NOT FIBER READY/NOT IN DESIGN

Many are the times the technicians have said that the location is not fiber ready and can't connect you to home fibre.

What shows it is fiber ready

1.If it's an sdu(single dwelling unit) There need to be a termination box near your house approximately not more than 150m.

2.For an sdu to be fiber ready also has to be in design, during survey your house need to be captured in the design

3.For a Mdu(multiple dwelling unit) there need to be an FAT inside the premises,an mdu cannot be connected from an outdoor FAT(usually mounted on a pole)

An SFP (Small Form-Factor Pluggable) module is a compact, hot-swappable transceiver that plugs into network devices like switches and routers, acting as an interface for different network connections, typically converting electrical signals to optical (fiber) or copper (Ethernet) signals for high-speed data transmission, offering flexibility for various distances and media types. They provide modularity, allowing ports to be configured for copper or fiber (single-mode/multi-mode) as needed, supporting speeds from 100Mbps to Gigabit Ethernet and beyond.
Key Functions & Features
Media Conversion: Translates signals between network devices and different cable types (fiber optic or copper Ethernet).
Hot-Swappable: Can be inserted or removed from a live device without shutting it down, maximizing uptime.
Media Flexibility: Allows network administrators to choose the appropriate transceiver (e.g., short-range fiber, long-range fiber, copper) for each port.
Supports Various Standards: Used for Gigabit Ethernet, Fibre Channel, SONET, and more, handling speeds up to 1Gbps (SFP) and higher (SFP+, QSFP).

Network latency is the delay in data transfer across a network, the time it takes for a data packet to travel from source to destination, measured in milliseconds (ms). High latency means lag and slow performance (bad for gaming, video calls), while low latency means fast, responsive communication (good for real-time apps). It's caused by physical distance, network congestion, hardware, and processing, and minimizing it is key for good user experience and efficient operations.
Key Aspects of Latency
Measurement: Usually measured in milliseconds (ms) using tools like ping, often as Round-Trip Time (RTT).
Impact: Affects website loading, gaming responsiveness, video conferencing, and financial transactions.
Causes:
Propagation: Physical distance data travels.
Transmission: Time to push bits onto the network.
Processing: Routers/switches analyzing packets.
Network Congestion: Overloaded links or servers.
Low vs. High Latency: Low latency = fast/smooth; High latency = slow/laggy.
Latency vs. Bandwidth: Bandwidth is data volume, latency is delay; a high-bandwidth connection can still suffer from high latency.

GPON, or Gigabit Passive Optical Network, is a fiber-optic technology standard for delivering high-speed internet, TV, and voice services (triple-play) using a point-to-multipoint architecture, sharing a single fiber among multiple users via passive splitters for cost-efficiency. It offers speeds up to 2.5 Gbps downstream and 1.25 Gbps upstream, making it a popular choice for Fiber-to-the-Home (FTTH) and Fiber-to-the-Premises (FTTP) networks by connecting central Optical Line Terminals (OLTs) to customer Optical Network Terminals (ONTs/ONUs).
Key Aspects:
"Gigabit": Refers to its high data transmission speeds (Gbps).
"Passive": Means it uses passive optical splitters in the distribution network (ODN), which don't need power, reducing costs and complexity compared to active networks.
Architecture: A single fiber from the OLT splits to serve many users (e.g., 1:32 or 1:64 split), efficiently sharing bandwidth.
Services: Delivers data (Ethernet), voice (VoIP), and video over fiber, known as "triple-play".
Standards: Defined by the ITU-T G.984 series of standards.

A fiber optic joint closure (or splice closure/box) is a sealed enclosure that protects and manages the splicing (joining) points of fiber optic cables, providing mechanical strength, environmental sealing (water/dust proof), and organization for splicing, storage, and branching in aerial, buried, or duct installations, ensuring reliable signal transmission across various network applications.
Key Functions
Protection: Shields delicate fiber splices from moisture, dust, vibration, impact, and extreme temperatures.
Sealing: Uses mechanical or heat-shrink seals for robust environmental protection (e.g., IP66 rated).
Management: Provides organized trays and space for storing excess fiber and managing splices.
Cable Entry/Exit: Accommodates straight-through, branching, and drop cable connections with various port configurations.
Strength: Offers mechanical strength continuity, supporting cable pull-out and bending forces.

OLT, or Optical Line Terminal, is the central device in a fiber-optic network (like PON) that connects the service provider's core network to multiple customer locations, managing and distributing high-speed internet, voice, and video services using optical signals, essentially acting as the "brain" for delivering fiber to homes (FTTH). It converts electrical signals to optical signals for transmission over fiber, manages traffic, and controls end-user devices (ONTs/ONUs).

An optical splitter is a passive fiber optic device that divides a single light signal into multiple identical signals (or combines multiple signals into one), essential for PON (Passive Optical Networks) in Fiber-to-the-Home (FTTH) to serve many users from one fiber. It works by splitting light power, typically using PLC (Planar Lightwave Circuit) or FBT (Fused Biconical Taper) technology, with key performance factors being the splitter ratio (e.g., 1x2, 1x8) and insertion loss (signal weakening), crucial for network planning.
