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

1000BASE-BX DDI SFP specifications
The 1000BASE-BX bidirectional SFPs provide gigabit Ethernet connectivity over a single
fiber.
Figure 2: 1000BASE-BX
As shown in the preceding 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 following table provides the part numbers for mating pairs.
