Basic Knowledge About Tube bundle

Tube bundle has a crush and tensile strength to protect fiber optic cable, flexibility, and ease to bend or fix inside of cabinet or closure. This article will provide some knowledge of tube bundles.
What is Tube Bundle?
A tube bundle is also known as a protected micro-duct. This type of duct comprises a number of micro ducts that are loosely or tightly packed together and jacketed, in much the same way as an optical cable without the fiber. One way or several ways micro ducts are made into tube bundles with outer sheathing based on a certain combination order, which can accommodate more pipeline resources within the limited space.
Tube Bundle Types
The tube bundle is divided into DB (direct bury) and DI(direct installation).
1. DB Tube Bundle: The outer sheath is rugged high-density polyethylene HDPE providing excellent protection from the physical environment. An Aluminum layer is added to provide additional strength (silicone-coated ducts, water-blocking tape, aluminum or fabric installed, two layers of sheath, tracer wire, and ripcords installed).
2. DI Tube Bundle: The micro ducts are surrounded by a layer of moisture-barrier metallic or non-metallic tape and a flexible sheath of black HDPE. DI ducts can be installed in pre-existing pipes or sub-ducts.
Features and Benefits
1. The outer diameter of the micro duct is from 5 to 18mm
2. The inner wall is a smooth structure with a silicon layer which can effectively reduce the friction coefficient of the inner wall
3. Can be used to enlarge the capacity of existing pipelines and realize the maximization of pipeline capacity
4. Crush and tensile strength
5. Convenient in construction, save time and the project cost

Applications
The tube bundle is surrounded by a single thin HDPE sheath. The design makes the tube bundle suitable for installation in outdoor direct buried or other existing ducts. In addition, tube bundle is used in FTTX networks.

Conclusion
Tube bundle is a great way of getting the most versatility out of your current empty duct system. It has good mechanical performance to provide adequate protection for fiber optic cable. Sun Telecom provides tube bundles to the global market.

The Ultimate Guide to Business Router

图片
The business router provides Internet access for home and office and often connects two or more computer networks. It helps to manage network bandwidth, segmentation, security, and routing policies. This article provides a complete guide to the business router. What is a Business Router? A router is a device that connects two or more network devices. It acts as a gateway between networks. It is an intelligent network device that reads the address in each data packet and then decides how to transmit it. The business router is a device used to manage many terabits of data flowing through and between internet service provider (ISP) networks. It is the largest and most powerful network router from the Internet backbone. A business router usually provides connections for typical home and office networks. Features and Benefits 1. The business router provides network, application, and security services on a single device 2. The business router provides hardware-based VPN access for r

400G ZR Coherent Pluggable Optics: Enable 400G for Next-Generation Data Center Interconnect (DCI) and Metro Network Solutions

图片
400G ZR coherent pluggable optics plays a vital role in enabling the next-generation data center to interconnect (DCI) and metro network solutions to meet the bandwidth requirements of today and tomorrow. It reduces the cost and complexity of high-bandwidth data center interconnects and promotes interoperability among optical module manufacturers and providers. This article provides some knowledge about 400G ZR. What is 400G ZR? 400G ZR or 400ZR is an interoperable standard that enables the transmission of multiple 400GE payloads over Data Center Interconnect (DCI) links up to 80/120km using dense wavelength division multiplexing (DWDM) and higher-order modulation(16 QAM). It aims to secure an affordable and long-term implementation based on single-carrier 400G using dual-polarization 16 QAM (16-state quadrature amplitude modulation) at approximately 60 gigabaud (Gbaud). How Does 400G ZR Work? 400G ZR is an interoperable networking Implementation Agreement (IA) released by the Op
