1000BASE-BX40 bidirectional SFP specifications
The 1000BASE-BX bidirectional SFPs (part numbers AA1419076-E6 and AA1419077-E6)
provide gigabit Ethernet connectivity over a single fiber.
The transmit and receive 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.
You can use 1000BASE-BX SFPs to double the number of your fiber links. For example, if you
have 20 installed fiber pairs with 20 conventional ports connected, you can use 1000BASE-
BX SFPs to expand to 40 ports, using the same fiber.
The long wavelength optical transceivers used in these models provide variable distance
ranges using single mode fiber optic cabling.
The 1000BASE-BX SFPs (part numbers AA1419076-E6 and AA1419077-E6) can attain a
reach of up to 40 km.
The following table describes standards, connectors, cabling, and distances for the
1000BASE-BX SFP.
Warning:
Risk of equipment damage
Connect 1000BASE-BX SFP AA1419076-E6 to 1000BASE-BX SFP AA1419077-E6 using
a single mode fiber with at least 6 dB of attenuation. Damage can result if insufficient
attenuation is provided or if the same 1000-BASE-BX SFPs are connected.
