Description

What is a STB module ?

1 pair dropwire subscriber terminal block (STB) module without protection, gel filled, is a device used in telecommunications to facilitate the connection between external dropwire and internal wiring at a subscriber's premises. Here's a detailed look at its components and features:

• 1 Pair: Designed to handle a single pair of wires, typically used for connecting a telephone line or a data circuit.

• Dropwire: Refers to the cable that runs from the distribution point or telephone pole to the subscriber's premises.

• Subscriber Terminal Block (STB) Module: A type of terminal block used to terminate the dropwire and provide a connection point to the internal wiring.

• Without Protection: Indicates that the module does not include built-in surge or overvoltage protection.

• Gel Filled: The module contains a gel that provides environmental sealing to protect the connections from moisture and contaminants.




• It is a practical and efficient solution for terminating and connecting single pair telecommunications lines.

Main Features

• Environmental Protection:

  The gel filling protects the internal connections from moisture, dust, and other environmental contaminants, ensuring the reliability of the connection.

• Compact and Robust Design:

  The module is designed to be compact, making it suitable for installation in confined spaces. It is also built to withstand harsh environmental conditions, such as temperature variations and exposure to sunlight.

• Ease of Installation:

  Typically uses IDC (Insulation Displacement Connection) technology, which allows for quick and secure connections without the need to strip the insulation from the wires. This makes the installation process faster and more efficient.

• Durability:

  Constructed from durable materials that provide mechanical stability and long-term performance, even in outdoor or exposed locations.

• Reliable Connectivity:

  Ensures a stable and reliable connection for the transmission of telephone or data signals, minimizing the risk of connection failures.

• Cost-Effective:

  By omitting built-in protection features, these modules can be more cost-effective, making them suitable for use in environments where additional protection is not critical or where external protection devices are used.
  Its main features include environmental protection through gel filling, ease of installation with IDC technology, and robust construction for reliable performance in various settings. While it does not include built-in surge protection, it offers cost-effective and reliable connectivity for residential and commercial applications.

Technical Parameters

Working temperature: -45℃ ~ 60℃

Storage temperature: -50℃ ~65℃

Relative humidity: ≤85%(+30℃)

Atmospheric pressure: 70kPa ~106kPa

Appearance: the color of all metal and plastic parts is uniform, without any scratch, rust, crusting and cracks.

The labels are clear and complete.

Insulation resistance: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts ≥ 1000MΩ

Contact resistance between contacts: under normal ambient conditions, the contact resistance between contacts ≤7 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤3 mΩ And after inserting the connection cord (or test cord) into the module for 200 times, the increasing resistance ≤3 mΩ

Contact resistance between conductor and contact: under normal ambient conditions, the contact resistance between contacts ≤3 mΩ. After high temperature test, low temperature test, temperature varing test and humidity heat test, the increasing resistance ≤2 mΩ. And after terminating for 200 times, the increasing resistance ≤2 mΩ.

Dielectric strength: under normal ambient conditions, after high temperature test, low temperature test, temperature varing test and humidity heat test, the insulation resistance between any two independent contacts, and/or between contacts and metal parts is able to withstand an AC voltage of of 1000V (virtual value) at 45Hz~60Hz sinowave for 1 minute, without spark over and flying arc

Gas tight performance: contact touches the conductor at both sides, and thus forming the gas tight area, while the area of gas tight occupies ≥50% of the touched area on each side.

Conductor diameter range: 0.32mm-0.6mm, while insulation ≤ 1.4mm

Pulling strength:≥25N while pulling from the vertical side of the contacts

Flame retardant performance: all plastic parts are flame retardant, reaching grade of UL FV0

Life circle: ≥200 times
