Installing SFP and XFP Transceivers and GBICs

The 1000BASE-BX bi-directional SFPs (part numbers AA1419069 and 
AA1419070) provide 1000BASE-BX (1310 nm/1490 nm, wavelength, Gigabit 
Ethernet) connectivity over a single fiber (

).

Figure 5   Bi-directional 1000BASE-BX models

As shown in 

, the Tx and Rx paths share the same fiber, at 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 to a mating pair, as shown in 

. 

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 both multimode and single-mode fiber optic cabling.

 describes standards, connectors, cabling, and distance for the Model 

1000BASE-BX SFP.
