What is OTU3?
What is OTU3?
OTU3 has a line rate of approximately 43.01 Gbit/s and was designed to transport an OC- 768 or STM-256 signal or a 40 Gigabit Ethernet signal.[2] • OTU3e2 has a line rate of approximately 44.58 Gbit/s and was designed to transport up to four OTU2e signals.
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 ODU in networking?
Optical channel data unit (ODU)
What is ODU in DWDM?
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.
Is OTN a Layer 2?
The optical transport network (OTN) and WDM layers make up a generic Layer-1 transport network, enabling different service types to coexist and share the same infrastructure transparently, without affecting each other’s performance.
What is the difference between OTU and OTN?
Here OTU stands for Optical Channel Transport Unit and OTN stands for Optical Transport Network. • OTN (Optical Transport Network) consists of various optical network elements connected by optical fiber lines.
What is the OTU (optical transport unit) frame?
This post defines and describes the OTU (Optical Transport Unit) Frame that is used in OTN (Optical Transport Networks). Sharing is caring! What is the OTU Frame/OTUk Frame? An OTU (Optical Transport Unit) frame is a data structure that an OTN Terminal (or Source STE) will use to transport its data to the outside world.
What type of signal does the OTU client transport?
• It uses WDM (Wavelength Division Multiplexing) unlike SDH/SONET. The figure-1 depicts OTU client signal mapping. It transports SONET OC-48 or SDH STM 16. It transports OC-192, STM-64 or WAN PHY for 10GBase-W . It transports OC-768, STM-256 ot 40 GB ETHERNET. It transports 100 GB ETHERNET Signal.
What are the standard line rates used by OTN?
As of December 2009, OTN has standardized the following line rates. Transports a 10 Gigabit Ethernet local area network (LAN) PHY coming from IP/Ethernet switches and routers at full line rate (10.3 Gbit/s). This is specified in G.Sup43. Transports a 10 Fibre Channel.
