What is 1000Base-SX?

1000BASE-SX is a fiber optic gigabit Ethernet standard. It operates over multi-mode fiber using a 850 nanometer, near infrared (NIR) light wavelength. The standard specifies a distance capability between endpoints of 220 m over 62.5/125 µm fibre although in practice, with good quality fibre and terminations, 1000BASE-SX will usually work over significantly longer distances. Modern 50/125 µm fibres can reliably extend the signal to 500 m or more. This standard is highly popular for intra-building links in large office buildings, colocation facilities and carrier neutral internet exchanges. Typical optical power parameters of SX interface: maximum mean output power = -5 dBm; stressed receiver sensitivity = -14 dBm.

What is MT-RJ?

The MT-RJ (Mechanical Transfer Registered Jack) uses a form factor and latch like the RJ-45 connectors, supports full duplex, has lower cost than ST or SC connectors, and is easier to terminate and install than ST or SC. Further, its smaller size allows twice the port density on a face plate than ST or SC connectors do. The MT-RJ connector was designed by AMP, but was later standardized as FOCIS 12 (Fiber Optic Connector Intermateability Standards) in EIA/TIA-604-12.
