Basic Layout of Huawei OLT
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
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.
