My Telephone Company, cable company, or Internet Service Provider (ISP) is providing me service over a "T1 line".  They terminated this circuit in a telephone cabinet, and I need to bring that circuit back over fiber optic cable to where my T1 router is located in our Server Room.  Can I use the 10/100 or Gigabit Ethernet media converters I have on hand to do this?

The correct connection is always Transmit (Tx) port at one end of the circuit to Receive (Rx) port at the opposite end of the circuit.  Transmit port to Receive port, Receive port to Transmit port.

Not directly.  The standard for 1000Base (Gigabit Ethernet over fiber optic cable) transmission differs from the 100BaseFX Fast Ethernet over fiber optic cable standard in data rate and possibly in the frequency spectrum used to transmit this data.  It is possible to make a connection to the other device using an appropriate media converter.  Please call Signamax's Technical Support experts for a recommendation best suited for your needs at 1-800-446-2377.

No.  The Signamax model 065-1196 series 10/100/1000BaseT/TX to 1000BaseSX or 1000BaseLX media converters use switching technology to convert the 10Base or 100Base packets your 10/100 switch presents to the media converter to the correct framing and format needed to communicate that data over a Gigabit Ethernet fiber (1000BaseSX or 1000BaseLX) connection.  The fiber optic part of the circuit transmits at Gigabit Ethernet speed; the connection from the 10/100 switch will run at the highest speed and duplex mode that the switch can support.  Please note that this means the actual throughput of the circuit will be no greater that that of the lowest speed connected device - in this case, either 10 Megabits per second (Mbps) or 100 Mbps.  However, if a 1000Base capable switch is connected, it will transmit at 1000Base.

Unfortunately, no.  T1 circuits are a completely different type of data transmission that is incompatible with packet-based Ethernet data transmission. T1 media converters are relatively expensive and difficult to obtain quickly, since the market for them is relatively small compared to the market for Ethernet applications.  Signamax does not currently have a T1 media converter product in our line. However, we at Signamax may be able to help you if the T1 connection is to be used for Internet access, private network data, or Voice over Internet Protocol (VoIP) services, rather than standard, non-VoIP telephone service.  The T1 routers available from many manufacturers that are used to connect into a switched Ethernet Local Area Network (LAN) have two connections; one is a connection to the LAN, and the other is a connection to the T1 service provider, commonly called a Wide Area Network (WAN).  Since most T1 routers are administered using the LAN port rather than a local console serial connection that requires close proximity to the administrator, there is no administrative reason to locate the router in the Server Room.  If the router can be co-located with the T1 circuit termination (also known as a Demarcation Point or Demarc Point), the Signamax 065-11xx series of 10/100BaseT/TX to 100BaseFX media converters can be used to connect the router's LAN port over fiber optic cable to the LAN switches, wherever they might be on the premises.
