Perle C-100-S2SC20 100Base-LX transceiver

The Perle C-100-S2SC20 is a single-port SFP transceiver built for 100Base-LX fibre links. It installs inside a high-density Perle Media Converter Chassis to connect 10/100Base-TX copper equipment to single-mode fibre networks. Network administrators managing campus or metro links use it to extend legacy Fast Ethernet segments beyond copper limits.

Distance and interface constraints

The module reaches 12.43 Mile over a duplex SC single-mode fibre pair. It operates at the 100Base-LX standard, so the line rate is fixed at 100 Mbps full-duplex and cannot negotiate Gigabit speeds. Auto-negotiation and auto-MDIX apply only to the copper RJ-45 side; the fibre port has no speed fallback. Link Pass-Through and Far End Fault help diagnose breaks but do not increase bandwidth.

Chassis and patch-cord checks

Confirm you have a compatible Perle Media Converter Chassis with a free SFP slot before ordering. Verify that your fibre plant uses duplex SC connectors and single-mode cable rated for the required span. Ensure the copper patch cord to the RJ-45 port is Category 5 or better to support 100Base-TX without errors.

Questions about this item

Which distance rating should I pick for a 12.43 Mile link?

Choose the 12.43 Mile variant; it is built for single-mode fiber spans up to that length.

What throughput will I see on a 100Base-LX port in daily use?

The port runs at 100 Mbps full-duplex, so sustained file transfers sit near 100 Mbps.

Does the SC duplex interface limit the 12.43 Mile reach?

No; the SC duplex connector is the standard mating face for the 12.43 Mile single-mode optic.
