Brand:

Cisco

Cisco 1000BASE-CWDM GBIC transceiver for 1570nm single-mode fiber connectivity in compatible Cisco Gigabit Ethernet and CWDM optical networks.

OVERVIEW

Cisco CWDM-GBIC-1570= is a 1000BASE-CWDM optical transceiver designed for 1570nm transmission over single-mode fiber in compatible Cisco networking environments. Its dedicated 1570nm wavelength gives it a defined position within Cisco's eight-channel CWDM family, while the GBIC form factor and SC connector distinguish it from the corresponding CWDM SFP implementation. It is intended for established optical architectures such as enterprise campus backbones, inter-building links, service-provider networks and CWDM systems using compatible Cisco equipment. For procurement teams, its greatest value is wavelength-specific replacement or expansion where the existing optical design already calls for 1570nm. Cisco identifies the 1570nm model as single-mode only and assigns Orange as its wavelength color code, making identification within a multi-channel CWDM deployment straightforward.

USE CASES

Enterprise campus backbone connectivity over compatible single-mode fiber
Inter-building Gigabit Ethernet links using an established CWDM architecture
Replacement of an existing Cisco 1570nm CWDM GBIC in compatible equipment
CWDM wavelength-channel deployment where 1570nm is assigned to a specific optical link
Network maintenance programs supporting legacy Cisco GBIC-based infrastructure
Optical aggregation environments using compatible Cisco CWDM components
CWDM OADM deployments requiring the 1570nm channel
CWDM mux/demux systems carrying multiple Gigabit Ethernet wavelengths
Infrastructure continuity projects designed to preserve installed single-mode fiber assets
Targeted optical replacement where the host platform and wavelength plan must remain unchanged
