ABL Corp 1U 24-port BNC 75 ohm female-to-female 19 inch distribution

1U 24-port BNC patch panel

The ABL Corp panel fits a standard 19-inch rack in a single rack unit and provides 24 BNC female-to-female ports for coaxial signal routing. It is built from powder-coated steel and requires no external power source. Installers can mount it directly in a distribution rack and use the labelled ports to organise video or data feeds.

75 ohm to 120 ohm impedance conversion

Each port converts unbalanced 75 ohm coaxial signals to balanced 120 ohm twisted-pair lines, supporting 2 Mbps E1 and 8 Mbps E2 bit rates per ITU G.703. Return loss exceeds the G.703 requirement at 25 dB across 51 to 3072 kHz for the 2 Mbps stream, while isolation voltage is rated at 250 V DC for one minute.

Handles E1 and E2 distribution with 80 dB isolation

The panel comfortably distributes standard E1 and E2 streams in professional video or telecom installations, and the 80 dB inter-port isolation from 5 kHz to 12.672 MHz keeps crosstalk low. It is not suited for applications that require active signal amplification or power-over-coax functionality.
