3Com 3C17710 4-Port 1000Base-SX Module for Switch 4900 and Switch 40x0

Overview
The 3Com 4-Port 1000Base-SX Module (part number 3C17710) is a compact, hot-swap optical transceiver designed for the 3Com Switch 4900 series and Switch 40x0 series. It provides four independent gigabit fiber connections in a single, space-saving module, allowing network administrators to expand bandwidth while keeping cabling neat and reliable. This module is ideal for campus, enterprise, and data-center environments where high-speed, short-range fiber links are required.

Key Features

• Four 1000Base-SX ports in a single module for dense port aggregation
• Supports multimode fiber (MMF) up to 550 meters with standard 850 nm lasers
• Hot-swap capable - install or replace without powering down the switch
• Fully compliant with IEEE 802.3z standards for gigabit Ethernet
• Low power consumption helps reduce overall data-center energy costs
• Plug-and-play design simplifies deployment and reduces installation time

• Dimensions: standard 3Com SFP form factor, fits in any 3Com Switch 4900 or 40x0 chassis

Applications
The 3C17710 module is suited for a variety of high-performance networking scenarios, including:

• Connecting server farms to core switches with short-run multimode fiber
• Building-to-building links in campus networks where low latency is critical
• Extending storage area networks (SAN) that rely on gigabit fiber connectivity
• Providing redundant uplinks for high-availability environments
• Upgrading legacy copper ports to fiber without replacing the entire switch

By delivering four reliable gigabit fiber ports in a single, easy-to-install module, the 3Com 4-Port 1000Base-SX solution helps organizations scale their networks efficiently while maintaining high performance and low operational overhead.
