  • Operates at 1310 nm wavelength on both ports
  • Supports 100 Mbps data rate across media types
  • Includes USA power cord for immediate deployment

Product Identity

The Perle 05060074 S-100Mm-S2St40 is a Fast Ethernet media converter designed for network integrators and infrastructure teams. It bridges 100BASE-FX 1310nm multimode ST fibre over 1.2 miles to 100Base-EX 1310nm single mode ST fibre up to 24.9 miles. A USA power cord is included for immediate deployment.

Upgrade Scope

This unit replaces a direct multimode link when the required span exceeds the 2 km native limit. The jump is justified when a campus or metro segment demands 40 km reach without upgrading line-rate electronics. It is not suited for gigabit or 10-gigabit links, nor for networks that require SFP flexibility instead of fixed ST connectors.

Installation Notes

Mount the converter in a standard rack or shelf, connect the two ST patch cords, and apply mains power. The fixed ST interfaces remove transceiver compatibility checks, but they also prevent future connector changes. Verify that both fibre strands are 1310 nm and that link budget matches the 40 km single-mode path before commissioning.

Questions about this item

What mounting hardware or rack space does the Perle S-100Mm-S2St40 require?

The unit is a standalone media converter; no rack-mount brackets or DIN-rail clips are included, so it simply rests on a flat surface or shelf near the fibre patch panel.

Which fibre connectors must be plugged in first during installation, and what common mistake should be avoided?

Connect the 1310 nm multimode ST cable to the 2 km port and the 1310 nm single-mode ST cable to the 40 km port; the frequent error is swapping the two fibres, which breaks the link.

When should the USA power cord or the converter itself be replaced?

Replace the power cord if the plug or insulation shows damage; replace the converter if the 100BASE-FX or 100BASE-EX ports no longer establish a link over their rated 2 km and 40 km distances.
