1000BASE-BX bidirectional SFP transceivers
The 1000BASE-BX bidirectional DDI SFP transceivers provides gigabit Ethernet connectivity over a
single fiber.
Warning:
Risk of equipment damage
For the 40 km transceivers only. Connect the 1000BASE-BX SFP transceiver using a single
mode fiber with at least 6 dB of attenuation. Damage can result if insufficient attenuation is
provided or if the same 1000BASE-BX SFP transceivers are connected.
In the following figure, the transmit (Tx) and receive (Rx) paths share the same fiber by using two
different wavelengths. One model transmits at 1310 nm and receives at 1490 nm, while the mating
model transmits at 1490 nm and receives at 1310 nm. You can only connect a mating pair.
The long wavelength optical transceivers used in these models provide variable distance ranges
using single mode fiber optic cabling.
You can use 1000BASE-BX SFP transceivers to double the number of your fiber links. For example,
if you install 20 fiber pairs with 20 conventional ports connected, you can use 1000BASE-BX SFP
transceivers to expand to 40 ports, using the same fiber.
The following table provides the reach and part numbers for each of the mating pairs.
