provides a compact SFP form factor that simplifies deployment in existing networking equipment. Its high maximum data transfer rate supports bandwidth-intensive applications and aggregation links. The transceiver's optical interface reduces susceptibility to electromagnetic interference and enables longer-distance links compared with copper connections when paired with appropriate fiber cabling and optics.

Suitable for

• High-capacity uplink and aggregation ports in switches and routers
• Media converters and optical network modules requiring SFP transceivers
• Point-to-point single-mode fiber links where duplex LC connections are used
• Environments that require optical connectivity to reduce EMI and extend link distance

When it may not be suitable

This SFP fiber optic transceiver is not suitable for devices that lack SFP ports or require different form factors (for example QSFP or SFP+). It is also not appropriate where only copper-based Ethernet ports are supported or when multimode fiber termination is required unless the module specifically supports that fiber type.

Key specifications

• Form factor: SFP
• Optical medium: fiber optic (single-mode expected for long-reach links)
• Maximum data transfer rate: 800000 Mbit/s
• Connector type: duplex LC (typical for SFP fiber transceivers)

How to use

Install the Extralink EX.33249 into an available SFP slot on a compatible switch, router or media converter while the device is powered down or following the manufacturer's hot-swap guidance. Connect compatible single-mode duplex LC fiber patch cables between network endpoints and ensure fiber polarity is correct. After insertion, verify link status in the device management interface and monitor for correct module recognition and operational parameters. Follow standard safety practices for handling fiber optics, including avoiding looking into active fiber ends.

What to consider before purchase

• Confirm that the target device has an SFP port that accepts third-party SFP modules
• Verify the fiber type (single-mode vs multimode) and connector type required for your link
• Ensure the maximum data rate and optical reach match your network requirements
• Check device compatibility and firmware requirements with the module

Usage recommendations

Use certified single-mode duplex LC fiber patch cables and verify polarity; after installation check the device interface for correct recognition and run diagnostics or link tests to confirm expected throughput and signal quality.
