Kojerasia Kathrein ESM 32 21110010

ESM 32 — modular outlet box for CATV/HFC networks providing a modem loop-through and separate TV/radio output. The unit offers broadband operation across the specified ranges and is built with a stable die-cast housing and screw-and-claw fastening suitable for flush mounted boxes with diameter 55–65 mm. Connections are provided as TV IEC connector, Radio IEC socket and Modem F socket. The device is compliant with EN 60728-11 and EN 50083-2 and includes an ingress noise blocking function and a built-in non-removable filter solution to prevent manipulation by subscribers.

Advantages

The Kathrein ESM 32 ensures very high decoupling between the modem and the TV/radio outputs to avoid modem-induced interference with television and radio reception. It provides directional coupler outlet loop-through with a connection loss of 10 dB and broadband signal distribution at the TV and radio outputs. The ingress noise blocking function reduces unwanted interference from subscriber terminals, while the integrated non-pluggable filter design increases system protection against later tampering. The robust die-cast housing and standard mounting fittings enable reliable installation and long-term mechanical stability.

Suitable for

• Interactive CATV/HFC networks requiring a modem loop-through
• Installations needing separate TV, radio and modem outlets in a flush-mounted box (Ø 55–65 mm)
• Residential or commercial signal distribution points where ingress noise blocking and tamper-resistant filtering are required

Key specifications

• Frequency ranges — Modem: 5–1006 MHz; TV: 85–1006 MHz; FM: 85–1006 MHz
• Connection loss (directional coupler outlet): 10 dB
• Standards: EN 60728-11, EN 50083-2
• Housing: die-cast
• Mounting: screw and claw fastening for flush boxes Ø 55–65 mm
• Connections: TV — IEC connector; Radio — IEC socket; Modem — F socket

How to use

Install the ESM 32 into a compatible flush-mounted box (diameter 55–65 mm) using the screw and claw fastening. Connect the incoming coaxial feed to the modem F-socket input and use the directional coupler outlet for loop-through to the modem. Connect TV and radio receivers to the respective IEC connectors. Ensure all connections are tightened and grounded according to local installation rules. The built-in filter and ingress noise blocking functions operate automatically once the unit is correctly installed.

Recommendations

Install the device within compliant CATV/HFC systems and follow EN-standard installation practices. Do not remove or alter the built-in filter to maintain tamper protection and the ingress noise blocking function.
