Silicom’s SL-SFP-1G-SX Small Form Factor Pluggable (SFP) transceivers have been designed to provide seamless connectivity for network interface cards (NICs) within a network. The transceivers comply with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), ensuring that they are compatible and interoperable with a wide range of networking equipment.

The SL-SFP-1G-SX transceivers offer high-performance and cost-effective solutions, supporting a dual data-rate of 1.25Gbps/1.063Gbps. They can transmit data up to 500 meters using multimode fiber (MMF), making them ideal for short to medium-range network links.

Silicom’s SL-SFP-1G-SX transceivers are compliant with RoHS regulations and are lead-free, demonstrating the company’s commitment to environmental sustainability.

The SL-SFP-1G-SX transceivers boast key features such as support for data links up to 1.25Gb/s, ensuring efficient and reliable data transfer. These transceivers come equipped with a duplex LC connector that allows for easy and secure connections with fiber optic cables. Additionally, they are hot-pluggable and designed to fit into a standard SFP footprint, making installation and replacement convenient.

The SL-SFP-1G-SX transceivers are equipped with a 1310nm FP (Fabry-Perot) laser transmitter that provides exceptional optical signal transmission. These transceivers are enclosed in a metal casing that effectively minimizes electromagnetic interference (EMI) and guarantees stable network performance.

These transceivers operate on a single +3.3V power supply, contributing to their power efficiency. They have low power dissipation of less than 800mW within a temperature range of 0 to 70 degrees Celsius, which minimizes energy consumption while maintaining optimal performance.

Silicom’s SL-SFP-1G-SX transceivers provide flexibility with optional commercial operating temperature ranges, enabling reliable operation in various environmental conditions. These transceivers offer high-performance, cost-effective, and environmentally-friendly connectivity solutions for NICs in network infrastructures. Compliance with industry standards, low power consumption, and EMI reduction are key features, and the ability to support data links up to 1.25Gb/s and transmission distances of up to 500 meters with MMF make these transceivers a reliable choice for seamless NIC connectivity within networks.
