  • TypeData & Communication
  • Converts 100BASE-TX to 100Base-EX single mode
  • Extends fibre links up to 40 km
  • RJ-45 copper reach of 100 m / 328 ft
  • Operates at 1310 nm wavelength for single-mode fibre
  • Includes USA power cord for immediate deployment

Media Converter Mount for 40 km Single-Mode Links

The Perle S-100-S2St40 mount secures a Fast Ethernet media converter that bridges 100BASE-TX copper to 100Base-EX single-mode fibre. It is built for network engineers extending LAN segments across campus or metro distances up to 40 km. The bracket fits standard rack or wall-mount environments where the converter must stay fixed.

Upgrade from Short-Range or Multimode Fibre

This mount supports a converter that replaces 100BASE-FX multimode links limited to 2 km or 100BASE-TX copper capped at 100 m. The jump is worth it when the path exceeds 328 ft and single-mode fibre at 1310 nm is already installed or planned. It is not for buyers who need Gigabit or 10 Gigabit throughput, or who require a managed switch with multiple ports.

Simple Rack or Wall Installation

The bracket uses standard mounting holes so the converter slides in and locks without tools. Power connects via the included USA cord. The only common issue is mismatched ST polishing on the fibre patch cord, which causes link failure until the correct single-mode ST connector is fitted.

Questions about this item

What mounting hardware is required for the S-100-S2St40 media converter?

The unit is a standalone media converter with an included USA power cord; no rack rails, brackets or DIN clips are mentioned in the specifications.

How is the fibre link connected during installation, and what step is often missed?

Connect the 1310 nm single-mode fibre to the ST connector; the step often missed is confirming the link budget supports the full 40 km distance.

Which components will need replacement over the life of the S-100-S2St40?

The AC power cord and the ST patch cord are the only field-replaceable items; the converter itself has no user-serviceable parts.
