3.9 MoCA interface specifications
The following technical specifications apply to MoCA ONTs:
RF interface connector: F-type with 75 Ω impedance
•
•
MoCA 1.0 and 1.1 compliant
•
Network center frequency: 1 000 MHz
MAC throughput (MAC rate) is the maximum rate at which Ethernet packets can be
forwarded across the MoCA network while maintaining a PER of 10
lists minimum MAC rates for the specified maximum PHY rates, for MoCA v1.0 and
v1.1. This applies for flat channels between two intermediate devices with 100 Mb/s
or 1 Gb/s Ethernet PHY interface in a two-node MoCA network, with 1518-byte
packets.
PHY rate (Mb/s)
275 (4)
250 (4)
Notes
(1) MAC rates are aggregate (half traffic in one direction, and half in the opposite direction) and assume a 1518-byte
maximum frame size.
(2) For MoCA v1.0 with less than 1518-byte frame size, the minimum aggregate MAC rate is 9500 packets/s.
(3)
For MoCA v1.1, packet aggregation allows a minimum MAC rate of 20 000 packets/s for 800-byte frames.
(4) Maximum PHY rate is approximately 275 Mb/s when connected devices support optional QAM-256; otherwise the
maximum PHY rate is approximately 250 Mb/s when using QAM-128.
The nominal transmit output power for MoCA ONTs is as follows:
•
For Package B MoCA ONTs, the nominal transmit output power will be the
values programmed via TL1 (range 0 to -30 dBm).
•
For Package A MoCA ONTs, Table
variance for the values programmed via TL1.

Note —
MoCA ONTs only support MoCA v1.1 when connected to
nodes that support MoCA v1.1. They revert to MoCA v1.0 if
connected to nodes that only support MoCA v1.0.
