opto1394 IEEE1394/Firewire signals 
This system is used for the optical transmission of IEEE1394/Firewire-signals and can transmit data rates of up to 400 Mbit/s (800 Mbit/s at 1394b). The transmitter system consists of two similar transceivers supplied by batteries and a duplex-62,5/125µm-multimode optical cable. Due to its insensitivity against strong electromagnetic fields the opto1394 is fit for tests of electromagnetic compatibility in EMC-test chambers, TEM-cells, and striplines. The system can also be used for the fail-proof transmission of signals across long distances.

optoLAN – 100 MBit per second 

The optoLAN system can be used for the optical transmission of Ethernet (LAN-) signals with a data rate of up to 100Mbit/s (100BaseT). 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. Due to its insensitivity to strong electromagnetic fields above the specified transmission range the system is fit for tests of electromagnetic compatibility in EMC-test chambers, TEM-cells, and striplines.

optoLAN-Gb – 1 GBit/s 

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 simplex-62,5/125µm-multimode optical cable. The Ethernet connectors are custom-made. Due to its insensitivity to strong electromagnetic fields above the specified transmission range the system is fit for tests of electromagnetic compatibility in EMC-test chambers, TEM-cells, and striplines.

optoRS485 

The optoRS485 system can be used for the optical transmission of RS485-signals up to a data rate of 1 Mbit/s. It can be used to transmit RS485-signals over long distances or to handle ground potential problems. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests.

optoTTL 

Optical transmitter for up to 16 digital signals: optoTTL The optoTTL is used for the optical transmission of digital signals. Up to 16 digital signals with a sampling rate of 40 MS/s (each channel) can be transmitted. The system consists of a transmitter supplied by batteries, a simplex-62,5/125µm-multimode optical cable, and a receiver – which has integrated batteries as well. Due to its insensitivity to strong electromagnetic fields above the specified transmission range the system is fit for tests of electromagnetic compatibility in EMC-test chambers, TEM-cells, and striplines.

Product	Input	Output
OptoTTL_5_3_u	2 ranges can be selected: 3.3V and 5V	2 ranges can be selected: 3.3V and 5V
OptoTTL_12_5_u	2 ranges can be selected: 12V and 5V	0/5V
OptoTTL_b-12	0/12V	0/12V

 

The optoTTL-b system can be used for the bidirectional optical transmission of digital signals. It can also be used to transmit digital signals over long distances or to handle ground potential problems.

To ensure that the TTL Configuration is correct, the following questions must be answered:
1. Uni or bidirectional?

2. How many channels per direction?

3. BNC or SUB-D requested?

4. What voltage levels?

5. What bitrate?

6. If deviating per channel, list all channels

optoLAN – option M12 

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.

 

optoUSB2.0 

The optoUSB-2.0 system can be used for the optical transmission of USB-signals up to a data rate of 480 Mbit/s according to USB2.0. It can be used to transmit USB-signals over long distances or to handle ground potential problems. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests.

optoUSB2.0-RBDIR 

As an alternative to the USB-A/B connectors we offer HSD connectors for the automotive use which have a better RF performance concerning emission and immunity.

For this, we have different connector cables available as shown below:

• Cable with Rosenberger HSD-plugs/USB-A-plugs and HSD-plugs/USB-B-plugs

• Cable with Rosenberger HSD-plugs/USB-A-plugs/ bzw. HSD-plugs/USB-A-female plug

• Setup with description

 

Background
Both “USB” and “LAN” interfaces are consumer electronic interfaces, so they are not automotive grade.
This means, that the plug being used for LAN (RJ45) and USB (e.g. Type A or B) can not warrant an automotive level emissions or immunity.
mk-messtechnik designed the optoUSB2.0-RBDIR, with an automotive grade Rosenberger HSD plug integrated and the optoLAN-GB with an M12 industry standard plug.
Both plugs the best shielding available for these high data rates. Still, the opposite side (DUT) has the standard plug integrated. What this means is that the emissions/immunity of the total link is dependent on the quality of the DUT connector and the mk-messtechnik devices add as low as possible to the test.

 

optoUSB3.0 

The optoUSB-3.0 system can be used for the optical transmission of USB-signals up to a data rate of 5Gbit/s according to USB3.0 standard. It can be used to transmit USBsignals over long distances (up to 50m) or to handle ground potential problems. With the optical transmission and the shielded case, the system is well equipped for EMI and EME tests.
