Huawei TMB3SL410

The Huawei TMB3SL410 is a 4-channel STM-1/STM-4 optical interface board in the Huawei OptiX OSN series of optical transmission equipment, mainly used for the access and processing of low-rate optical signals in the SDH (Synchronous Digital Hierarchy) network. The following is a collation of its detailed technical parameters:

1. Basic Functions and Features

• Type: 4-channel STM-1/STM-4 optical interface board (SL4 series).

• Main Functions:

  • Supports the access and processing of 4 channels of STM-1 (155Mbit/s) or STM-4 (622Mbit/s) optical signals.

  • Complies with the SDH/SONET standards and is compatible with ITU-T G.957/G.707 protocols.

  • Provides VC-12/VC-3/VC-4 concatenation and low-order/high-order cross-connection capabilities.

  • Supports 1+1 protection switching to enhance network reliability.

2. Interface Types

• Optical Interfaces:

  • STM-1 (155Mbit/s):

    • Supports optical modules such as S-1.1 (short distance, 2km), L-1.1 (long distance, 15km), and L-1.2 (long distance, 40km).

  • STM-4 (622Mbit/s):

    • Supports optical modules such as S-4.1 (short distance, 2km), L-4.1 (long distance, 15km), and L-4.2 (long distance, 40km).

• Interface Modes: Supports single-mode (SMF) and multi-mode (MMF) optical fibers (depending on the optical module model).

3. Hardware Specifications

• Dimensions: 25.4mm (width) × 235.2mm (depth) × 261.4mm (height).

• Weight: Approximately 0.8kg (there may be slight differences in different versions).

• Power Consumption:

  • The maximum power consumption is 25W (typical value) at room temperature (25°C).

4. Applicable Equipment and Slots

• Compatible Equipment:

  • Applicable to sub-racks such as OptiX OSN3500, OSN2500, and OSN1500.

• Available Slots:

  • Slot 1～4, 15～16** (bandwidth 1.25Gbit/s)

  • Slot 5～8, 11～14** (bandwidth 2.5Gbit/s).

5. Other Key Parameters

• Transmission Distance:

  • Short distance (2km), medium distance (15km), long distance (40km), depending on the optical module model.

• Protection Mechanisms: Supports SNCP (Subnetwork Connection Protection) and MSP (Multiplex Section Protection).

• Operating Temperature:

  • Commercial grade: 0°C～45°C

  • Industrial grade: -40°C～65°C
