Fiber-optic Links & Cameras

opto, Fiber-optic, Automotive Link Overview

Discontinued - See dAV-Cr-HD 30x digital Camera

The dAV-Cr-HD-mini camera can be used for the optical and acoustical monitoring of devices under test during EMC measurements. It has an integrated mono microphone and can be remote controlled via fiber from the receiver in the control room. Because of its miniature size and the HD-resolution, high quality DUT surveillance can be done at locations with limited space, e.g. GTEM cells, cars, ... With the optical transmission and the shielded case, the camera is well equipped for EMI and EME tests. No PC needed for display!

The extra small camera dAV-Cr-HD-µ can be used for the optical monitoring of devices under test during EMC measurements. It has especially been developed for restricted space applications (dimensions approx. 30 x 30 x 110mm) and can be remote-controlled from the control room (digital zoom, integrated short-range LED and so on).

The infrared camera opto-LWIR was developed specifically for EMC tests. In high field strengths with directional antennas (fire protection!), an overload of the DUT or the absorbers can be detected early.

The dAV series includes not only the digital, optical transmission of camera signals (dAV-C), it can also transmit analog audio and/or video signals uni- or bidirectionally. Fields of application are e.g. the acoustical monitoring of engine speed or surveillance of an audio or video system in immunity tests. The main unit dAV is thus equipped with different options. The dimensions of the housing depends on the options chosen.

The Analog transmission links of the „U-series“ can be used to transmit analog or digital signals 1:1. They can be used to optically transmit signals from inside to the outside of the ALC or to transmit a stimulus inside the chamber (with optional output filter).

The optoLAN-BCM89811 system can be used for the optical transmission of automotive ethernet signals with Broadcom© BCM89811© and other 100BaseT1 chipsets.  There are two setups available, T1 to T1 (standard) or T1 to Tx (with integrated media converter => optoLAN-BCM89811 -MC), see separate setup document.  The standard connector is Rosenberger HSD (Z-coded). 

The optoLAN-100-MAX system can be used for the optical transmission of Ethernet (LAN-) signals with a data rate of up to 100Mbit/s (100BaseTx). The two identical transceivers are supplied by internal batteries and connected with an optical fiber. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests. The device is not downward compatible to 10BaseT. If you need this option you can get the optoLAN-Gb.

This optical device is used for the bidirectional optical transmission of ethernet signals with a transmission rate of 1 GBit/s. It is downward compatible to 100BaseT and 10BaseT (automatically detected). The system consists of two identical transceivers supplied by batteries and a duplex 62.5/125µm-multimode optical cable.

A new type of connector is available now: The M12 connector (MMT471A315, counterpart MNF881A315-0001) by Metz Connect was integrated into our optical transmitter for Ethernet signals optoLAN, as well as optoLAN-Gb. Therefore, these devices are even fitter for tests of electromagnetic compatibility.

LVDS (Low-voltage differential signaling) systems are tailored to each individual application. We work closely without clients to understand and develop a perfect fit product that will have no issues once implemented. We have the most experience in the industry developing and delivering such systems. See below examples of what we have offered.

The optoLAN-TJA1100-MAX system can be used for the optical transmission of automotive ethernet signals with NXP© TJA1100© chipset (unshielded twisted pair UTP ethernet). The system can be set up with two identical transceivers or one side automotive ethernet and the other 100BaseT. With this setup, the link can be used as a media converter. The devices are supplied by internal batteries and connected with an optical fiber. The standard connector is a 4 pole Rosenberger HSD.
