Network transmitter & receiver EASYLAN CKEFFL00 — Silver, supports 10/100/1000/10000 Mbit/s, Cat6a, up to 90 m

EASYLAN CKEFFL00 is a compact network transmitter and receiver in a silver finish, designed for copper Ethernet links using Cat6a cabling. The device supports IEEE networking standards and data rates of 10, 100, 1000 and 10000 Mbit/s, enabling Gigabit and 10G connections over short to medium cable runs. It is intended to extend or bridge wired networks over a maximum transfer distance of up to 90 m when installed over the specified Cat6a cable.

Advantages

The unit provides multi-rate support (10/100/1000/10000 Mbit/s) for compatibility with a wide range of network equipment and automatically negotiates link speed where supported. Its Cat6a-optimized design allows higher throughput and reduced crosstalk compared with lower-category cabling on equivalent runs. Compact silver housing simplifies placement and integration into existing patching areas or equipment racks, and the device is suitable for short to medium distance extensions without the need for fiber conversion.

Suitable for

• Extending or bridging wired Ethernet links within office floors or equipment rooms
• Connecting switches, routers or servers over Cat6a copper cabling up to 90 m
• Short-range 10G or Gigabit uplink segments where fiber is not available
• Temporary network setups, testing environments, or lab installations

Key specifications

• Supported data rates: 10 / 100 / 1000 / 10000 Mbit/s
• Cabling type: Cat6a (copper twisted pair)
• Maximum recommended transfer distance: up to 90 m over Cat6a
• Connector type: standard RJ-45 Ethernet ports (for copper links)
• Housing color: silver

How to use

Install the EASYLAN CKEFFL00 between two compatible Ethernet devices using Cat6a cabling and standard RJ-45 terminations. Verify link negotiation and speed on connected network equipment; the device supports automatic negotiation for the listed data rates. Ensure cable runs do not exceed the specified maximum distance of 90 m for reliable 10G operation. Place the unit in a well-ventilated area and route cables to avoid sharp bends or excessive strain on connectors.

Usage recommendations

For optimal 10G performance, use certified Cat6a cabling and maintain the maximum recommended distance. Confirm that connected switches and network interfaces support the desired link speed, and check link LEDs or management interfaces to verify stable operation. If longer distances or optical isolation are required, consider using fiber-based solutions instead of copper extensions.
