Fiber Access Network• Untuk memenuhi kebutuhan bandwidth yang terus
meningkat untuk berbagai layanan bagi pelanggan diperlukan penyediaan “new high-bandwidth access services”.
• Optical fiber access menyediakan bandwidth sampai beberapa gigabits per second (Gbps)—dan mungkin akan terus meningkat sejalan dengan kemajuan teknologi.
• Konfigurasi jaringan– All optical fiber access network
• Point to point (PTP) network• Passive/active optical network (PON/AON)
– FTTx• Struktur jaringan berdasarkan penentuan titik konversi sinyal
(perubahan dari optik ke twisted pair atau coaxial cable)

• Does not contain any electronics between the central office/headend switch and the customer-premises equipment
• The entire down stream bandwidth is transmitted to the power splitter and delivered to each subscriber
• The customer-premises equipment contains optical transceivers that switch on and off during the allocated time slots and select their content; this prevents them from accessing content not intended for them
• Each splitter typically splits a fiber into 16, 32, or 64 fibers, depending on the manufacturer, and several splitters can be aggregated in a single cabinet

• All subscriber content is transmitted to the aggregation switch and then distributed to the appropriate subscribers only
• At the switch, all content is converted from an optical signal to an electrical signal, separated from other content, and converted again to an optical signal and delivered appropriately over separate fibers to each destination
• Active networks have additional intelligence located closer to the subscriber that can reduce latency, flexibly add bandwidth, isolate faults, switch, schedule and queue traffic— and maximize bandwidth utilization between the switch aggregator and central office

Power Line Communication (PLC)
• Powerline Communication (PLC), also known as Broadband Over Powerline (BPL) is a technique for sending high speed data through existing powerline as transmission medium.
• PLC creates a high speed data communications network using the medium and low voltage electric distribution grids which connects consumers to the Internet through any electric socket in the consumers home.
• Powerline is the worlds largest existing wired infrastructure.
