Description

3G SDI over fiber, 3G SDI Fiber Extender with RS485 control for data

Optical Transmitter Receiver kit -

PN# F-M1SDI-3G-TX/RX
Extend 3G, HD-SDI or SD-SDI digital video signals over single-mode fiber optic cable
Base Model F-M1SDI-3G-TX / RX support single mode fiber up to 20Km and it has ST / PC connector

Thor Fiber ultra compact 3G SDI fiber extender kits are designed to increase the range of digital 3G, SD-SDI or HD-SDI video signals over singlemode fiber optic cable. SDI is normally carried over coax cable on BNC connectors, however the maximum cable distance is limited to around 100 meters. Thor SDI extenders increase the distance to more than 80 miles by using lasers to send data over the fiber cable.

F-M1SDI-3G-TX/RX kit with ST/PC fiber connector, supports single mode fiber up to 20Km

Up to 3G SDI Optical Fiber converters.

It allows the transport of SDI, HD-SDI, and 3G SDI over distances up to 20km using single-mode fiber optic cable with ST/PC Standard

Question and Answers

Question:

As I discussed last week with Cameron and Mark, I'm looking for a much smaller version of our EDFA amplifier (https://thorbroadcast.com/product/20-dbm-edfa-optical-amplifier.html) for use in tactical deployments. I found this item but our Government client now requires products made in the USA.

Here is a description of our application: we are currently sending an A/V feed from our MaximusH265Pro box camera over the air at a distance of 200m using our transmit/receive beam shaping optical front end. I'm using a F-M1SDI-3G-TX to transmit and F-M1SDI-3G-RX to receive. Our link margin should get us to 300m without an EDFA, but we would really like to go out to 500m or greater.

I would also like to see what's possible in terms of increasing the aperture at the receiver end. I have increased the "ease in coupling" our optical front end to the F-M1SDI-3G-RX on the receive end using multimode fiber. This allows me to get our link up and running quickly without noticeable impact on link margin via simple mechanical alignment (tripod), so I was wondering if the alignment process can be further improved with a wider receiver aperture.

Answer:

That won't be an issue. If you have the M1sdi-3G units; the transmit and receive pair; you can check the specs' and see on multimode fiber they work for about 2000ft; but over singlemode fiber the standard units go about 20km.

In none of the situations you mention above are you coming even remotely close to 20km so the standard stock units should be more than capable to handle your current environment.

Unfortunately the distance limitation is not inherently within our unit, but with the choice of fiber you are using. Regardless of how strong we make the optics in the transmitter, the distance limitation residing within the multimode fiber core is the problem area that degredates your signal transmission.

EDFA will not help if you are using multimode fiber.

The right solution would be to use single mode fiber instead of multimode. Then, you will not even need EDFA for 500 meters. Please let me know if this is clear.
