Perle C-110-S2LC20 SFP transceiver

The Perle C-110-S2LC20 is a compact SFP transceiver that provides a single LC duplex fibre port and one RJ-45 copper port. It operates at 10/100Base-TX on the copper side and 100Base-LX on the fibre side, enabling network administrators to extend Ethernet links over single-mode fibre. The module is designed for use inside a high-density Perle Media Converter Chassis and carries a new condition.

Network extension for legacy 10/100 links

This transceiver suits IT teams that need to connect older 10/100 Ethernet equipment across campus or metro distances using single-mode fibre. It supports Auto-Negotiation, Auto-MDIX, Link Pass-Through, Far End Fault and Remote Loopback for simplified troubleshooting. Buyers who require Gigabit or 10 Gigabit throughput, multi-mode fibre support, or additional port density on a single module should consider other options.

12.43 mile maximum reach on single-mode fibre

The decisive specification is the 12.43 mile (20 kilometre) maximum distance rating on the 100Base-LX interface. This range determines whether the transceiver can bridge the required link between two sites or buildings. If the planned fibre run exceeds this distance, a different optic with a longer reach will be necessary.

Questions about this item

How much heat does the 100Base-LX SFP module generate when running continuously?

The module operates passively without a fan and draws minimal power typical of 100 Mbps SFP transceivers, so heat output stays low during all-day use.

What chassis or switch slot is required to install the C-110-S2LC20 transceiver?

It fits any standard SFP port on a Perle Media Converter Chassis or compatible network switch with an open SFP cage.

Will the 12.43 Mile link work with older 10/100Base-TX copper equipment on the RJ-45 side?

Yes, the RJ-45 port auto-negotiates 10 or 100 Mbps and supports Auto-MDIX, so legacy copper devices connect without crossover cables.
