A GEM Port ID is unique per GPON interface and represents a specific traffic or group of flows between the OLT and the ONT There are 2 types of GEM Channels: Downstream-only GEM Channels -
- Whats GEM Frame and T-CONT of GPON? - Blogger
All service streams are encapsulated into the GEM frame and transmitted over GPON lines The service streams are identified by GEM ports and each GEM port is identified by a unique port ID The port ID is globally allocated by the OLT
- GEM ports description and usage in the GPON technology - Technopediasite
The GPON technology has introduced the GEM channel as part of its GPON Transmission Convergence (GTC) layer In fact the GEM channels carry variable-length frames and also including Ethernet frames GEM channels are identified by a uniquely assigned identifier, the GEM Port ID
- Understand GPON Technology - Cisco
GPON transmission convergence (GTC) frames that contain GEM PDUs are broadcast to all ONT ONUs connected to the GPON port ONT ONU filters the received data based on the GEM port ID contained in the GEM PDU header and retains the data only significant to the GEM ports on this ONT ONU

Within each bandwidth allocation, the ONU uses the GEM Port-ID as a multiplexing key to identify the GEM frames that belong to different upstream logical connections A Transmission container (T-CONT) is an ONU object representing a group of logical connections
- Definition and Function of Traffic-Table, DBA-profile, TCONT, GEM, GEM . . .
ont-lineprofile is a profile template used to contain TCONT, GEM GEM mappin A line profile describes the binding between the T-CONT and the DBA profile, the QoS mode of the traffic stream, and the mapping between the GEM port and the ONT-side service
- GPON Technology: How Does the Fiber Optic FTTH Network Work?
GPON Transmission Convergence (GTC) frames containing GEM PDUs are transmitted to all ONT ONUs connected to the GPON port The ONT ONU filters the received data based on the GEM port ID contained in the header of the GEM PDU and retains the data only significant for the GEM ports in this ONT ONU
