What is meant by OTN?

Also commonly called ‘digital wrapper,’ OTN—or Optical Transport Networking—is a next-generation, industry-standard protocol that provides an efficient and globally accepted way to multiplex different services onto optical light paths.

What is OTN card?

OTN comes with a rich set of interface cards which allow users to connect any kind of traditional, peripheral equipment easily. An OTN network consist of nodes interconnected by fibre. The nodes, housing the interface cards, are connected in a physical ring topology.

What is OTU1?

OTU1 has a line rate of approximately 2.66 Gbit/s and was designed to transport a SONET OC-48 or synchronous digital hierarchy (SDH) STM-16 signal. • OTU2 has a line rate of approximately 10.70 Gbit/s and was designed to transport an OC- 192, STM-64 or WAN PHY (10GBASE-W).

What is ODU optical?

What is the ODU/ODUk (Optical Data Unit)? An ODU (Optical Data Unit) is a data structure that Path Terminating Equipment (PTE) within an Optical Transport Network (OTN) will generate and monitor as it transmits and receives data.

What is OTU2e?

OTU2e has a line rate of approximately 11.09 Gbit/s and was designed to transport an 10 gigabit Ethernet LAN PHY coming from IP/Ethernet switches and routers at full line rate (10.3 Gbit/s). OTU4 has a line rate of approximately 112 Gbit/s and was designed to transport a 100 Gigabit Ethernet signal.

What is Roadm in telecom?

A reconfigurable optical add-drop multiplexer (ROADM) is a device that can add, block, pass or redirect modulated infrared (IR) and visible light beams of various wavelengths in a fiber optic network. ROADMs are used in systems that employ wavelength division multiplexing.

What is 10G WAN PHY?

The 10G-Ethernet standard specifies two types of PHY: LAN PHY and WAN PHY. 10G WAN PHY operates at a data rate compatible with SONET OC-192c and SDH STM-64, but 10G LAN PHY does not. “Today 10 Gigabit Ethernet is being widely deployed in education and enterprise networks.

What is OTN Node?

Concept. The basic building block of OTN is called a node. It is a 19″ frame that houses and interconnects the building blocks that produce the OTN functionality. Core building blocks are the power supply and the optical ring adapter (called BORA : Broadband Optical Ring Adapter) (ref).
