This SFPoperates at 1550 nm and has a reach of up to 120 km. The part number ofthis SFP is AA1419071-E6.CAUTIONTo prevent damage to the optical receiver, ensure that at least 14dB of attenuation is present between the transmit and receiveports.To attain the BER of 10 -12 , the minimum attenuation between thetransmit and receive ports is 15 dB.1000BASE-EX DDI SFP specificationsParameter SpecificationsMaximum electrical power consumption 1.2 WConnectors Duplex LCCabling SMF, 9 μmData rate 1.0 Gbit/sLine rate (8B/10B code) 1.25 Gbit/sLink optical power budget 30 dBMaximum dispersion power penalty 2.0 dB at 120 kmTransmitter characteristicsLaunch power 0 to 5.0 dBmReceiver characteristicsReceiver sensitivity -30 dBmMaximum receiver power -9.0 dBmNortel Metro Ethernet Routing Switch 8600Installation — SFP, XFP, and GBIC Hardware ComponentsNN46220-301 02.02 Standard4.2 13 November 2007Copyright © 2007, Nortel Networks.
