IMC-101-S-SC-T

What does this device do in an Ethernet network?

It converts a copper Ethernet connection (10/100BaseT(X) over RJ45) to fibre Ethernet (100BaseFX), allowing you to extend network links over single‑mode fibre while maintaining standard Ethernet connectivity.

Which fibre connector type does it use?

It uses an SC fibre connector for the 100BaseFX fibre port (single‑mode).

Is it single-mode or multi-mode fibre?

This variant is designed for single‑mode fibre (100BaseFX), suitable for longer point‑to‑point links than typical multi‑mode installations.

What fibre distance can I expect in typical installations?

The single‑mode (40 km class) optical interface is typically specified for up to 40 km, assuming appropriate fibre type, connectors/splices, and link-loss budget.

What Ethernet speeds does it support on the copper side?

The RJ45 port supports 10/100 Mbps with auto‑negotiation, so it can adapt to connected equipment running either 10BaseT or 100BaseTX.

Does the RJ45 port support auto MDI/MDI-X?

Yes. The copper port supports auto MDI/MDI‑X, which helps simplify cabling by reducing the need to consider crossover vs. straight‑through cables.

What is the operating temperature range for this version?

This is the wide‑temperature “-T” variant, designed for operation from -40 to 75°C, which is useful for harsher industrial environments.

What power input does it require?

It accepts 12 to 45 VDC via a terminal block. Typical current draw is specified at 200 mA within that input range.

Does it support redundant power wiring?

Yes, it supports redundant DC power inputs, helping you design a more resilient power arrangement using two independent feeds.

Is there any alarm output for power or link issues?

Yes. It provides a relay output that can be used to signal events such as power failure and port link down, enabling integration with external monitoring or alarm circuits.

What is LFPT and does this unit provide it?

LFPT (Link Fault Pass-Through) helps propagate a link fault from one side of the converter to the other, making it easier to detect breaks or disconnections through connected network equipment. This unit supports LFPT functionality.

How is it typically installed inside a control cabinet?

It is designed for DIN‑rail mounting and uses a metal housing with an IP30 rating, making it suitable for installation within industrial enclosures.

What are the approximate physical dimensions and weight?

The housing is approximately 53.6 × 135 × 105 mm and weighs about 630 g, which helps when planning DIN‑rail space and panel layout.

Are there any recommendations when connecting single-mode fibre transceivers?

Where optical power could be excessive for the receive side, an optical attenuator may be recommended to avoid potential receiver overload. This is a common consideration on short single‑mode runs with higher‑power optics. For reference, this unit is often supplied as IMC-101-S-SC-T.
