54 SFP specificationsATTENTIONFor the 40 km CWDM SFPs, a minimum attenuation of 4 dB must be presentbetween the transmitter and receiver. To avoid receiver saturation, you must inserta minimum attenuation of 4 dB when you test the CWDM SFP in loopback mode,or use short runs of fiber with no intermediate CWDM OADM or CWDM OMUX.To determine the expected signal loss for an optical add drop multiplexer (OADM),an optical multiplexer (OMUX), or fiber length, see Nortel Ethernet Routing Switch8600 Planning and Engineering — Network Design (NN46205-200).1000BASE-ZX CWDM SFP specificationsATTENTIONFor the 70 km CWDM SFPs, a minimum attenuation of 10 dB must be presentbetween the transmitter and receiver.The part numbers of the 70 km models range from AA1419033-E5 toAA1419040-E5.1000BASE-ZX CWDM (70 km) SFP specificationsParameter SpecificationsConnectors Duplex LCCabling SMF, 9 μmData rate 1.0 Gbit/sLine rate (8B/10B code) 1.25 Gbit/sOperating temperature range 0 to 60CLink optical power budget 20 dBTransmitter characteristicsLaunch power -3.0 to 2.0 dBmReceiver characteristicsReceiver sensitivity -23 dBmMaximum input power -3.0 dBm1000BASE-SX DDI SFP specificationsThe following table describes the 1000BASE-SX DDI SFP, which has a reachof up to 550 m using 50 μm MMF, and of 275 m using 62.5 μm MMF.
