Gigabit Fiber Optical Characteristics
The Uplink/Expansion Module on the BayStack 350 switch supports
1000BASE-X (Gigabit Ethernet) MDAs. This appendix describes the optical
characteristics of the 1000BASE-X MDAs. See Appendix C, “Media Dependent
Adapters,” for more information about MDAs.
1000BASE-SX Models
The 450-1SX and 450-1SR MDAs provide 1000BASE-SX (850 nanometers, short
wavelength, Gigabit Ethernet) connectivity. The 450-1SX provides one
1000BASE-SX port. The 450-1SR provides one 1000BASE-SX port and one
LinkSafe redundant port.
Operating Range
Table B-1 lists the operating range for the 1000BASE-SX models.
