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).
