The Cisco 1GBASE DWDM SFP+ Modules are fiber line cards for a wide variety of Cisco switches, routers, and other equipment. They allow enterprises and service providers to provide scalable and easy-to-deploy 1-Gbps LAN, WAN, and optical transport network (OTN) services in their networks. The Cisco 1GBASE Dense Wavelength-Division Multiplexing SFP+ Module offer the following features and benefits: - Supports 1-Gigabit data rates from 9.9G to 11.1G (LAN, WAN, and OTU2/OTU2e) to accommodate different applications - Smallest SFP+ module footprint in the industry - Hot-swappable input/output device plugs into an Ethernet SFP+ port of a Cisco switch or router to link the port with the network - Support for a “pay-as-you-grow” model for investment protection - Digital optical monitoring capability for enhanced diagnostics and troubleshooting - DWDM fixed module supports 4 non-tunable ITU 1-GHz wavelengths - DWDM tunable module supports 96 tunable ITU 5-GHz wavelengths - Supports the Cisco quality identification (ID) feature, which enables a Cisco switch or router to identify whether or not the module is an SFP+ module certified and tested by Cisco https://elecena.pl/product/30648084/cisco-dwdm-sfp10g-42-14-dwdm-sfp-1542-14nm-network-transceiver-module-fiber 2026-09-01 https://elecena.pl/product/30648084/cisco-dwdm-sfp10g-42-14-dwdm-sfp-1542-14nm-network-transceiver-module-fiber 2026-09-25
