Perle S-110-S2St40 Media Converter

The Perle S-110-S2St40 is a 10/100Base-TX to 100Base-EX media converter designed for network extension. It connects copper cabling at 100 metres to single-mode fibre at 40 kilometres. The unit handles a maximum frame size of 2048 bytes. It includes a USA power cord for immediate deployment.

Suited for long-distance copper-to-fibre links

This converter suits installers bridging LAN segments over 40 km single-mode fibre using ST connectors. It supports 1310nm wavelength transmission for reliable data communication. Buyers needing multimode fibre, SC connectors, or Gigabit Ethernet speeds should look at other models. It does not fit applications requiring higher bandwidth or different optical interfaces.

40 km reach with 2048 byte frames

The link comfortably handles 100 Mbps traffic across 40 km or 24.9 miles of single-mode fibre. Copper segments run up to 100 metres or 328 feet from the RJ-45 port. Maximum frame size of 2048 bytes sets the upper limit for packet forwarding. Jumbo frames exceeding this size will not pass through the converter.

Questions about this item

What type of copper port does the S-110-S2St40 require on the network switch?

The converter connects through a 10/100Base-TX RJ-45 port on the switch side.

Will the 100Base-EX 1310nm single-mode fibre link work with my existing 100Base-FX multi-mode cabling?

No, the 1310 nm single-mode interface requires matching single-mode fibre; multi-mode cable will not work.

How can I confirm the link is operating at the full 40 km distance after installation?

Verify the link LED is solid and check that the attached equipment negotiates 100 Mbps full-duplex with no frame errors.
