Cisco Tri-Rate Multiprotocol SFPs
To ease management and sparing concerns, Cisco offers SFPs that can be used in both Fibre Channel (FC) and Gigabit Ethernet (GE) ports. The Cisco Tri-Rate Multiprotocol SFPs can run at 1- and 2-Gbps Fibre Channel and 1-Gbps Ethernet, thus enabling the user to use one type of SFP for all ports on the Cisco MDS 9000 family platform.
There are two types of Cisco Tri-Rate Multiprotocol SFP (Figure 6): the Cisco Tri-Rate Multiprotocol Shortwave SFP (part number DS-SFP-FCGE-SW) and the Cisco Tri-Rate Multiprotocol Longwave SFP (part number DS-SFP-FCGE-LW). Each product offers autosensing 1/2-Gbps Fibre Channel connectivity and 1-Gbps Ethernet connectivity.
Note: The fiber loss budget is derived from taking the difference between the minimum average transmit power and the minimum average receive power and subtracting the link penalties. The specified fiber loss budget should be used in calculating the maximum link distance.

Cisco 10-Gbps Ethernet X2 Transceivers
The Cisco Ethernet X2 Transceiver Short Reach (up to 300m; part number DS-X2-E10G-SR) enables high-performance Fibre Channel connectivity for the Cisco MDS 9000 family 10-Gbps Fibre Channel switching module to an existing Ethernet Dense Wavelength-Division Multiplexing (DWDM) transponder (Figure 11). The data format transmitted by the Ethernet X2 transceiver (DS-X2-E10G-SR) onto the fiber is identical to that transmitted by the Fibre Channel transceiver (DS-X2-FC10G-SR), except that the Fibre Channel packets are clocked at the 10 gigabit Ethernet rate, which allows Fibre Channel packets to be carried over an existing 10-Gbps Ethernet DWDM infrastructure. The Cisco MDS 9000 family 10-Gbps Fibre Channel switching module will automatically detect DS-X2-E10G-SR; no software configuration is required.
The Cisco MDS 9000 family offers cost-effective multiprotocol extended distance connectivity that optimizes the use of a customer's existing optical infrastructure through the Cisco Coarse Wavelength-Division Multiplexing (CWDM) SFP solution (Figure 12). The Cisco CWDM SFP solution has two main components: a set of eight wavelength-specific SFPs and a set of CWDM optical add-drop modules (OADMs). A Cisco CWDM chassis enables rack-mounting of up to two Cisco CWDM OADMs. The Cisco CWDM OADMs are passive and require no power or configuration.
The Cisco CWDM SFP solution enables the transport of up to eight channels over one pair of single-mode fiber strands, enabling enterprises to increase the bandwidth of an existing optical infrastructure without adding new fiber strands. The solution can be used in parallel with other Cisco SFP devices on the same platform.
Figure 13 shows a common point-to-point deployment scenario for the Cisco MDS 9000 family using the Cisco CWDM SFP solution. Two endpoints are directly connected through a fiber link. The Cisco CWDM SFP solution enables customers to add or drop up to eight channels onto a pair of single-mode fiber strands. As a result, the need for additional fiber is reduced. Redundant point-to-point links can be implemented by adding or dropping redundant channels onto a second pair of single-mode fiber strands.

Note:
• In typical point-to-point deployments, all wavelengths have a minimum reach of 40 km (24.8 mi).
• Parameters are specified over temperature and at end of life unless otherwise noted.
• When shorter distances of single-mode fiber are used, you may need to insert an inline optical attenuator in the link to avoid overloading the receiver.
• Up to 24 Cisco 4-Gbps CWDM SFP Transceivers are supported in a single Cisco MDS 9000 family switching module.
• When interoperating a Cisco 4-Gbps CWDM SFP Transceiver with a Cisco 1/2-Gbps CWDM SFP Transceiver, you must manually configure the port speeds on the Cisco 4-Gbps CWDM SFP Transceiver to 1 or 2 Gbps.

Cisco CWDM OADMs
Technical Specifications for Cisco CWDM OADMs
The Cisco CWDM OADMs are passive devices that provide the capability to multiplex and demultiplex, or add and drop wavelengths from multiple fibers onto one fiber. The OADM connectors are interfaced with color-matching Cisco CWDM SFPs on the equipment side. All modules are the same size. The Cisco CWDM chassis enables rack mounting for up to two Cisco CWDM OADMs in a single rack unit.
The Cisco MDS 9000 family offers two CWDM OADMs and a multiplexer and demultiplexer:
• Cisco Dual Fiber 4-Channel OADMs (part numbers DS-CWDMOADM4A= and DS-CWDMOADM4B=): This device allows you to add and drop four channels (with different wavelengths) onto one direction of an optical ring. The other wavelengths are passed through the OADM. Dual fiber is used for both network and SFP connections. The four wavelengths are set to 1470, 1490, 1510, and 1530 nm for DS-CWDMOADM4A=, and 1550, 1570, 1590, and 1610 nm for DS-CWDMOADM4B=.
• Cisco Dual Fiber 8-Channel Multiplexer/Demultiplexer (DS-CWDM-MUX8A=): This device allows you to multiplex and demultiplex eight separate channels onto one pair of fiber. Dual fiber is used for both network and SFP connections. The eight wavelengths are set to 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm.
Tables 47 and 48 provide comparisons of the OADM types.

Environmental Conditions and Power Requirements
The operating temperature range is 23 to 131°F (-5 and 55°C), and the storage temperature range is -40 to 185°F (-40 to 85°C).
The Cisco CWDM OADMs and the Cisco CWDM chassis are passive components that do not require power.
Dimensions and Weight
All the Cisco CWDM OADMs have the same dimensions: W x D x H: 21.2 x 3.0 x 26.5 cm. Two of these modules fit into one Cisco CWDM chassis. The Cisco CWDM chassis is one-rack-unit (1RU) in height and fits in a standard 19-inch rack.

The Cisco 4-Gbps DWDM SFP modules enable enterprises and service providers to provide scalable, easy-to-deploy DWDM Fibre Channel services in their networks. Direct integration of 4G DWDM optics in the Cisco MDS 9000 platform dramatically reduces capital and operational expenses for an FC over DWDM network, avoiding the need of DWDM Transponders and Muxponders.
The main features of the Cisco 4-Gbps DWDM SFP include:
• Support for International Telecommunication Union (ITU) 100-GHz wavelength grid
• Match for wavelength plan of Cisco ONS 100-GHz product family
• Fixed-wavelength SFP, with 40 SFP models
Ordering Information
Based upon customer usage, Cisco has identified and selected particular high-usage wavelengths, and will maintain shorter lead-times on these items. The short lead-time 4-Gbps DWDM SFP modules are from 1546.1 to 1560.6 with a 4 skip 1 approach. These part numbers are identified in Table 51. Table 52 identifies the rest of the 4-Gbps DWDM SFP modules.
The Cisco 10-Gbps Ethernet DWDM X2 Transceiver pluggable module (part number DWDM-X2-xx.xx=) enables high-performance Fibre Channel connectivity for the Cisco MDS 9000 family 10-Gbps Fibre Channel switching module to an existing Ethernet DWDM infrastructure. The data format transmitted by the Ethernet DWDM X2 transceiver (DWDM-X2-xx.xx=) onto the fiber is identical to that transmitted by the Fibre Channel X2 transceiver (DS-X2-FC10G-SR), except that the Fibre Channel packets are clocked at the 10 Gigabit Ethernet rate, which allows Fibre Channel packets to be carried over an existing 10-Gbps Ethernet DWDM infrastructure. The Cisco MDS 9000 10-Gbps Fibre Channel switching module will automatically detect DWDM-X2-xx.xx=; no software configuration is required.
The main features of the Cisco 10-Gbps Ethernet DWDM X2 Transceiver include:
• Support for 32 nontunable ITU 100-GHz wavelengths compatible with the Cisco ONS DWDM channel plan
• Support for digital optical monitoring capability
