Perle media converter module with RJ-45 and ST connectors

Perle

Perle C-100-S2St40 100BASE-TX to 100Base-EX 40 km mount

SKU CH-HRHB-4BDP1

Converts 100BASE-TX copper to 100Base-EX single-mode fibre up to 40 km over ST connectors

  • TypeData & Communication
  • Converts copper to single-mode fibre for 40 km reach
  • RJ-45 port supports 100 m copper runs
  • 1310 nm wavelength suits long-haul links
  • ST connector ensures secure fibre termination
  • Fast Ethernet media conversion extends network distance

Media Converter for Long-Range Links

The Perle C-100-S2St40 bridges a 100BASE-TX copper port to a 100Base-EX single-mode fibre interface, extending Fast Ethernet connections up to 40 km. It serves network engineers and integrators who must span campuses, buildings or metro fibres without upgrading to gigabit hardware.

Sustained Operation Over Distance

The module maintains a steady 100 Mbps full-duplex rate across the full 40 km reach, limited only by the 1310 nm optics and link budget rather than burst buffers. Copper-side negotiation stays at 100 m, so traffic flows continuously without the throttling seen on shorter-range converters that overheat under constant load.

ST Connector and Chassis Mounting

An ST bulkhead secures the single-mode patch cord with a bayonet latch that resists vibration in rack or wall-mount trays. The compact form factor fits standard media-converter chassis, letting technicians stack multiple units without extra rack units or proprietary brackets.

Questions about this item

How much heat does the 100BASE-TX to 100Base-EX converter generate during continuous operation?

The module is a passive media converter with no internal fan, so it produces negligible heat and runs silently 24/7.

What cabling and patch panels must I already have to connect the RJ-45 and ST ports?

You need Cat5 or better copper patch cords for the 100 m RJ-45 side and 1310 nm single-mode fibre with ST connectors for the 40 km link.

Will the 100BASE-TX port negotiate with my older 10 Mbps hubs?

The RJ-45 interface is fixed at 100 Mbps full-duplex and does not auto-negotiate down to 10 Mbps.
