CS-1000C — compact Gigabit media converter from 10/100/1000Base-T to 1000Base-X
OPTOKON CS-1000C — a compact Gigabit Ethernet media converter for signal conversion between copper Ethernet 10/100/1000Base-T and a fiber-optic link 1000Base-X. The device enables quick conversion of a standard RJ45 connection to a fiber-optic link and extends the data transmission distance to 2 km over multimode fiber or up to 20 km over single-mode fiber.
CS-1000C is equipped with one RJ45 port and a duplex optical interface SC. The media converter supports both Multimode 50/125 and 62.5/125 µm, and Single Mode 9/125 µm, making it suitable for local fiber-optic networks within a building or campus, as well as inter-building and remote Gigabit connections.
The device supports Auto-Negotiation, Auto MDI/MDIX, Flow Control, Jumbo Frame up to 9K and the Link Fault Pass Through function. This makes CS-1000C more than just a basic media converter: it is a convenient, feature-rich solution for professional Ethernet networks.
Compact dimensions of 50 × 69 × 25 mm and a weight of just 100 g allow the media converter to be installed in small telecommunications enclosures, server rooms, video surveillance systems, industrial cabinets, kiosks, BMS systems, or directly next to end-user network equipment.

Operating principle
The CS-1000C is installed between an Ethernet device with a copper RJ45 interface and a fiber-optic link. A standard Ethernet cable connects to one side of the media converter, while duplex optical fiber connects to the other.
Typical connection diagram:
Ethernet device → RJ45 → CS-1000C → optical fiber → CS-1000C → RJ45 → Ethernet device
This approach allows two Ethernet segments to be connected over a distance significantly greater than the standard 100 m for copper twisted pair.
10/100/1000Base-T Ethernet port
The CS-1000C copper interface supports speeds of 10, 100 and 1000 Mbit/s, allowing both modern Gigabit equipment and older Fast Ethernet devices to be connected.

Single Mode and Multimode in one family
One of the key advantages of the CS-1000C series is its support for both multimode and single-mode optical fiber.
Multimode is recommended for local area networks within buildings, campuses, industrial sites, or data centers where the distance between nodes is relatively short.
Single Mode is suitable for remote sites, inter-building connections, geographically dispersed nodes, video surveillance systems, and other applications requiring a reach of up to 20 km.
Jumbo Frame 9K
CS-1000C supports Jumbo Frame up to 9K. Using larger Ethernet frames can reduce network overhead and improve the efficiency of transferring large volumes of data in a compatible network environment.
This feature is particularly useful for:
- server connections;
- data storage systems;
- large file transfers;
- high-quality video streams;
- industrial and enterprise networks with Jumbo Frame support.
Link Fault Pass Through
Link Fault Pass Through (LFP) — a useful feature for monitoring link integrity. If one network segment loses its connection, fault information is passed to the other side of the media converter.
For example, if the optical fiber breaks, the Ethernet port on the opposite side can also enter the Link Down state. This allows a switch, router, or monitoring system to identify the problem more quickly.
Why LFP is needed
- rapid detection of a fiber-optic link break;
- proper operation of network monitoring systems;
- minimizing situations where the Ethernet Link is active but there is no actual end-to-end connection;
- easier diagnostics of remote network nodes.
Flow Control
CS-1000C allows you to enable or disable Flow Control according to the requirements of the specific network. Flow control helps reduce packet loss during brief periods of congestion and when devices process traffic at different rates.
Store-and-Forward
The media converter operates in Store-and-Forward Switch Mode. The device receives the entire Ethernet frame before forwarding it through another interface.
This approach ensures stable data transmission between copper and fiber media and enables basic Ethernet frame checks before forwarding.
Auto MDI/MDIX
Support for Auto MDI/MDIX simplifies connection to the copper network. The device automatically detects the Ethernet connection type, eliminating the need to choose between a straight-through or crossover cable.
This is especially convenient for maintenance, upgrading legacy networks, and rapid equipment installation on site.
LED indicators
LED indicators allow quick monitoring of the media converter's status without additional diagnostic equipment.
| Indicator | Function |
|---|---|
| PWR | Power status |
| TP LINK/ACT | Copper Ethernet link status and activity |
| 1000 | Gigabit mode indication |
| Fiber LINK/ACT | Fiber link status and activity |
Flexible 5–12 V DC power input
CS-1000C supports a wide input voltage range of 5–12 V DC, simplifying media converter integration into various systems.

|---|---|
| Input voltage | 5–12 V DC |
| Power connector | DC 5.5 × 2.1 mm |
| AC/DC adapter option | 5 V DC / 1 A |
| AC/DC adapter option | 12 V DC / 1 A |
The ability to use a 5 V or 12 V power supply makes integration convenient in telecommunications, video, automation, and other systems with different DC power sources.
Compact form factor
CS-1000C has dimensions of just 50 × 69 × 25 mm and a weight of 100 g. This allows the device to take up minimal space and be installed virtually anywhere in the network.
Typical installation locations:
- small telecommunications enclosures;
- video surveillance cabinets;
- network distribution frames;
- industrial cabinets;
- server rooms;
- BMS systems;
- kiosks and information terminals;
- local network nodes.
