RJ-45 Ethernet 10/100/1000 Filtered Interface — JRE LAN-1
Single-channel RJ-45 low-pass interface for 10/100/1000 Ethernet, with all eight lines low-pass filtered and over 80 dB attenuation above 1 GHz.
JRE LAN-1 specifications
- Isolation
- Over 80 dB above 1 GHz
JRE LAN-1 overview
When one gigabit-or-slower Ethernet connection has to cross the shield wall, the JRE LAN-1 keeps the setup direct and easy to specify. I use it to pass the wired link while reducing the cellular, LTE, WiFi, and other RF that can ride along the cable.
- RJ-45 interface for 10/100/1000 Ethernet and other formats using the same connector
- Low-pass response flat below 480 MHz, preserving the intended Ethernet signals
- Rejects cellular-band and higher interference above 700 MHz
- Over 80 dB attenuation above 1 GHz for strong conducted-RF control
- All eight signal lines shielded inside a machined-aluminum housing
- Single-channel interface priced at $435.00 and currently in stock
This is the purpose-built choice for standard Ethernet through gigabit rates. If the link is 10GBASE-T, use the LAN-10G family instead because that data occupies a different frequency range. Include the enclosure model with your quote request so we can confirm the mounting plate fit before specifying the interface.
