Perle 100BASE-EX 40 km media converter

The Perle SMI-100-S2LC40 converts 100BASE-TX copper links to 100BASE-EX single-mode fibre. It extends a Fast Ethernet segment up to 40 km over a 1310 nm wavelength. Network engineers use it to bridge buildings or campus sites without signal repeaters.

Single-mode LC fibre interface

The LC connector and 1310 nm optics replace the standard RJ-45 reach of 100 m. This change lets the same 100 Mbps data rate travel 24.9 miles on a single fibre strand. No media conversion software is required; the unit operates transparently at Layer 1.

Fast Ethernet distance headroom

The converter comfortably handles full-duplex 100 Mbps traffic across the full 40 km span. It runs out of reach beyond the rated single-mode distance or if multimode fibre is substituted. Buyers needing Gigabit speeds or multimode compatibility must select a different model.

Questions about this item

Will the LC single-mode fibre connector need periodic cleaning to keep the 40 km link reliable?

Yes, the LC single-mode connector should be inspected and cleaned before installation and whenever the link is disconnected, because contamination on the 1310 nm optical interface is the most common cause of signal loss on a 40 km span.

What is the first limit reached when the converter runs continuously at 100BASE-TX wire speed?

The 100 m copper segment distance is the first hard limit; the RJ-45 port only supports 100BASE-TX up to 100 m, while the fibre side is rated for 40 km.

How much heat does the unit add to a rack when it operates 24/7 with the USA power cord?

The converter is a passive media converter with no internal fan, so it adds only the low heat typical of a 100 Mb/s Fast Ethernet device and requires no active cooling in a ventilated rack.
