Ethernet speeds: 1Gbps, 10Gbs, 100Gbps
Available speeds: STM-1, STM-4, STM-16, STM-64
SDH service allows you to have your own transmission channel with defined capacity.
SDH provides transmission pipes that run between the network nodes.
Ethernet-over-SDH provides the capacity to transport packet-based traffic over the SDH backbone with high reliability and low latencies.
Synchronous Digital Hierarchy is primarily used in the telecommunication industry to carry telephony traffic.
OTN – Optical Transport Network
Is a next-generation, industry-standard protocol that provides an efficient and globally accepted way to multiplex different services onto optical light paths.
OTU-2 – transports OC-192, STM- 64 or 10G Ethernet.
OTU-4 – transports a 100 Gigabit Ethernet signal.
