OMCI (Optical Network Unit Management Control Interface, ONU Management and Control Interface) is a protocol for information exchange between the OLT and ONT defined in the GPON standard. It is used for the management of ONTs by the OLT in the GPON network:
- Configuration management,
- Fault management,
- Performance management,
- Security management.
OMCI is mainly a master-slave stop management protocol, where the OLT is the master device and the ONT is the slave device. The basic process is that the OLT sends a management message and waits for an ONT response. After receiving the response or timeout, it continues to issue the next message.OMCI allows service providers to create a variety of applications and services utilizing the PON (Passive Optical Network), including voice, video and data, and features inherent flexibility.
The OMCI protocol is at the high-level control level of the GPON system, and refers to the high-level service configuration and performance management. ITU-TG.984.4 protocol defines the application scope and application mode of OMCI protocol in GPON system. In the GEM mode, each OMCI message is encapsulated in a GEM frame. The OMC1 message consists of 53 bytes. The message content is: GEM lock, transaction-related identifier, message type, device identifier, message identifier, Message content and CRC trailer field.
BAUDCOM GPON ONU all can support OMCI protocol.
