Industrial Copper-to-Fibre Converter

The Perle Sr-1110-St05-Xt converts 10/100/1000BASE-T signals over RJ-45 copper up to 100 m to 1000BASE-SX multimode fibre at 850 nm up to 550 m. It operates in a DIN-rail enclosure powered through a Combicon terminal block for external supply. Extended temperature tolerance spans -40 °C to +75 °C. Maximum frame size is 10,240 bytes.

Suited for Harsh Environment Links

This unit serves installers who need reliable copper-to-fibre conversion across wide temperature ranges in industrial cabinets or outdoor enclosures. It does not suit buyers who require single-mode reach beyond 550 m or Power-over-Ethernet injection. It also excludes users needing managed switching features or redundant ring protocols.

Multimode ST Reach 550 m

The single decisive specification is the 1000BASE-SX multimode ST interface limited to 550 m or 1804 ft. If the link distance or fibre type differs, this converter will not meet the requirement.

Questions about this item

Which speed combination should I choose for my network links?

The converter handles 10/100/1000BASE-T on the copper side and 1000BASE-SX on the fibre side, so it matches gigabit Ethernet over both media.

What does the 1000BASE-SX rating mean once the unit is installed?

It delivers 1 Gb/s over 850 nm multimode fibre up to 550 m or 1804 ft, while the RJ-45 port reaches 100 m or 328 ft on twisted pair.

How does the ST connector limit the link in practice?

The ST interface caps the fibre segment to the 550 m multimode distance and requires matching ST patch cords on both ends.
