Have you ever wondered what holds us together you may not be able to see it but we feel its existence like an emotion a feeling a connection a bond that keeps us from falling apart bonds that shape everything from a grain of sand to the Gods of the universe these bonds enable us to reinvent our world

Presenting STL’s latest innovation in fiber optic cable. An intelligently bonded ribbon designed to navigate the complex web of networks with features that redefine the speed of network infrastructure creation.

How Unique is STL’s Celesta?

STLs Celesta intelligently designed smaller and denser optical fiber ribbon cable with its collapsible ribbon design. Celesta is 26 slimmer compared to a traditional loose tube cable with the same number of fibers. Its compact design allows for efficient duct space utilization and the cable can easily be blown inside a 20-millimeter duct innovative soothing design and non-preferential bending provide two times faster-blowing performance multiple peripheral strength members provide crush protection and rodent resistance celesta reduces cable installation time by up to 80 percent

How Celesta Achieves Lowest Attenuation in Ribbon Cables?

Its gel-free water blocking design enables faster cable end preparation and easy mid-span access color-coded bond design results in first time right splicing even with semi-skilled manpower operators can save up to eighty percent of splicing cost with five times faster ribbon splicing Celesta is made using STL’s G657A2 bend insensitive optical fiber which results in increased power budget and industry’s lowest attenuation in ribbon cables Celesta optimizes storage and shipping space owing to its lightweight and smaller form factor with Celesta network operators can reduce rollout time optimize duct space utilization reduce the size of passive network infrastructure and improves network performance STL’s celesta an intelligently bonded ribbon

Network operators are in a race against time to build future-ready optical fiber networks and winning this race would require a lot of innovation and a lot of optical fiber to help them win today and stay ahead tomorrow.


What is WiFi?

Put simply, WiFi is a technology that uses radio waves to create a wireless network through which devices like mobile phones, computers, printers, etc., connect to the internet. A wireless router is needed to establish a WiFi hotspot that people in its vicinity may use to access internet services. You’re sure to have encountered such a WiFi hotspot in houses, offices, restaurants, etc.

To get a little more technical, WiFi works by enabling a Wireless Local Area Network or WLAN that allows devices connected to it to exchange signals with the internet via a router. The frequencies of these signals are either 2.4 GHz or 5 GHz bandwidths. These frequencies are much higher than those transmitted to or by radios, mobile phones, and televisions since WiFi signals need to carry significantly higher amounts of data. The networking standards are variants of 802.11, of which there are several (802.11a, 802.11b, 801.11g, etc.).

What is an Optical Fibre Cable?

An optical fibre cable is a cable type that has a few to hundreds of optical fibres bundled together within a protective plastic coating. They help carry digital data in the form of light pulses across large distances at faster speeds. For this, they need to be installed or deployed either underground or aerially. Standalone fibres cannot be buried or hanged so fibres are bunched together as cables for the transmission of data. This is done to protect the fibre from stress, moisture, temperature changes and other externalities.

There are three main components of a optical fibre cable, core (It carries the light and is made of pure silicon dioxide (SiO2) with dopants such as germania, phosphorous pentoxide, or alumina to raise the refractive index; Typical glass cores range from as small as 3.7um up to 200um), Cladding (Cladding surrounds the core and has a lower refractive index than the core, it is also made from the same material as the core; 1% refractive index difference is maintained between the core and cladding; Two commonly used diameters are 125µm and 140µm) and Coating (Protective layer that absorbs shocks, physical damage and moisture; The outside diameter of the coating is typically either 250µm or 500µm; Commonly used material for coatings are acrylate,Silicone, carbon, and polyimide).

An optical fibre cable is made up of the following components: Optical fibres – ranging from one to many. Buffer tubes (with different settings), for protection and cushioning of the fibre. Water protection in the tubes – wet or dry. A central strength member (CSM) is the backbone of all cables. Armoured tapes for stranding to bunch the buffer tubes and strength members together. Sheathing or final covering to provide further protection.

The five main reasons that make this technology innovation disruptive are fast communication speed, infinite bandwidth & capacity, low interference, high tensile strength and secure communication. The major usescases of optical fibre cables include intenet connectivity, computer networking, surgery & dentistry, automotive industry, telephony, lighting & decorations, mechanical inspections, cable television, military applications and space.
