based on Microwave. The supervisor Engineer gives the idea as clear as possible at the given time. We only visit one connectivity room which is known as Mirroring Submarine Connectivity Room. This submarine cable is connected sequentially form Cox Bazar to Dhaka. The connectivity of this cable is shown below. In BTCL there are 5 STM-64 are used with speed of 10GB/s for each of them. Among them four STM-64 are NORTEL-6500 company and one is KT company. DWDM scheme is used in SDH-MUX system which

Pair - a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources. Fiber-Optics - a cable containing one or more optical fibers that are used to carry light. Coaxial Cables - a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Decibel - a logarithmic unit used to express the ratio between two values of a physical

between Copper and Fiber optic cables. We will discuss the differences between the two and why many of the current networks in operation use fiber on the backbone between equipment and telecommunications rooms or enclosures. Copper vs. Fiber In the comparison between fiber and copper fiber, costs of the fiber cable has come down quite a bit. The cable itself has become easier to install as well since the invention of the flexible fiber which makes it easier to pull the cable through places. The flexible

Fiber-Optic Cable: a cable with optical fibers coated with plastic. 5. Dark Fiber: an unused optic fiber coated with plastic layers. 6. Coaxial Cable: a transmission line for high-frequency signals. 7. Plenum: a type of electric wire cable laid in plenum spaces for building codes. 8. Riser: Cable that is run at non plenum spaces that is fire retardant. 9. Rip Cord: A parallel cord under the jackets of the cable to remove the jackets. 10. Core: The actual cable which conducts

These are Coaxial Cable, Twisted Pairs Cable, and Fiber Optics Cable. Twisted pair A pair of wires used in standard telephone wiring. They are twisted to reduce interference caused by the other twisted pairs in the same cable bundle. Twisted-pair wires go from homes and offices to the telephone company end office. Fiber-optic cable A transmission medium that uses glass or plastic cable instead of copper wires. Coaxial cable An insulated

Pair - pair of copper wires twisted together with no electromagnetic shielding around them. Shielded Twisted-Pair - type of twisted pair cable in which the pairs are enclosed in outer braided shield. Fiber-Optic Cable - cable containing one or more optical fibers. Dark Fiber - unused fiber; a fiber containing on or more optical fibers. Coaxial Cable - single conductor surrounded by insulation and a layer of shielding so the two conductors share a single axis. Plenum - air handling space

with no electromagnetic shielded around them. Shielded Twisted Pair – a type of twisted-pair cable in which the pairs are enclosed in an outer braided shield, the individual pairs may be shielded as well. Fiber Optic Cable – a cable containing one or more optical fibers Dark Fiber – an unused fiber; a fiber carrying no light, Common when extra fiber capacity is installed Coaxial Cable – a cable that has a single conductor surrounded by insulation and then a layer of shielding that is also
