Nortel Networks 1000BASE-SX - Manual (Page 60)

60 SFP specifications
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 following table describes standards, connectors, cabling, and distances
for the 1000BASE-BX SFP.
CAUTION
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.
