Perle C-100-S2Lc40 100BASE-TX to 100Base-EX 1310nm LC 40km mount

SKU CH-KRWZ-5ZD3D

Converts 100BASE-TX to 100Base-EX single-mode fibre at 1310 nm over 40 km

  • TypeData & Communication
  • Extends Fast Ethernet to 40 km single-mode fibre
  • 1310 nm LC optics for reliable long-haul links
  • Converts 100BASE-TX copper to 100Base-EX fibre
  • 100 m RJ-45 reach for local device connection
  • Compact module fits standard media converter chassis

Fast Ethernet Media Converter Module

The Perle C-100-S2Lc40 converts 100BASE-TX signals over copper to 100Base-EX over single-mode fibre. It bridges RJ-45 connections up to 100 metres with LC connectors reaching 40 kilometres at 1310 nm wavelength. The module suits network engineers extending LAN segments across buildings or campuses.

Installers needing long-haul 100 Mbps links

Technicians who require a cost-effective way to join two Ethernet segments over single-mode fibre will find this converter fits the task. Buyers who need gigabit speeds, multi-mode fibre support, or Power over Ethernet should look at other models because this unit operates strictly at Fast Ethernet rates on single-mode cable.

Rack or wall-mount chassis integration

The converter slides into a compatible Perle chassis to draw power and share cooling with other modules. Using the LC single-mode port frees copper ports on switches for shorter runs while the 40 km reach eliminates intermediate repeaters. A matching 1310 nm module at the far end completes the link.

Questions about this item

What copper Ethernet port must my switch provide to connect to the C-100-S2Lc40?

The converter requires a 100BASE-TX RJ-45 port that supports 100 m or 328 ft cable runs.

Will the single-mode LC fibre link work with my existing 1310 nm optics?

Yes, the module uses 1310 nm single-mode LC connectors and is rated for 40 km or 24.9 miles.

How can I confirm the link is operating at the rated distance after installation?

Check that both the copper and fibre link LEDs are solid green and that the switch reports a 100 Mbps full-duplex connection.
