PDH Fiber Multiplexer

Kakaretso

Letoto lena la lisebelisoa ke k'hamphani e ntlafalitseng PDH fiber transmission e inehetseng ea VLSI e ntlafalitsoeng motheong oa lisebelisoa tsa optical transmission. Fana ka li-interface tsa 1-4 E1, sehokelo sa mantlha le se bolokang fiber optical interface, 1-4 ea ho itšehla thajana ea 10/100M Fast Ethernet interface (e ikemetseng ea terata e mene lebelo 100M, kakaretso ea bandwidth ke 4 * 100M), hammoho le sehokelo sa katoloso ea khoebo tse peli. 2 Sesebelisoa se atolositsoeng sa lits'ebeletso se ka sebelisoa joalo ka data ea RS232 / RS485 / RS422 asynchronous, ts'ebeliso e bonolo haholo. Ho khetha mohala o le mong oa tšebeletso ea dijithale, ts'ebeliso e bonolo haholo. Ka ts'ebetso ea alamo ea molumo, ts'ebeliso eohle e tsitsitseng, e ka tšeptjoang, e tlaase ea matla, ho kopanya ho phahameng, boholo bo nyane.
