Selecting an SFP 21The SFPs described in this section do not have Digital Diagnostic Interfacecapability, and are RoHS -E5 compliant.CWDM SFPS are also supported. CWDM technology consolidatesmultiple optical channels on a common optical fiber. CWDM uses multiplewavelengths to expand available bandwidth.CWDM 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 km100BASE-FX (LC) AA1419074-E61310 nanometers (nm), up to 2 kmSupported by the 4526FX, 4526T,4526T-PWR, 4550T, 4550T-PWRand 4524GTT1 (RJ-48C) AA1419075-E61.544 Mbit/s Fast Ethernet to T1remote bridge.

The opticalfunctions of the SFP are supported. Access to the DDI information will beprovided in a future release.Ethernet Routing Switch 4500 SeriesInstallation — SFPs and XFPsNN47205-301 (324186-A) 01.04 Standard5.1 6 December 2007Copyright © 2007, Nortel Networks.
