Does anyone know a company that makes a SFP that works with Juniper EX switches 
for use with a single strand of single modeĀ fiber? Cisco has the following.. 



1000BASE-BX10-D and 1000BASE-BX10-U SFP for Single-Fiber Bidirectional 
Applications 
The 1000BASE-BX-D and 1000BASE-BX-U SFPs, compatible with the IEEE 802.3ah 
1000BASE-BX10-D and 1000BASE-BX10-U standards, operate on a single strand of 
standard SMF. 
A 1000BASE-BX10-D device is always connected to a 1000BASE-BX10-U device with a 
single strand of standard SMF with an operating transmission range up to 10 km. 
The communication over a single strand of fiber is achieved by separating the 
transmission wavelength of the two devices as depicted in Figure 3: 
1000BASE-BX10-D transmits a 1490-nm channel and receives a 1310-nm signal, 
whereas 1000BASE-BX10-U transmits at a 1310-nm wavelength and receives a 
1490-nm signal. Note in Figure 3 the presence of a wavelength-division 
multiplexing (WDM) splitter integrated into the SFP to split the 1310-nm and 
1490-nm light paths. 


Thanks in Advance
