Huawei OSN 3500 OU08 N1OU08 N2OU08 SSN1OU08 Price

OSN 3500 is a new-generation optical transmission system developed by Huawei. It adopts a unified switching architecture and can function as an MPLS/MPLS-TP-based packet device or a TDM device. When working with other devices of Huawei, OSN 3500 supports various networking modes, including the pure packet mode, hybrid networking (packet + TDM) mode, and pure TDM mode, achieving optimal processing for packet services and traditional SDH services. Thus, OSN 3500 efficiently transmits voice and data services over the same platform.

Version Description

The OU08 is available in the following functional versions: N1 and N2. The difference between the two versions is with regard to the connector type for the optical/electrical interfaces and whether the optical/electrical module is swappable.

Table 1 describes the versions of the OU08.

Table 1 Versions of the OU08

Item	Description
Functional versions	The OU08 is available in two functional versions, namely, N1 and N2.
Common points	The working principle of the N1OU08 is the same as the working principle of the N2OU08.
Differences	The optical interface of the N1OU08 uses the LC connector, whereas the optical interface of the N2OU08 uses the SC connector. The N1OU08 uses the swappable optical/electrical module, whereas the N2OU08 does not use the swappable optical/electrical module. The N1OU08 supports optical power query when using pluggable optical modules, whereas the N2OU08 does not.
Substitution	None

Board Updates

This section describes the hardware updates in V200R013C30 and later versions as well as the reasons for the updates. Any product versions that are not listed in the document means that they have no hardware updates.

Application

The N1OU08 is an STM-1 optical/electrical interface board, and the N2OU08 is an STM-1 optical interface board. The OU08 can be used on the OptiX OSN equipment series to transmit and receive signals for the STM-1 optical processing board.

Functions and Features

The N1OU08 receives and transmits 8xSTM-1 optical/electrical signals, and the N2OU08 receives and transmits 8xSTM-1 optical signals. The OU08 must work with the SLH1 or SEP1.

Working Principle and Signal Flow

The OU08 consists of the interface module and power module.

Figure 1 shows the functional block diagram of the N1OU08/N2OU08.

Figure 1 Functional block diagram of the N1OU08/N2OU08

 NOTE:

N2OU08 boards receive and transmit 8xSTM-1 optical signals but do not receive or transmit electrical signals, whereas N1OU08 boards receive and transmit 8xSTM-1 optical and electrical signals.

Interface Module

In the receive direction, the interface module performs O/E conversion for STM-1 signals and transmits the signals to the SLH1 or SEP.

In the transmit direction, the interface module performs E/O conversion for STM-1 signals and transmits the signals to an optical/electrical interface.

 NOTE:

If an electrical module is installed, the interface module does not perform O/E conversion in both the receive and transmit directions.

Power Module

The power module provides all the modules of the OU08 with the required DC voltages.

Valid Slots

The slots valid for the OU08 vary with the cross-connect capacity of the subrack.

 NOTE:

The slots valid for a board are determined by the following factors:

• Slot bandwidth
• Cross-connect capacity
• Board version

• When the cross-connect capacity is 200 Gbit/s, the OU08 can be installed in slots 19-26 and 29-36.

Table 1 lists the slots valid for the SLH1 and the corresponding slots for the OU08. The OU08 installed in the slot with a smaller number transmits/receives the 1st to the 8th channels of STM-1 optical signals. The OU08 installed in the slot with a larger number transmits/receives the 9th to the 16th channels of STM-1 optical signals.
