Cisco ASR 900 series Ethernet interface modules are designed to give customers a high degree of flexibility and value. All Ethernet interface modules share a common core that supports time stamping on the module for Y.1731 operations, administration, and maintenance (OAM) delay measurement functions to achieve precise results for one-way and two-way delay measurement. The modules also provide time-stamping functions for the IEEE 1588-2008 protocol. These time stamps help ensure that the Cisco ASR 900 Series Aggregation Services Routers achieve outstanding results when deploying IEEE 1588-2008 protocols for frequency and phase synchronization. Not all customers will deploy IEEE 1588-2008 for synchronization; therefore, the Ethernet interface modules also support input and output frequency synchronization using synchronous Ethernet (SyncE).
Cisco CE Series Multirate Ethernet Card expansion module. Through its portfolio of Ethernet service cards, the Cisco ONS 15454 MSPP has enabled service providers and enterprises to effectively and efficiently expand their network capability from transporting only time-division multiplexing (TDM) services to delivering multiple services over a single, converged architecture and eliminating the need for multiple overlay infrastructures.

Cisco ASR 900 Series Interface Modules
Metro transport networks must support numerous service demands: transmission of low-rate 10/100BASE-T and OC-3/STM-1 signals; higher-rate OC-12/STM-4, Gigabit Ethernet, OC-48/STM-16 signals; video signals such as standard-definition Serial Data Input (SDI) and high-definition SDI (HD-SDI); optical-transport-unit-1 (OTU-1) services; and first-generation (1G), 2G, 4G, and 8G Fibre Channel services. The flexibility to support multiple rates and aggregate them over a dense wavelength-division multiplexing (DWDM) interface using OTN technology brings huge savings in operating and management costs.
Cisco NCS 2000 Flex Spectrum Single Module ROADM line cards create an agile DWDM layer forming the foundation for converged transport architectures, delivering features that allow programmability and agility in provisioning and recovery operations. Wavelength add/drop and routing are entirely software-driven, which eliminates manual operations, helps decrease operating expenses (OpEx), and reduces provisioning and recovery times.
The Cisco ONS 15454 OC-192/STM-64 XFP-based optics card provides a single XFP-based pluggable optics module. The multiple-rate optics card operates in either Cisco ONS 15454 SONET or SDH systems, providing multiple-reach capabilities including short-reach/inter-office (SR/IO), intermediate-reach/short-haul (IR/SH), and long-reach/long-haul (LR/LH). Additionally, the SR/IO-only card provides a cost-effective, fixed SR/IO configuration to support first cost-sensitive installations where flexibility is not paramount.

Cisco Dispersion Compensation Unit 1350 expansion module. As metropolitan (metro) transport networks grow from 2.5-generation (2.5G) services to 10G and eventually 40G, the underlying optical systems need to compensate for the lower chromatic dispersion tolerances on the 10G and 40G interfaces. In optical networks, the dispersion compensation unit (DCU) compensates for accumulated chromatic dispersion effect in fiber. It provides a flexible solution for accumulated chromatic dispersion without dropping and regenerating the wavelengths on the link, a process that would otherwise be necessary when accumulated chromatic dispersion exceeds the maximum allowed dispersion tolerance.
