I'm using a 10/100/1000 BASE-T fiber transceiver.

What does this mean?

  • $\begingroup$ Hi Rachael, welcome to engineering.SE. Your question is rather vague to anyone who hasn't worked with this specific component. Can you please add some more context to your question? A link to the product you are talking about would be particularly helpful. $\endgroup$ Jun 1 '15 at 20:15
  • $\begingroup$ Are you asking about how the different transmission speeds might affect the technology used, or are you just looking for megabits/sec? And it shouldn't be "-T" if it is fiber, right? $\endgroup$

The 10/100/1000 refers to the transmission rate in megabits per second
= millions of bits per second.
Also may be shown as Mbps or Mb/s.

1000 Mb/s is a data rate typically achieved by modern LAN interfaces.

10 and 100 mb/s are the maximum rates achieved by older standards. A 10/100/1000 label is indicating that the device operates at the 1000 Mb/s rate where it is interfacing with equally capable equipment, but is also able to work at the 10 or 100 Mb/s rate and standards when the equipment it is interworking with is limited to those rates.

As hazzey notes, Base-T does not apply to fibre based equipment. It is a designation indicating that twisted pair is used as the transmission medium.
The original "Ethernet" LAN interface (now part of IEEE 802.3-xxx) used coaxial cable and operated at 10 Mb/s. When twisted pair interfaced alternatives were introduced, the name BASE-T was introduced for twisted pair rather than coaxial cable interconnected equipment. 10 Base-T was used to designate 10 Mb/s twisted pair equipment.
"Just to confuse" designations 10Base5 and 10Base2 were designations relating to thin-coax 10 Mb/s Ethernet in the 1980s.

Wikipedia - Gigabit Ethernet - nominally re 1000 Mb/s systems but covers the historical development.

Ethernet Fibre and twisted pair interfaces exist but that is not what you are dealing with.
