AddOn Networks CWDM SFP 1G 1610nm 120 km | Cisco Compatible LC — CWDM-SFP-1610-120-AO

Keep critical Ethernet links alive across distances that standard multimode optics cannot reach. The AddOn Networks CWDM SFP delivers 1 GbE connectivity at 1610 nm over single-mode fiber, with support for up to 120 km in the right optical budget and infrastructure design. Its LC duplex interface and SFP form factor make it straightforward to deploy in Cisco-compatible switches, routers, and media platforms that require long-reach optical transport. This module is a practical fit for metro aggregation, campus backbones, and inter-building runs where replacing copper with fiber reduces distance constraints and signal loss. CWDM wavelength planning also helps teams preserve fiber resources while extending service across existing plant. For infrastructure teams, that means fewer compromises when designing resilient links between network rooms, data centers, and remote facilities. Choose this class of optic when the cost of downtime, truck rolls, or bandwidth bottlenecks outweighs the price of a standard short-reach transceiver. It is built for environments where link stability, compatibility, and reach are more valuable than commodity pricing. Ideal For Metro aggregation links between network sites Campus backbone connections across separate buildings Long-reach switch-to-switch fiber runs Remote facility uplinks where copper is not viable Why This Product 1 Longer reach than standard short-range SFP optics 2 CWDM wavelength planning reduces fiber strain in dense networks 3 LC duplex interface fits common enterprise fiber plant 4 Cisco-compatible SFP design simplifies replacement planning
