Need fiber optic input jack for Onkyo TX-DS575

Your receiver appears to have a digital optical input, so no converter would be needed, just an optical fiber cable (TOSLINK) between the two optical ports. However, the manual for your receiver states that several functions don't work unless there is also an analog connection. If you must have those, you can use an HDMI audio extractor. You may also need an adapter cable to convert 3.5 mm stereo audio to a pair of RCA phono plugs to make the analog connection.

The crucial difference between copper cable and fiber optics is that copper cable transmits signal in the form of electrical pulses while fiber optics possess signal transmission in the form of light pulses. ... As against fiber optics is formed by single or multiple strands of glass fiber.

100BaeFX to 100BaseTx media converter. ST to SC cable.

SCA connector goes to the RX port in media converter.

STA connector goes to the TX jack on network adapter.

SC male B to TX port on media converter.

ST male B connector to the RX jack on network adapter.

Connect media converter to network with Cat5e cable which uses RJ-45 connectors.

HD Video FROM your TV???? Video goes TO the TV and gets there either via direct tuning of an HD air station or from a Cable?SAT box, BluRay player... The unidentified TV's manual should cover that.

The Onkyo's manual covers most of the rest.

My $.02...

NO signal ever benefits from multiple connections or 'hops' and it gets expensive zig-zagging a signal all over the room. K-I-S-S is the word of the day. Run the BEST version of any signal directly from its source to the BEST electronics that will present it to you for consumption. The separation of audio and video inputs and outputs on a device is what allows and ENCOURAGES the routing of each signal to the BEST electronics that can process it. Example: your TV does not have the best speakers in the room so why send it any high-end audio?

If the sound actually comes from an external source treat that source like any other hi-end audio component and attach its highest quality audio directly to the receiver according to ITS manual. The separation of audio and video inputs and outputs on a device is what allows and encourages the direction of each signal to the BEST electronics that can process it.

As far as the TV audio goes... unless it is the primary source of the audio (tuned through its own antenna and available no where else) why don't you just run the actual primary source's (cable/sat, whatever) best digital audio straight to the Onkyo and skip the middleman that adds nothing to it but expensive unnecessary cable hops.

I'd also run each video sources absolute best video straight to the TV for the same reason.

Hi troy my names Josh i would be glad to be able to help you with your setup. First things first some people have a preference with they way they like things and for one do myself. I set up and intstalled my home theatre. I have receiver much like yours. On the back of your reciever you should have multiple inputs of coarse some for sound some for video. Your sound inputs would include digital optical, digital coax, standard analog which of coarse is the red and white RCA inputs and then a multi in which i doubt you have. So lets start simple If you have satalite or some form of cable i would assume you have your reciever box feeding a signal to your tv and the same for your DVD. I would recommend for your sat. that you connect your picture and sound strait to the tv rather it be component video or s video or standard video source or connect then for your sound strait analog to your tv thats just Red and White RCAs which will give you your sound to your tv. Repeat the same for your DVD depending on the kind of inputs and number of inputs you have on your TV. Now for the sound to your reciever. I ran digital sound from both my DVD and my Satilite to the reciever which means on the back of your recievers providing you have a similar configuration you would look for a plug on your dvd player that says optical thats your digital to run sound to your onkyo and the same for your sat or cable if you have a box look for either digital optical or a single digtal coax output that will also be ran to the onkyo for sound. You should only have two cables running to the onkyo one fiber optic from your dvd to the onkyo and one digital coax or fiber optic to your onkyo depending on the number of those inputs you have on the back of the onkyo you can run it how ever you want.

Make sure your DVD setting is looking at the right audio inputs. Usually there is a menu option or a button to toggle from analog or digital input. Usually when no-sound but video ok, you have the wrong input-type selected. If you are using 2 RCS's (red/white) then you want ANALOG input mode. If you are usung a single RCA (orange) or a fiber optic input for audio, you want DIGITAL input selected. If digital os selected, make sure you plug into the correct digital input to hear. If it does not work at first, mofe the jack/fiber around into the different inputs untill you hear sound, then you will know which port is associated with the DVD setting. Unless it is self evident feom the menu.

I tried to answer this for you yesterday but FixYa didn't put it through I guess. I'll try again.

That device is a "Industrial Media Converter". It is for converting a 100BASE-TX LAN cable into a 100BASE-F fiber optic cable for long-range networking. (2km) There are two ways to use it.

One:
Get two and convert LAN to fiber, then back to LAN.

Two:
Use it to tap into an existing fiber network, like fiber optic Internet.

For the first case; you will need some "Duplex" "multi-mode" fiber optic cable ($1.10 a meter) and an other one of those devices ($50~$300).

For the second case you will also need some fiber optic cable and you will need a network to tap in to. Of course you will need to clear everything with the company that owns that network before you can do any thing. And that’s assuming that they even use the same system level protocols.

To directly answer your question:

1: Hook the 100BASE-TX LAN port up to a PC, Hub, or a switch.

2: Hook up TWO multi-mode fiber optic cables to the device using CT style connecters. Hook one to the TX and one to the RX connectors on the unit.

3: Run the cable how you see fit.

4: Hook the other end up to the interfacing device. Be it joining it to an other cable in an existing network, or to another of those devices.

Note: The TX cable of one device goes to the RX of the other and visa-versa.

P.S. I also have one exactly like that one that I’m trying to find a use for.

Make sure that the place it is plugged into the TV is an output and not an input for the fiber optic cable, and the place it is plugged into the Onkyo is an input and an output for the fiber optic cable. This can be connected backwards very easy. Then you want to make sure that the Onkyo is properly set on the right function to listen to the TV. Check your owners manual on how to set up the optical input and have it assigned to the function you are trying to use. Sometimes these type of receivers have an input mode button that you can set to "optical" or "analog" or "digital" or "auto". Try changing those settings after you make sure the TV optical is an "OUTPUT" and the optical on the Onkyo is a "INPUT".

After you have these thing set right you should be able to listen to it like this.

I hope this helps, if you need more help just reply back on this post, but please give more detail about the connectors and on the TV and the Onkyo, and about the digital input settings on the Onkyo. It would also help to know the model numbers of both the TV and the receiver. There is no way to check out what each of your devices are capable of doing without knowing the model numbers to look up the specs.

Thanks,

Dave

If you are using digital optical or digital coaial and getting sound on regular 5.1 dvd's your conections are fine. With sony players you have to get into the setup menu and turn DTS "ON" in the audio sub-menu. For some reason they default it to "off".
