Q12:
What
is the maximum distance for 100Base-TX/FX multi-mode
Fiber Converter?
In
full duplex mode, the converters can extend fiber distances up to
2Km (Kilo meter).
In half duplex mode, the converters can extend fiber distances up to
412m (meter).

Q11:
What is the maximum distance for a 100Base-TX/FX single-mode
Fiber Converter?
In
full duplex mode, a converter using single mode fiber will extend
distances up to 20Km, 40Km, or 100Km optionally. Therefore, it is
not recommended for a 100Base-TX/FX single mode fiber converter to
run under half-duplex mode with single mode fiber.

|
Q10:
What is the maximum distance for a 10Base-T/FL multi-mode
fiber converter?
A
10Mbps 10Base-FL multi-mode fiber converter can extend distances up
to 2Km regardless of whether half or full-duplex mode is used.
|
|
Q09:
Can I use hub instead of switch to connect with fiber converter?
Yes,
fiber converter can be used with hub or switch.
But
for optimal performance, to fully utilize the fibers long-range
transmission advantage, the 100Base-TX/FX converters should be
deployed together with switches and not hubs. Switches support full
duplex mode while hub not. This allows point-to-point connection of
up to 2Km for multi-mode fiber and up to 100Km for single mode
fiber.

Q08:
Why do we need Gigabit multi-mode SX to single mode LX converters?
Until
this Q&A released, a 10 / 100 LAN switch with a Gigabit module
or Gigabit switch comes with 1000Base-SX gigabit port(s) that will
only support point-to-point connections of up to 280m. A Gigabit
multi-mode SX to single mode LX converter has the potential to
extend this distance to 10Km.
|
|
Q07:
What is the maximum point-to-point transmitting distance for
Gigabit multi-mode SX to
single mode LX converters?
The
maximum point-to-point transmitting distance for Gigabit multi-mode
SX to single mode LX converters is 10Km + 280m = 10,280m.
|
|
Q06:
What are the 1000Base-LX and 1000Base-ZX?
The
1000Base-LX is a Gigabit LX fiber converter that can supports up to
500m if 50/125 microns multimode fibers were to be used, and 10km if
use 9/125 microns single mode fiber. They are available now.
The
1000Base-ZX is a Gigabit long-haul single mode fiber converter that
can support up to 70km if use with 9/125 microns single mode fiber.

Q05:
What is difference of Multi-Mode and Single-Mode fiber cable?
Fiber
cable consists of Core, Cladding, Coating, Strength members and
Jacket.
For
Multi-Mode fiber: Typically 62.5/125 fiber (A core of 62.5 microns
and with cladding of 125 microns)
For
Single-Mode fiber: Typically 8.3/125 fiber (A core of 8.3 microns
and with cladding of 125 microns)
(Note:
micron: millionth of a meter (m)

Q04:
What is the Wavelength of Fiber Cable used?
It
is 1300nm wavelength for both Fast Ethernet (100Mbps) and Gigabit
Ethernet (1000Mbps).
It
is 1550nm wavelength for single mode operation.
|
|
Q03:
What is the MPR and DTE difference?
MPR
is the position to connect Twisted-Pair to a Switch or Hub
DTE
is the position to connect to a workstation, or LAN card (Network
Interface Card).
(DTE
pin-outs is crossover on board already)

|
Q02:
What is the specification of Fiber Cable can be used for Fiber
converter?
50/125,
62.5/125, or 100/140mm for multi-mode
8.3/125,
8.7/125, 9/125 or 10/125mm for single-mode
|
|
Q01:
What is the data transfer rate of Fiber converter?
1000Mbps:
1,488,100 PPS (Packet Per Second)
100Mbps
148,800 PPS
10Mbps
14,880 PPS
