TNF1SL4D,SL4D,Huawei OSN 1800 TDM SL4D Board

Huawei OSN 1800 TDM SL4D Board TNF1SL4D Overview

TNF1SL4D:2xSTM-4 optical interface board.

The functional version of the SL4D is TNF1.

The TNF1SL4D is a TDM board, which can be used on the OSN equipment to receive and transmit two STM-4 optical signals.

The TNF1SL4D converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition

The TNF1SL4D converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

The TNF1SL4D receives/transmits 2xSTM-4 optical signals, performs O/E conversion for STM-4 optical signals, extracts and inserts overhead bytes, and reports alarms generated on the line.

The TNF1SL4D consists of an O/E conversion unit, an overhead processing unit, a logic control unit, and a clock unit.

The TNF1SL4D board occupies one slot.

Functions and features of the TNF1SL4D

Function and Feature	Board
Basic functions	Receives/Transmits 2xSTM-4 optical signals.
Optical port specifications	Provides S-4.1, L-4.1, and L-4.2 optical ports. The characteristics of all optical ports comply with ITU-T G.957. A STM-4 optical port can be a colored DWDM optical port. A colored DWDM optical port supports a transmission distance of 120 km.
Optical module specifications	Optical module information can be detected and queried. Single-fiber, bidirectional, pluggable optical modules can be used. Pluggable optical modules support hot swapping. Appropriate SFP optical modules can be used, their information can be queried, and their running status can be monitored. This facilitates your maintenance. Allows setting the on/off state of a laser and supports the automatic laser shutdown (ALS) function.
DCN	Supports outband DCN.
Service processing	Processes VC-12/VC-3/VC-4 services and VC-4-4c concatenated services.
Overhead processing	Processes the section overheads of STM-4 signals. Processes higher order path overheads. Provides transparent DCCs channels. Sets and queries J0, J1, and C2 bytes.
Pointer processing	Processes AU pointers.
Alarms and performance events	Provides various alarms and performance events, facilitating equipment management and maintenance.
Protection schemes	Supports two-fiber bidirectional ring MSP. Supports linear MSP. Supports SNCP.
