What is SDH?
Synchronous Digital Hierarchy (SDH) is a standardized digital communication protocol that transmits data over fiber optic cable. It's used primarily to transport large quantities of data, voice, and video traffic in telecommunications networks. SDH defines a hierarchical set of transmission rates, enabling efficient multiplexing and demultiplexing of lower-rate signals. It is the international equivalent of SONET.
What other technologies are related to SDH?
SDH Competitor Technologies
PDH
PDH is a lower-speed, older technology for digital transmission that SDH replaced.
OTN
OTN is a more modern technology that can perform similar functions to SDH, and provides improvements in terms of framing, multiplexing, and management capabilities.
MPLS-TP
MPLS-TP provides connection-oriented transport and can be used as an alternative to SDH in some scenarios.
PTN
Packet Transport Network. Can be an alternative transport technology to SDH
SONET
SONET is the North American equivalent of SDH. Both are closely related and provide similar functionality, which means they are competitors in different regions.
IP/MPLS
IP/MPLS is a packet-based technology that can be used as an alternative to SDH for data transport.

SDH Complementary Technologies
DWDM
DWDM increases the capacity of optical fiber, and SDH signals can be transported over DWDM systems. It's complementary because DWDM provides the physical layer transport, and SDH provides the framing and management.
EoSDH
No summary available
Ethernet over SDH encapsulates Ethernet frames within SDH for transport, therefore they are complementary.
SNCP
No summary available
SNCP (Subnetwork Connection Protection) is a protection mechanism used within SDH networks.
