2 Product Introduction
Item
Description
The GPON system adopts the single-fiber bidirectional
transmission mechanism, using the TDMA mode with the
wavelength 1310 nm in the uplink direction, and the broadcast
mode with the wavelength 1490 nm in the downlink direction.
Supports embedded OAM messages, PLOAM messages and
OMCI messages.
Supports slicing of data messages and OMCI protocol
messages in the uplink direction. Message slices with both
adaptive length and fixed length are supported.
GEM port
Supports bearing the downlink broadcast messages and
unknown multicast messages via the broadcast GEM ports.
Supports mapping from GEM ports to T-CONTs.
Supports multiple flow mapping modes:
Supports the GEM port loopback.
T-CONT
Supports the T-CONTs of Type1 to Type 5.
A T-CONT supports no less than 64 GEM ports.
Supports eight T-CONTs.
DBA
Supports DBA in the SR and NSR modes.
Supports DBA Piggy-back DBRu Mode 0.
FEC
Supports bi-directional FEC: downlink FEC decoding and
uplink FEC encoding.
Supports downlink FEC performance statistics.
Encryption
Supports encryption for the downlink unicast data channel.
Supports the AES-128 encryption algorithm.
Supports generation of the key and response to the OLT's
request for key.
Supports OMCI channel encryption.
Registration
authentication
Supports the ONT registration process as specified in ITU-T.
G.984.3.
Supports four authentication modes: SN, Password, SN
＋
Password and LOID.
Supports performance statistics for the Ethernet interface.
Supports performance statistics for the GEM ports.
Ethernet
Complies with the IEEE 802.3 standard.
Supports configuring the Ethernet interface rate, working
mode, and MDI/MDIX auto-negotiation mode.
Supports manual configuration of the rate 10/100/1000 Mbit/s.
