Avaya 1000BASE-LX, SFP AA1419049-E6 用户手册

The 1000BASE-BX bidirectional SFPs (part numbers AA1419069-E6 and AA1419070-E6;
internal part numbers 323243-B and 323244-B) provide gigabit Ethernet connectivity over a
single fiber.

The following figure shows an example of a 1000BASE-BX10 SFP pair. The appearance of
the connector can vary in shape and latch color.

As shown in the previous 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.

You can use 1000BASE-BX SFPs 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 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 following table describes standards, connectors, cabling, and distances for the
1000BASE-BX SFP.
