Product Description

The NL 3120 is a bonded A/VDSL Gigabit Wireless Router that can offer competitive Broadband speeds to FTTx deployments in last-mile copper deployments. Offer the latest in bonding (up to profile 17a) with up to twice the downstream/ upstream bandwidth over comparable single-line models Reduce or avoid customer WiFi complaints with the latest Quantenna 802.11ac Wave 2 technology Take advantage of the latest high-bandwidth applications and services, such as streaming HD and UHD IPTV, access to cloud-based resources, and demanding online gaming Reduce truck rolls with remote management to easily.


Maximizes Video Streaming
11ac 5GHz technology with 4×4 multi-user MIMO (MU-MIMO) and dynamic beamforming technology provide an enhanced video experience.

Allows for Deployment Versatility
Use a single unit for copper and fiber deployments. Equipped with a combo WAN/LAN port to be configured either as WAN for fiber deployments or an additional LAN port for copper deployments.

Provides Optimized Performance
Supports the latest G.vector & G.inp technologies to work together to mitigate crosstalk and impulse noise resulting in greater throughput.

Future-Proofs with A/VDSL
The NL 3120 offers VDSL2 with ADSL2+ fallback for flexible future transitional deployments. Use a single unit for both ADSL2+ and VDSL2 deployments.
