Product Features
Technical Overview
This SFP module operates on Gigabit Ethernet technology, specifically 1000Base-T, which utilizes all four pairs of Category 5e or higher twisted pair cable to achieve full-duplex communication. It supports a maximum distance of 0.10 km (approximately 328 feet), making it suitable for connecting devices within server rooms, office floors, or between adjacent network cabinets. The 1.25 Gbit/s data transfer rate ensures efficient handling of high-bandwidth applications without bottlenecks.
The module features a single RJ-45 port, providing a direct copper interface for network devices. Its hot-pluggable and hot-swappable design allows for installation or replacement without powering down the host equipment, minimizing network downtime during maintenance or upgrades. This capability is essential for environments requiring continuous operation and quick hardware adjustments.
Key Product Advantages
The Omada SM331T SFP Module offers several advantages for network administrators seeking reliable copper connectivity in SFP-based systems. Its compatibility with standard twisted pair cabling reduces infrastructure costs compared to fiber optics, while maintaining Gigabit performance for most enterprise needs. The hot-pluggable feature enhances operational flexibility, allowing for quick swaps during network reconfigurations or fault isolation without disrupting other services.
Cost-Effective Copper Integration
Leverage existing Cat5e/Cat6 cabling investments by adding this module to SFP ports, avoiding the expense of fiber transceivers and cables for short-distance links.
- Uses standard twisted pair media
- Eliminates need for fiber conversion in some scenarios
Operational Flexibility
Hot-pluggable design supports live insertion and removal, enabling maintenance and upgrades without network downtime, critical for high-availability environments.
- Minimizes service interruptions
- Facilitates rapid hardware changes
Deployment / Use Cases
This module is ideal for extending copper network segments into devices with SFP slots, such as managed switches, routers, or media converters. Common use cases include connecting servers, workstations, or IP phones to a core switch via copper cabling, where the switch has SFP uplink ports. It also serves in data center environments to link top-of-rack switches to aggregation layers using cost-effective copper runs instead of fiber for distances under 100 meters.
In optical network deployments, the module can act as a copper interface for network monitoring equipment or legacy devices that lack fiber ports. Its small form factor and low power consumption make it suitable for dense installations where space and heat management are concerns. Network upgrades benefit from its plug-and-play installation, reducing deployment time and complexity.
Physical Profile
The module measures 0.50 inches in height, 2.70 inches in width, and 0.50 inches in depth (12.70 mm x 68.58 mm x 12.70 mm), conforming to the standard SFP dimensions for seamless fit in compatible slots. Its compact size ensures it does not obstruct adjacent ports or airflow in densely packed networking equipment. The design supports vertical or horizontal orientation as per host device specifications, with a sturdy construction that withstands repeated insertions and removals.
