Selecting an SFP 21CWDM SFPs are designed to support high speed data communicationsfor Metropolitan Area Networks (MANs). The system uses a grid of eightCWDM optical wavelengths in both ring and point-to-point configurations.All components are color-coded by wavelength.ATTENTIONThe attainable cable length can vary depending on the quality of the fiber opticcable used.SFP models without DDI supportModel and connector Product number Description1000BASE-SX (LC) AA1419013-E5 850 (nm), up to 275 or 550 m1000BASE-SX (MT-RJ) AA1419014-E5 850 nm, up to 275 or 550 m1000BASE-LX (LC) AA1419015-E5 1310 nm, up to 10 km1000BASE-XD CWDM (LC) AA1419025-E5 toAA1419032-E51470 nm to 1610 nm, up to 40 km1000BASE-ZX CWDM (LC) AA1419033-E5 toAA1419040-E51470 nm to 1610 nm, up to 70 kmFor specifications for these SFPs, see "SFP specifications" (page 31).Procedure job aid: SFP models with DDI supportAny Digital Diagnostic Indicating (DDI) SFP can be used in any EthernetRouting Switch module that supports SFPs. The optical functions of theSFP are supported. Access to the DDI information will be provided ina future release.The SFPs described in this section are all RoHS -E6 compliant.The following table lists and describes the Nortel SFP models with DDIcapability. All these SFPs use LC connectors.SFP models with DDI capabilityModel Product number Description1000BASE-T (RJ-45) AA1419043-E6 CAT5 UTP, up to 100 m. Note thatbecause the 1000BASE-T device isall electrical, there is no need for DDIsupport.1000BASE-BX (LC type) AA1419069-E6,AA1419070-E6Bidirectional 1310 nm and 1490 nm, upto 10 kmFor specifications for these SFPs, see "SFP specifications" (page 31).Nortel Ethernet Routing Switch 8300Installation — SFPs and XFPsNN46200-307 01.02 Standard4.0 27 August 2007Copyright © 2007, Nortel Networks.
