Description

Transport of 8 Ch 3G-SDI Over Fiber F-8SDI-3G-TXRX-RM

Thor Fiber uncompressed 3G-CWDM part number F-8SDI-3G-TxRx-RM come in a kit (Tx & Rx) and are standard configuration Fiber Optic Transmitter and Receivers for Serial Digital signals up to 3G-SDI running at 3.0 Gbps. This system can be ordered with any standard CWDM optics package, and internal passives are available by request.  This is a 8 Channel system based on a standard 40km platform.  No configuration or management is needed, as the system automatically adjusts to any input signal type regardless of bit rate or protocol.  Easy to read LED indicators for Input Signal Detect and optical link are present for all channels. Units come standard with ST/PC fiber connectors and a 1RU 19" rackmount form factor to keep your rack clean. Simplified easy to use plug and play units mean that anyone can deploy these in no time. Commercial grade intricate parts means these will work for years without hassle, backed by Thor Fiber's 2 year warranty and free tech support means a stress free guarantee. 

Thor part number F-xSDI-Tx/Rx designates a fiber optic transmitter or receiver used to transport serialized digital signals up to 3.0 Gbps. Any channel configuration up to 16 channels per fiber can be designated by value "x". Units can be configured to transport any number of SDI channels in either direction up to a total of 16 per fiber. For even higher densities, DWDM systems are available by request. Thor uses high quality DFB lasers for maximum reliability and distance, with off the shelf models functioning up to 50km when used with single mode fiber. F-SDI systems will transport any digital signal from 1 Mbps to 3.0 Gbps independent of protocol or standard. These systems can be used for anything from 3G-SDI (SMPTE 424M) to multi rate DVB-ASI down to single program at low bit rates.  F-SDI units incorporate industry standard internal CWDM modules for compatibility with similar systems from other manufacturers, such as Python™ systems. This standardization allows Thor F-SDI equipment to be used in conjunction with other commercial off the shelf transmitters or receivers from other vendors, including Python™ series equipment. All outputs are automatically re clocked to eliminate problems with jitter and to allow for long cable runs out of the receiver. Applications range from live broadcast and Electronic News Gathering to government and scientific research applications. Contact a Thor Sales Representative today for more information on system design and equipment compatibility.

Question and Answers

Answer:
We have a lot of 3G SDI products to choose. Every products on this page is 3G-SDI, we also have single channel compact throwdown kits available as well. https://thorbroadcast.com/products/sdi-sd-hd-3g-with-cwdm Please let me know how many 3G-SDI signals you want to transmit over a single fiber and we'll quote you on it right away.

Answer:
I have my suspicions of what it is.To prove it I suggest getting 2 units for attempting to find the resolution.  We have 2 different technologies for multiplexing SDI and other signals. Inexpensive TDM, we use only one laser, but it has limitations. F-4MSDI-TX/RX 4 ch SDI over the single fiber - $2495 for TX/RX kit https://thorbroadcast.com/product/4-sdi-hdsdi-over-1-fiber-mini-extender.html   CWDM -Optical multiplexing, we can multiplex anything on the separate optical wavelengths. F-4SDI-3GTX/RX  4 ch SDI over the single-fiber  -CWDM https://thorbroadcast.com/product/4-ch-sd-hd-3g-sdi-over-single-fiber-cwdm-uncompressed-rack-mountable.html but we have currently only have 8ch in stock: (i will send you 8ch for checking) https://thorbroadcast.com/product/8-ch-sd-hd-3g-sdi-over-single-fiber-cwdm-uncompressed-rack-mountable.html   if you want to try it, please send us a PO and CC for holding, and we will be glad to send you a unit for testing and approval Please also take a look at these 1-4 HDMI or SDI encoder/ modulators with IPTV out:

https://thorbroadcast.com/product/4-hdmi-component-hd-to-coax-and-iptv-hd-8230.html https://thorbroadcast.com/product/1-4-sdi-to-qam-modulators-and-iptv-streaming-encoders.html

Answer:

Yes our devices is transparent and can send any SDI signal over fiber up to 3GSDI

Within this standard, there are three formats known as Level A, Level B Dual Link (B-DL) and Level B Dual Stream (B-DS). The Level A format is the direct mapping of uncompressed 1080p (up to 60 fps) video into a the serial digital interface at the nominal 3 Gbit/s. The Level B-DL the format is the mapping of dual-link HD-SDI/SMPTE 372M (i.e.: 1080p up to 60 fps) in a single serial digital interface at the nominal 3 Gbit/s. The Level B-DS format is the dual-stream carriage of two independent HD-SDI/SMPTE 292M signals (720p up to 60 fps or 1080i/1080p up to 30 fps) in a single serial digital interface at the nominal 3 Gbit/s  

Answer:

Your best bet is to go with the first unit you mentioned; those are very popular, very reliable and a very good price. 

F-8SDI-3G-TX/RX-RM kits 

Answer:
We have only 8 slots available on 1U device, We can do that on 2 or 3 fiber What is the distance between those 2 locations ? This is the most economical way over 3 fibers : 1 Unit 8SDI TX and 8 SDI RX ( one fiber ) 2 Unit 4SDI TX + 4SDI RX, and 4SDI RX + 4 SDI TX  ( secound fiber) 3  1 Gigabit Ethernet over single fiber  ( third fiber)   We could do it using 2 fibers only, but it is more comlex.     This is the link to the F-SUPERMUX-8 , universal multiplication platform. https://thorbroadcast.com/product/1-8-channel-flexible-hd-sdi-analog-video-audio-rs-data-etherent-8230.html F-SUPERMUX-8  

Answer:

The F-8MSDI-TX/RX can support HD-SDI up to 1080i/60, but we can not do 3GDI on it. We can add 2 Bi-directional Audio card but it will take embedded audio for the first 2 SDI inputs https://thorbroadcast.com/product/8-sdi-hdsdi-over-1-fiber-optical-transmission-multiplexer.html The F-8MSDI-ET-TX/RX is a 8 HDSDI + 10/100 Ethernet We can add 2 Bi-directional Audio card but it will take embedded audio for the first 2 SDI inputs https://thorbroadcast.com/product/8-sd-hd-sdi-ethernet-over-single-fiber-transmission-kit.html If you require 3G-SDI then we need to use CWDM mux. F-8SDI-3G-TX/RX-RM https://thorbroadcast.com/product/8-ch-sd-hd-3g-sdi-over-single-fiber-cwdm-uncompressed-rack-mountable.html Or The F-SUPERMUX-8 , this unit can mux any 8 signals We can not add Bidirectional Audio and Gbe both but the total can not exide 8 , so 2 x for Bidirectional Audio, 1 for Gig ET and 5 for 3G SDI https://thorbroadcast.com/product/1-8-channel-flexible-hd-sdi-analog-video-audio-rs-data-etherent-8230.html If the price matters, I would recommend going with 8 3G SDI F-8SDI-3G-TX/RX-RM, and external GIG ET and Audio on the separate devices and separate fibers.

Answer:
  We do have solutions for both of those things, but not in one device.  So our solution would require you to purchase two different sets over 2 fibers.  Here are the links:   For SDI we have two options; up to HD-SDI and another for up to 3G-SDI https://thorbroadcast.com/product/1-sdi-hdsdi-over-fiber-mini-extender.html https://thorbroadcast.com/product/1-channel-sd-hd-3g-sdi-fiber-extender-1080p-60hz.html   For Gen Lock we have lots of customers use this product.  https://thorbroadcast.com/product/1-cvbs-video-only-over-fiber-tx-rx-kit.html   So if you don't mind using 2 sets over 2 fibers, then this will work out  great for you.  Let me know if you need a formal quote. 

Answer:

he F-6 SDI-3G-TX supports SDI up to 3G SDI 1080p/59.94/60hz,

it uses 8 separate independent circuits and lasers to convert electrical SDI signals into optical signals and back to electrical signals on the receiving side. The 8 optical signals are passively muxed and demuxed using CWDM. The circuits are completely independent and fully transparent, so they work as a gateway. If you need a synchronized signal, this device will not be able to sync all the signals as they are independent of each other. The only way to achieve synchronization is by using an external synchronization.  

Answer:
Those CWDM units we make are of the highest quality, both in parts, boards, and lasers we put in them. NASA uses them for launches and they're in every single NHL arena, plus hundreds of other places.  Not once have we ever received a complaint about them.  The CWDM models are 100% completely uncompressed. The raw video is literally converted to light and then back to copper, the signal data is untouched.    I can't say the same about models we make with TDM, which do compress the signal via time like the F-M8SDI-TxRx.    Those CWDM models should work perfect for the client. We have them in stock.  Also tell them we have a 30 day return policy, so if they don't like them, return them. However, that's never happened before either; I think they're some of the best performing models we make and your client should buy them right this second.   

Answer:
Well there is plenty of information on our website about it.  I also attached the quick config guide that shows all the inputs are flowing to all the outputs.      The simpler explanation is these models for 3G-SDI are CWDM; which means every input has it's own optical laser, which then goes through a CWDM multiplexer that converts it for transport over glass.  The particular mux is what creates 8 in 8 out on both ends; otherwise you would need specific Muxes for 6 up 2 down or 4 up and 4 down.  So technically it's impossible just because of the mux that comes inside the unit.        Let me know if you need something more scientific, I could ask someone in the lab to make up a drawing if that'll help, but it'll be similar to the one on the website. 

Our product, the Thor Fiber F-8SDI-3G-CWDM-TX/RX, is a UNIDIRECTIONAL :

8-channel SDI over fiber transmitter (F-8SDI-3G-CWDM-TX)

and an  8-channel 3G SDI receiver (F-8SDI-3G-CWDM-RX).

The transmitter (TX) contains 8 individual CWDM lasers and functions as an 8 x SDI electrical-to-optical converter. Each of the 8 channels is converted to a unique optical wavelength using modulated light. The transmitter (TX) does not have any optical detectors for optical-to-electrical conversion.

On the other hand, the receiver (RX) is equipped with 8 individual photodetectors, allowing it to detect the 8 unique optical wavelengths generated by the transmitter and convert them back into 3G SDI electrical signals. The receiver (RX) does not contain any lasers, which means it cannot send any electrical or optical signal back to the transmitter.

Based on the technology used, we affirm that it is physically impossible for the receiver to send any signal back to the transmitter. The system only allows for transmission from the transmitter to the receiver, making this unit a "fiber break" secure converter suitable for military or government use.

 

Answer:
Unfortunately, we do not have such a product, and I do not believe this product exists on the market.  We only have a 1-to-1 HDMI over fiber set available, so you would need 6 TX/RX kits over 6 fibers. F-HDMI-TX/RX https://thorbroadcast.com/product/hdmi-fiber-extender-with-ir-1.html   If you have only one fiber , you consul convert HDMI to SDI and use our 8ch SDI over 1 fiber TX/RX kit H-HDMI-SDI https://thorbroadcast.com/product/hdmi-to-3g-hd-sd-sdi-converter.html F-M8SDI-TxRx  up to 1080i/60 https://thorbroadcast.com/product/8-sdi-hdsdi-over-1-fiber-optical-transmission-multiplexer.html F-8SDI-3G-LOOP-TX/RX up to 3G SDI 1080p/60 https://thorbroadcast.com/product/8-ch-sd-hd-3g-sdi-over-single-fiber-with-loop-outputs.html
