1, standard rs***2, rs***5, rs***2 interfaces, *5kv esd protection; 2, the transfer retes of rs***2 interface can be up to *****0 bps; 3, because the port adaptice technology has been adoptded, from the rs***5 to rs***2 port can be adaptive without switch, so does the rate adjustment; 4, rs***5, rs***2 support upt to *2 poll environment 5, led indicator to show the device’s work state 6, meets with fcc, *5 class a, and ce standard. Technical parameters 1, standard: eia****-e, tia/eia****-a, tia/eia***2 2, interface: 1)an rs***2, rs**5, rs***2 interface, point to point application 2)an sc or st or fc optiocal interface 3, work mode: supports *-wire (half duplex) rs***5 and *-wire (full duplex) rs***2 mode 4, max transfer rate: rs***2 *****0 bps, rs***4, rs***2 *****0 bps; 5, transmission distance: multi-mode: 2 km, single mode *0 km; 6, working wavelength : multi-mode : **0nm, single mode ***0nm 7, power : 9~*6v dc, **0ma 8, relative temperature: **0~*5 9, relative humidity:5%~*5%; *0, fiber: 1)multi mode *0/**5, **0/**0, **0 2)single mode 8.3/**5, 8.7/**5 or *0/**5 Dimension: **2**8**5
