FAQ：
Q:Is it necessary to clean a transceiver's optical connector?
A:Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, HTF strongly recommends cleaning both connectors each time you disconnect and reconnect them.
Q:What's the operating temperature of the 1000BASE SX transceivers?
A:The 1000BASE-SX SFP transceivers operate at a commercial temperature range (0 to 70°C). Also, industrial temperature range are available for custom.
Q:What cable type is needed for 1000BASE SX transceivers?
A:The 1000BASE-SX SFP transceivers use duplex multimode fiber patch cables with LC/UPC connectors, both OM1 and OM2 are feasible.
Q:What's the 1000BASE SX transceivers max supported distances?
A:The 1000BASE-SX SFP transceivers support up to 550m on OM2 multimode fibers.
