Do You Know the Distinctions of Huawei GPHF GPUF GPSF and GPLF?

GPHF GPUF Difference

GPHF GPUF GPSF and GPLF, 16-port GPON interface board, applied to Huawei MA5800 OLT. All of these boards are almost same appearance, but they are in some different features and functions.

GPHF

The following table lists all the parameters, “Yes” stands for support,  “No stand for “not support”.

Power budget supported by a GPON port Class B+ (28.5 dB, mostly used),
Class C+ (32 dB, longreach transmission)
Class C++: 35 dB
Minimum bandwidth supported by a T-CONT 1 Mbit/s (in the minimum delay mode)
128 kbit/s (in the maNoimum bandwidth usage mode)

In summary:

1, GPHF is better performance than the other 3 boards, and have more functions and application scenario supported;

2, Only GPFD supports HQoS, PON ISSU and D-CCAP;

3, GPUF and GPSF do not support 9K Jumbo frames.
