Operating Principle
The CS-100C-M30 is installed between a standard Ethernet device and a fiber optic link. An RJ45 network cable connects to the copper side of the media converter, while duplex multimode fiber connects to the optical side.
Typical connection:
Ethernet Device → RJ45 → CS-100C-M30 → Multimode Fiber → CS-100C-M30 → RJ45 → Ethernet Device
This configuration allows two remote Ethernet segments to be connected without modifying the existing active network equipment.
10/100Base-TX Ethernet Port
The copper interface of the media converter uses a standard RJ45 port and supports 10Base-T and 100Base-TX.
A standard Cat5 or higher Ethernet cable compliant with EIA/TIA 568A/B can be used for the connection.
| Parameter | Value |
|---|---|
| Port type | RJ45 |
| Data rate | 10 / 100 Mbit/s |
| Standards | IEEE 802.3 10Base-T, IEEE 802.3u 100Base-TX |
| Cable | Cat5 or higher |
| Pinout | EIA/TIA 568A/B |
100Base-FX Optical Interface
The optical interface of the CS-100C-M30 operates according to the 100Base-FX standard and uses two SC connectors for optical signal transmission and reception.
| Parameter | Value |
|---|---|
| Standard | 100Base-FX |
| Data rate | 100 Mbit/s |
| Wavelength | 1300 nm |
| Fiber type | Multimode |
| Supported fiber | 50/125 or 62.5/125 µm |
| Optical connector | Duplex SC |
| Maximum transmission distance | Up to 2 km |
Why Use Fiber Optics?
Standard Ethernet over twisted-pair cabling typically has a maximum link length of approximately 100 m. Fiber optic transmission extends this distance to several kilometers while providing additional benefits.
- Up to 2 km instead of 100 m for Ethernet connectivity.
- Immunity to electromagnetic interference.
- Galvanic isolation between connected sites.
- No induced electrical voltage through the fiber optic link.
- Reliable data transmission between separate buildings and facilities.
- Suitable for industrial environments.
Store-and-Forward Switching
The CS-100C-M30 operates in Store-and-Forward mode. The media converter receives an Ethernet frame, checks it, and then forwards it through the other interface.
This method helps ensure stable data transmission between the copper and fiber optic segments of the network.
Support for Large Ethernet Frames
The specified maximum frame size is 10,240 bytes. This allows the device to be used in networks that employ larger Ethernet frames.
LED Indicators
LED indicators on the enclosure provide quick visual monitoring of media converter operation.
| LED | Function |
|---|---|
| PWR | Device power status |
| TP | Copper Ethernet link status |
| FX | 100Base-FX optical link status |
The indicators make it easy to check whether the device is powered and whether the copper Ethernet and optical links are established and operating correctly.
5 V DC Power Supply
The CS-100C-M30 uses a standard 5 V DC power supply. The power connector size is 5.5/2.1 mm.
Low power consumption of just 0.7–1.5 W makes the media converter easy to integrate into compact network installations.
| Parameter | Value |
|---|---|
| Supply voltage | 5 V DC |
| Power connector | 5.5/2.1 mm DC jack |
| Power consumption | 0.7–1.5 W |
| USB power | Available via a USB-to-DC adapter |
USB Power Option
For mobile or compact installations, the media converter can be powered using a USB-to-DC adapter. This allows the device to receive power from a compatible USB port without requiring a separate AC/DC power adapter.
This option can be useful for temporary systems, maintenance applications, small communications nodes, or installations with a stable USB power source.
Compact Design
One of the key advantages of the CS-100C-M30 is its compact size. The enclosure measures just 62.3 × 42.3 × 22 mm and weighs only 100 g.
This allows the device to be installed:
- in small telecommunications enclosures;
- next to an IP camera;
- in access control systems;
- in industrial cabinets;
- in kiosks and terminals;
- in server and equipment rooms;
- in compact automation systems.
Standard and Industrial Temperature Versions
The CS-100C-M30 is available in versions designed for both standard operating conditions and more demanding temperature environments.
| Version | Temperature range |
|---|---|
| Standard | −10...+55 °C |
| Industrial | −40...+80 °C |
| Storage | −40...+85 °C |
| Humidity | 5–95%, non-condensing |
The industrial version allows the media converter to be used in outdoor cabinets, unheated spaces, transportation systems, and industrial installations, provided that the device is adequately protected from environmental conditions.
