In the ever-evolving landscape of high-speed data transmission, the 100G BIDI 80KM optical module stands out as a crucial component, enabling efficient and long-distance data transfer. This ultimate guide will delve into the details of this advanced module, exploring its key features, specifications, applications, and the manufacturer behind it.

Understanding the Basics
The 100G BIDI QSFP28 80KM optical module, such as the unViso UGQ1HE8B model, is designed to meet the demands of high-performance data communication. BIDI, which stands for Bidirectional, allows data transmission and reception over a single fiber, making it a cost-effective and space-saving solution compared to traditional modules that require separate fibers for transmit and receive. This module is part of the extensive product lineup from UNIVISO, a professional manufacturer of optical transceivers established in 2011.

Core Technical Specifications
Let's take a closer look at the essential technical parameters that define this module:
  • Max Data Rate: It supports a maximum data rate of 103.12Gbps (4x 25.78Gbps). This high data rate ensures that large volumes of data can be transmitted quickly and efficiently, meeting the needs of bandwidth-intensive applications.

  • Max Cable Distance: With a maximum transmission distance of 80km over G.652 single-mode fiber (SMF) when used with RS(528,514)FEC, this module is ideal for long-haul communication links. Whether it's connecting data centers across cities or enabling communication between remote offices, this distance capability is a significant advantage.

  • Wavelength: The module operates at specific wavelengths for transmission and reception, with Tx at 1273nm and Rx at 1310nm. This wavelength separation is crucial for bidirectional communication over a single fiber, as it prevents interference between the transmitted and received signals.

  • Connector: It features an LC connector, which is a common and widely used connector type in optical communication. The LC connector offers low insertion loss and high return loss, ensuring reliable signal transmission.

  • Number of Fibers: Thanks to its BIDI design, the module only requires 1 fiber for both transmission and reception. This reduces the number of fibers needed in the network, lowering installation and maintenance costs, as well as saving space in fiber optic cables and patch panels.

Key Features
The 100G BIDI 80KM optical module comes with a range of impressive features that enhance its performance and usability:
  • Hot-pluggable: It supports hot-pluggable functionality, meaning the module can be inserted or removed from a device without powering down the system. This feature is highly convenient for maintenance, upgrades, and troubleshooting, as it minimizes downtime and ensures continuous operation of the network.

  • Single +3.3V Power Supply: The module operates on a single +3.3V power supply, simplifying the power management design of the devices it's installed in. This reduces the complexity of the power infrastructure and makes integration easier.

  • Temperature Range: It can operate within a temperature range of 0 to 70°C. This wide temperature tolerance ensures that the module can function reliably in various environments, including data centers with controlled temperatures and outdoor installations where temperature fluctuations may be more significant.

  • Power Consumption: With a maximum power consumption of 5.0w, the module is energy-efficient. Lower power consumption not only reduces operational costs but also helps in managing heat dissipation, which is crucial for maintaining the stability and longevity of the module and the devices it's part of.

  • DDM/DOM Function: The module includes a Digital Diagnostic Monitoring (DDM) or Digital Optical Monitoring (DOM) function. This allows real-time monitoring of various parameters such as optical power, temperature, voltage, and current. Network administrators can use this data to proactively identify and address potential issues, ensuring optimal performance and preventing network outages.

  • Compatibility with RoHS2.0: It is compatible with RoHS2.0, which is a set of regulations restricting the use of certain hazardous substances in electrical and electronic equipment. This compliance ensures that the module is environmentally friendly and safe for use.

Applications
The 100G BIDI 80KM optical module finds applications in various fields where high-speed, long-distance data transmission is required:
  • Ethernet Links: It is widely used in Ethernet networks to establish high-speed connections between switches, routers, servers, and other network devices. Whether it's within a large data center or between different data centers, this module enables fast and reliable data transfer, supporting the seamless operation of cloud computing, big data analytics, and other bandwidth-hungry services.

  • 100GBASE-ZR4lite: Specifically designed for 100GBASE-ZR4lite applications, the module provides a cost-effective solution for long-haul 100G Ethernet links. It meets the requirements of this standard, ensuring interoperability with other compliant devices and enabling the deployment of high-speed networks over extended distances.

Warranty and Quality Assurance
The module comes with a 3-year warranty, providing customers with peace of mind. This warranty coverage is a reflection of UNIVISO's confidence in the quality of their products, backed by their strong R&D, rigorous quality control, and rich production experience. The company's commitment to quality is further emphasized by their "Quality First" concept, ensuring that users receive a high-quality and reliable product.
