1000Base-SX MM/LC 550m Range SFP Fiber Transceiver, 850nm
1000Base-SX Small Form Pluggable SFP Fiber Optic Transceiver module, LC, MM 850nm
1000BASE-SX is a fiber optic gigabit Ethernet standard for operation over multi-mode fiber using a 770 to 860 nanometer, near infrared (NIR) light wavelength.
The standard specifies a distance capability between 220 metres (62.5/125 µm fiber with low modal bandwidth) and 550 metres (50/125 µm fiber with high modal bandwidth). In practice, with good quality fiber, optics, and terminations, 1000BASE-SX will usually work over significantly longer distances.
This standard is highly popular for intra-building links in large office buildings, co-location facilities and carrier neutral internet exchanges.
Optical power specifications of SX interface: Minimum output power = -9.5 dBm. Minimum receive sensitivity = -17 dBm.
