The Cisco® Dense Wavelength-Division Multiplexing (DWDM) Small Form Factor Pluggable (SFP) module (Figure 1) allow enterprise companies and service providers to provide scalable and easy-to-deploy Gigabit Ethernet or Fibre Channel services in their networks.
Figure 1. Cisco DWDM SFP Module
Main features of the Cisco DWDM SFP include:
• Support for International Telecommunication Union (ITU) 100-GHz wavelength grid
• Match for wavelength plan of Cisco 100-GHz ONS product family
• Fixed-wavelength SFP, with 40 different SFP models
• Hot-swappable input/output device that plugs into Gigabit Ethernet SFP ports or slots of a Cisco switch or router, linking the port with the network
• Equipment: standard SFP interface network: dual LC/PC connector
Note: Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported.
All cables and cable assemblies used must be compliant with the standards specified in the standards section.
Environmental Conditions and Power Requirements
• Operating temperature range: 32 to 158°F (0 to 70°C)
• Storage temperature range: -40 to 185°F (-40 to 85°C)
Dimensions
• Dimensions (H x W x D): 8.5 x 13.4 x 56.5 mm
• Cisco SFPs typically weigh less than 75 grams.

Note:
a) Parameters are specified over temperature and at end of life unless otherwise noted.
b) OSNR is measured at 0.1nm resolution bandwidth.
c) Receiver performance is always specified for a BER < 10e-12.
Note: When shorter distances of single-mode fiber are used, it might be necessary to insert an optical attenuator in the link. At least 1 dB of attenuation is required to prevent damaging the optical receiver, and at least 9 dB of attenuation are required to avoid receiver overloading conditions.
Warranty
• Standard warranty: 90 days
• Extended warranty (option): available under a Cisco SMARTnet® support contract for the Cisco switch or router chassis or available under separate SMARTnet Product IDs specific for DWDM SFPs.
