Vnet 2516J

VNET2516K is one RU height single-board Layer 2 Gigabit Ethernet switch which has been designed as ultra-compact customer premise equipment.

The VNET2516K provides 16-port interfaces which support super-fast mode simultaneously with the RJ45 connectors and 2 mounting slots for an optional uplink unit. It also has a non-blocking architecture and interfaces providing wire-speed and full-duplex packet traffic on all ports.

For the uplink interface unit, it supports 1000Base-X (SFP), 10GBase-R (SFP+), EPON module type to provide a wider bandwidth and a longer trans-mission distance.

N-iTUS’s works with ADSL and VDSL through vectoring which effectively removes all crosstalk through noise cancellation technology. This enables service providers leverage their existing DSL and make a smooth transition to ultra-broadband with solution ultimately lowers TCO by eliminating the need to invest for all fiber infrastructure, and extends ultra-broadband to old buildings that only have telephone lines or the legacy areas.

It is an effective product to network environment of entry-level enterprise, mid-market and branch office networks, a large scale place of business and ISP (Internet Service Provider) to support high-speed internet service than existing Ethernet products. It offers flexible in-terface to make up diversity network services and benefit of network extension.
