Network transceiver for copper-to-fibre links

The Perle SR-100-ST20 is a 100Base-LX/TX SFP transceiver built for extending Ethernet over single-mode fibre. It suits network operators who need a managed, hot-swappable module to bridge copper and fibre segments in enterprise or campus environments.

Thermals noise and power in normal use

The module draws 20 watts during operation, keeping heat output modest for dense switch deployments. Passive cooling and no moving parts mean silent running in rack cabinets or wall-mounted enclosures.

Build integration requirements and freedoms

The SFP form factor slots directly into compatible switches, routers or media converters without extra cabling. It frees up copper ports for local devices while delivering a 100 Mbps fibre uplink up to 20 kilometres.

Questions about this item

How is the Perle SR-100-ST20 installed in a switch?

Insert the transceiver into an available SFP slot until it clicks firmly into place; the step often missed is removing the dust caps from both the module and the fiber cable before connecting the ST duplex link.

What maintenance or replacement will the Perle SR-100-ST20 need over time?

The optical interfaces should be inspected and cleaned with a lint-free swab and isopropyl alcohol whenever signal loss appears; replace the module if the 100Base-LX link fails to establish after cleaning.

What distance limit applies to the Perle SR-100-ST20 under continuous operation?

The 100Base-LX specification supports up to 20 km over single-mode fiber; sustained use does not reduce this reach, but excessive connector loss or cable damage will degrade the link first.
