CISCO CWDM-SFP-1590 Compatible CWDM SFP | 1,590 nm, 1 Gbps, SFP — CWDM-SFP-1590-ENC

Keep single-fiber transport efficient with a Cisco-compatible CWDM SFP tuned to 1,590 nm. This module is designed for 1 Gbps optical links in environments where wavelength planning, port density, and predictable interoperability matter more than commodity optics. For campus backbones, metro aggregation, and point-to-point extensions, CWDM optics help preserve fiber capacity by carrying multiple services across distinct wavelengths. That makes this module a practical choice when you need to add capacity without pulling new fiber or redesigning the transport layer. The standard SFP form factor simplifies deployment in supported switches and routers, while the CWDM design supports disciplined optical architectures that scale better than generic short-reach transceivers. For teams comparing price points, the value here is not just compatibility — it is the ability to keep a production link aligned to a specific wavelength plan with the right optical profile for the job. Ideal For Metro aggregation links where fiber is limited Campus backbone extensions requiring wavelength-specific optics Single-fiber transport deployments in managed switch environments Replacement optics for Cisco-compatible CWDM ports Why This Product 1 Wavelength-specific CWDM optics for planned fiber architectures 2 1,590 nm tuning for dense multi-channel transport 3 Standard SFP fit for broad switch and router compatibility 4 Better suited to managed optical networks than generic short-reach modules
