26 Small form factor pluggable transceivers
and alarm messages are mapped into WARNING and FATAL message
categories for system logging purposes. If an alarm or warning is generated,
the software does not automatically shut down the port.
CWDM SFPs are also supported. CWDM SFPs are designed to support
high-speed data communications. A CWDM system uses a grid of
wavelengths to provide multiple channels for both ring and point-to-point
configurations. All components are color-coded by wavelength.
Any DDM SFP can be used in any Metro Ethernet Services Unit 1800 or
1850 device or Metro Ethernet Routing Switch 8600 module that supports
SFPs. The optical functions of the SFP are supported. Access to the DDI
information is only provided for:
•
Metro ESU 1850
•
Metro Ethernet Routing Switch 8600 modules 8630 and 8683
Access to DDI information is not supported for:
•
Metro ESU 1800
•
Metro Ethernet Routing Switch 8600 module 8668
The SFPs described in this section are all RoHS -E6 compliant.
For information about DDM, see Nortel Metro Ether net Routing Switch 8600
Troubleshooting (NN46220-701).
The following table lists and describes the Nortel SFP models with DDI
capability. All the optical SFPs use LC connectors.
