Warning:
Risk of equipment damage
To prevent damage to the optical receiver, ensure that at least 5 dB of attenuation exists
between the transmit and receive ports.

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.
