Get Data Sheet

Valiant Communications offers VCL-Gigabit Optical Add-Drop Multiplexer is a unique Gigabit multi-service optical fiber transport solution which transmits both Gigabit Ethernet (Gigabit Wire-Speed) data along with upto 16 E1 (TDM) channels over an optical fiber link. This product provides up to 4 x Gigabit interfaces with rate-limiting option on each port (with user selectable bandwidth allocation on each Gigabit port). 1+1 optical fiber redundancy is also available for minimizing the possibility of transmission loss due to an optical link failure.

The Gigabit (Wire-Speed) Ethernet traffic along with 16 E1's are multiplexed into 1.25Gbps optical link to provide a compact, high performance, high throughput and cost effective broadband network access solution.
