Refurbished 15454-AR-MXP Cisco Muxponder Card
Refurbished 15454-AR-MXP Overview
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.
Refurbished 15454-40-SMR2-C Cisco Single Module ROADM multiplexer
Refurbished 15454-40-SMR2-C Overview
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.
Refurbished 15454-10G-XR Cisco Based Multiple-Reach Optics Cards
Refurbished 15454-10G-XR Overview
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.
Refurbished 15454-10G-S1 Cisco Based Optics Cards expansion module
Refurbished 15454-10G-S1 Overview
The Cisco ONS 15454 OC-192/STM-64 XFP-Based Optics Card provides a single XFP-based pluggable optics module.

Refurbished 15454-10EX-L1-C Overview
Cisco 4x 2.5-Gbps Muxponder Card EFEC Full C-Band Tunable expansion module
Refurbished 14X10GBE-WL-XFP Cisco CRS-3 14-Port 10GE module
Refurbished 14X10GBE-WL-XFP Overview
Cisco CRS-3 14-Port 10GE LAN/WAN-PHY Interface Module expansion module
Refurbished 15216-DCU-1350 Cisco Dispersion Compensation Unit
Refurbished 15216-DCU-1350 Overview
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.
