The StarTech 2-to-1 RJ45 Splitter Adapter supports 10/100 networking speeds and delivers two networking signals using a single Ethernet cable. This setup requires you to have two 2-to-1 RJ45 Splitter adapters. It takes the signal coming from two cables and delivers the data through a single Cat 5 or 5e cable to the second optional adapter, which separates the signal back to two connections. This feature eliminates the need to run two cables throughout the home or workplace to connect a computer and Smart TV to the router. In addition, the adapter comes with two Ethernet female jacks and an integrated cable with an Ethernet male connector.

Related Questions and Answers

Q: 1. Can I use this adapter to connect my Dell Precision laptop with Thunderbolt 3 to thunderbolt 2 Black Magic Ultra studio express capture card with no issues? I will be testing this, just wondering if anyone knows the answer.

A: I ordered the StarTech thunderbolt adapter to connect my Motu 1248 audio interface (which uses thunderbolt 2) to my Dell XPS thunderbolt 3 port. This device has worked flawlessly ever since I purchased it. The Motu 1248 is a very advanced and complicated interface, so my thinking is if it works for the Motu, it should work for just about everything.

Q: 2. Will this device work with a Zerolemon Extended Battery Case or with any other Extended Battery Case when the 3.5mm headset is plugged into it and connected to the Extended Battery Case? These Extended Battery Cases have a USB C port where the device can be plugged into the Extended Battery Case... But when I tried other brands, they do not work.

A: This would heavily depend on the specific case being used. Many have very different sizing. Please check the dimensions of the case that you have and compare it with the StarTech Headset Adapter.

Q: 3. Does this cable come with headphone & microphone labels ?

A: YES! They are labeled with a Headset symbol and a Microphone symbol on the molded outer part of each of the designated receptacle. They are on the small side and are black on black, being molded, and thus not very visible; they are there.

Q: 4. Will this work with a fujifilm x100v camera? I want to record and monitor audio using a Rhode mic and Senal headphones. I have an adapter to plug the StarTech into the camera's audio mic port.

A: No, the StarTech Headset Adapter will not work as desired with the FUJIFILM X100V Digital Camera. This adapter works with a TRRS input/output connection that is capable of sending signal in both directions simultaneously, commonly found on smartphone and some computer headset connections. The 2.5mm microphone input connection on the X100V is an input only, and will not also send output signal to be monitored via headphones. It is suggested to use the microphone input and headphone output connections of the X100V independently in this scenario.

Q: 5. If this adapter most likely will NOT work on PCs and Chromebooks because of the switching for the Apple products (CTIA standard), does B&H carry one that does work on PC's and Chromebooks with OMTP standard? Trying to get my old headsets to work on these devices. I can plug in 1 plug at a time, mic or headphone jack, but that makes me do a lot of switching. THANKS for your assistance!

A: This adaptor was specifically purchased to connect Turtle Beach gaming headset to a Dell (Windows 8) PC laptop. I did not realize when we bought the Dell that they had gone to the single integrated plug. The adaptor has worked flawlessly since then - kids play some MMO thing on line.

Q: 6. can i use it to connect my antalope orion+ (thunderbolt) to usb c port on my asus motherboard?

A: This would fully depend on the Asus Motherboard. Note that not all USB-C ports support Thunderbolt 3. If yours does, this StarTech Thunderbolt 3 to Thunderbolt Adapter will be compatible.

Q: 7. will this work with with a blue yeti mic

A: Yes, this is compatible with the Blue Yeti microphone.

Q: 8. Will this allow the Seagate HDD//8TB to connect to my 2012 macbook pro?

A: This adapter is currently thunderbolt 3 to thunderbolt 2/1 connection only and is mainly used on PC to connect older thunderbolt hard drives. No macs currently support thunderbolt 3. I managed to create a 10Gb network connection between a PC and a Mac Pro using this adapter.

Q: 9. Would this work to connect a shotgun mic to an android smartphone, and at the same time monitor it with headphones?

A: The StarTech Headset Adapter will turn a 3.5mm audio output port into two distinct ports – one 3.5mm headphone jack and one 3.5mm microphone port, so if your shotgun mic and your headphones have a 3.5 mm input this will work fine.

Q: 10. Will this work with Toshiba KIRA laptop or a Samsung Chromebook XE303C12? I bought some adapters similar to this (should have come to you first!) and they work on my iPad but not on these devices. Maybe something to do with the 3 lines and how they are setup? THANKS! LOVE your site!

A: I bought it to use with the headphone that has built in microphone but it did not work with my laptop Lenovo ThinkPad. I returned it.
