Tjo Dom jag har skicka mail med är, OpticalZonu.com Dom ska också ha en sfp med följande spec: AF6-D51G.1-LU or AF6-D61G.1-LU => iSFC FE/STM1 CWDM DFB Laser; 34 dB for data transport; 65 dB DR for Micro-OTDR; Duplex LC/UPC Receptacle. This 100 Km Class model is a good choice for retrofit of existing installations, as well as for new new installations, where two fibers must be monitored and there is only a single SFP slot devoted to the OSC. FE or STM1 data may be transported and 65 dB Dynamic Range for the Micro-OTDR is needed to support the spans required between the fiber amplifiers for the DWDM gear and the terminal equipment for the OSC gear. The Micro-OTDR exists on the Transmitter "path" and monitors that fiber from the single end. To monitor both fibers, this Micro-OTDR must be deployed on both sides of the Link. To avoid the DWDM "window", either 1511 nm or 1611 nm may be used. Men om man frågar snällt kan dom kanske göra en 1528nm också <<Magnus Torbjörn Rium wrote:
