Basic Layout of Huawei OLT

Today i will discuss about Basic Layout of Huawei OLT. Bellow are the details….

Basic Layout:

Chassis: bundled sales, not sold separately.

MPU: generally double master, one for main and one for standby, SCUN, MCUD (MA5608T) are common used.

Power Plate: generally dual power, one for main and one for standby, PRTE (DC), MPWC (DC), MPWD (AC) are common used.

Upstream board: GICF, GICG, X2CS etc.

GPON service boards: GPBD, GPFD etc.

Software: generally has been installed inside the control board SCUN

Control board – SCUN (SCUL, SCUK, SCUH)

Function:

  • Systematic control, switching and unified network management
  • Simple routing protocol functions realization

External Interface:

  • CON (RS-232 the serial port maintenance)
  • ETH (10/100M Base-T the Ethernet port maintenance)
  • ESC environmental monitoring port
  • 4 GE uplink optical interfaces

Frequently configure two, one for main and one for standby, OLT software is installed in the main control board

GPON service board -GPBC/GPBD/GPFD

Main functions:

Huawei GPON (Gigabit Passive Optical Network) access panel and terminal ONU (Optical Network Unit) devices together to achieve the OLT function on GPON system, default with B + SFP module (free), to replace the need to purchase C +

Differences of GPON board:

Type Port number Optical module Maximum splitting ratio Traffic shaping
1G-GPON 4 SFF(Class B+) 1:64 No
1G-GPON 8 SFP(Class B+ and Class C+) 1:128 No
1G-GPON 8 SFP(Class B+ and Class C+) 1:128 Yes
1G-GPON 16 SFP(Class B+ and Class C+) 1:128 Yes
1G-GPON 8 SFP(Class B+ and Class C+) 1:128 Yes
10G-GPON 4 XFP 1:128 Yes

Difference between GPON intermediate B + and C + optical modules

  • Both of the B + and C + are supported 1:128 spectroscopic, mainly affecting transmission distance
  • The higher splitting ratio is, the greater of the loss, and the shorter of the transmission distance

Difference between GPON intermediate B + and C + optical modules

 Power board

  • MA5680T, MA5683T, MA5600T, MA5603T power only supports DC (If you only AC input, you need to buy an inverter to convert AC-48V into DC.)
  • MA5608T, divided into two kinds, AC and DC.

Software

  • The charges is based on each GPON port, from R (n) to R (n +1)
  • Software issues related to compatibility between Huawei OLT and Huawei ONT, with some compatibility version is better, and some relatively poor.
