Cisco CWDM-GBIC-1530 1000BASE-CWDM 1530nm Module for Optical Links

Brand:
Cisco

Cisco 1000BASE-CWDM GBIC transceiver using the 1530nm wavelength for single-mode fiber connectivity in compatible Cisco Gigabit Ethernet and CWDM environments.

OVERVIEW

  • Cisco CWDM-GBIC-1530= is a 1000BASE-CWDM optical transceiver designed for Gigabit Ethernet connectivity over single-mode fiber at the 1530nm wavelength. Its primary distinction within the Cisco CWDM family is the dedicated 1530nm channel, identified by a green color code, while the GBIC form factor and SC interface differentiate it from Cisco CWDM SFP implementations. It is suited to compatible Cisco networking platforms, CWDM mux/demux or OADM architectures, enterprise campus backbones and service-provider optical infrastructure where existing fiber assets need to be retained. For procurement teams, the exact wavelength and legacy GBIC interface make this model valuable for targeted replacement or expansion rather than broad platform refreshes. Cisco documentation lists CWDM-GBIC-1530= as a single-mode 1000BASE-CWDM model and places it within an eight-wavelength CWDM family.

USE CASES

  • Enterprise campus backbone connectivity over installed single-mode fiber
  • Replacement of a failed or aging 1530nm CWDM GBIC in compatible Cisco equipment
  • CWDM wavelength-channel deployment where 1530nm is part of the optical plan
  • Inter-building Gigabit Ethernet links using single-mode fiber infrastructure
  • Network modernization projects that retain compatible Cisco GBIC-based platforms
  • Service-provider optical access or aggregation environments using compatible CWDM equipment
  • CWDM mux/demux architectures carrying multiple Gigabit Ethernet wavelength channels
  • Cisco network lifecycle projects requiring wavelength-matched optical replacement
  • Optical infrastructure expansion without changing an established 1530nm CWDM channel
  • Fiber-network consolidation where multiple CWDM wavelengths share the same fiber infrastructure

KEY FEATURES

  • 1000BASE-CWDM Gigabit Ethernet optical interface
  • Dedicated 1530nm CWDM wavelength
  • Single-mode fiber operation
  • Cisco CWDM GBIC family architecture
  • GBIC form factor for compatible Cisco equipment
  • SC optical connector interface
  • Green wavelength identification for the 1530nm channel
  • Designed for wavelength-based CWDM network architectures
  • Works as part of Cisco CWDM OADM and mux/demux deployments where supported
  • Suitable for targeted optical-module replacement projects
  • Supports continued use of compatible single-mode fiber infrastructure
  • Provides a wavelength-specific option within the Cisco eight-channel CWDM family
  • Useful for enterprise and service-provider optical networking environments
  • Supports infrastructure expansion based on an existing CWDM wavelength plan
  • Procurement-focused replacement option where exact host and optical compatibility are confirmed
