2. Drop (telecommunication) - Wikipedia

   en.wikipedia.org/wiki/Drop_(telecommunication)

   A drop can also be a wire or cable from a pole or cable terminus to a building, in which case it may be referred to as a downlead. These cables may be reinforced to withstand the tension (due to gravity and weather) of an aerial drop (i.e., hanging in air), as in "messenger" type RG-6 coaxial cable , which is reinforced with a steel messenger ...

3. Wavelength selective switching - Wikipedia

   en.wikipedia.org/wiki/Wavelength_Selective_Switching

   This provides cost and performance benefits for next generation colorless, directionless, contentionless (CDC) reconfigurable optical add-drop multiplexer (ROADM) networks, resulting from improved scalability of add/drop ports and removal of erbium-doped fiber amplifier (EDFA) arrays (which are required to overcome splitting losses in multicast ...

4. Telecommunications link - Wikipedia

   en.wikipedia.org/wiki/Telecommunications_link

   The reverse link (sometimes called a return channel) is the link from a mobile user to a fixed base station. If the link includes a communications relay satellite , the reverse link will consist of both an uplink (mobile station to satellite) and a downlink (satellite to base station) which together constitute a half hop .

5. Local loop - Wikipedia

   en.wikipedia.org/wiki/Local_loop

   Local Loop. In telephony, the local loop (also referred to as the local tail, subscriber line, or in the aggregate as the last mile) is the physical link or circuit that connects from the demarcation point of the customer premises to the edge of the common carrier or telecommunications service provider's network.

6. Optical Carrier transmission rates - Wikipedia

   en.wikipedia.org/wiki/Optical_Carrier...

   OC-3 is a network line with transmission data rate of up to 155.52 Mbit/s (payload: 148.608 Mbit/s; overhead: 6.912 Mbit/s, including path overhead) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 ( SDH ).

8. Optical add-drop multiplexer - Wikipedia

   en.wikipedia.org/wiki/Optical_add-drop_multiplexer

   Optical add-drop multiplexer, using a fiber Bragg grating and two circulators. An optical add-drop multiplexer ( OADM ) is a device used in wavelength-division multiplexing (WDM) systems for multiplexing and routing different channels of light into or out of a single-mode fiber (SMF).

9. Optical mesh network - Wikipedia

   en.wikipedia.org/wiki/Optical_mesh_network

   Switching, multiplexing, and grooming of traffic in an OEO device. Optical mesh networks refer to transport networks that are built directly off the mesh-like fiber infrastructure deployed in metropolitan, regional, national, or international (e.g., trans-oceanic) areas by deploying optical transport equipment that is capable of switching traffic (at the wavelength or sub-wavelength level ...
