What is Fiber-to-the-______? FTTx , X มความหมายไดดงน FTTH – fiber to the home FTTP – fiber to the premise (both Home & Small Business) FTTU – fiber to the user FTTC – fiber to the curb/cabinet FTTB – fiber to the business
FTTx เปนชอของบรการ แบงเปน 2 ประเภทคอ 1. Direct Fiber เปนการใหบรการในลกษณะ P2P คอ ลากสาย fiber 1 core
ไปใหกบลกคารายเดยว 2. Share Fiber เปนการใหบรการในลกษณะ P2MP คอ ลากสาย fiber 1
core ไปใหกบลกคาหลายราย ซงแบงออกเปน 2 ประเภทคอ 2.1 Active Optical Network - ใชอปกรณทตองการกระแสไฟฟาในการ
ใหบรการ เชน Switch หรอ Router 2.2 Passive Optical Network - ใชอปกรณทไมตองการกระแสไฟฟาในการ

Active Components of a PON Optical Line Terminal (OLT),
Located at central office, Sends traffic to the splitter, Multiplexes voice and video for downstream transmission.
Optical Network Unit (ONU), Located near the customers location, Converts the signal from optical to the necessary traffic type,
Optical Network Terminal (ONT), Located at the customers location, Converts the signals from optical to the individual user ports,
Voice - Plain Old Telephone Service (POTS), RJ11, Video - 75 Ohm coaxial “F” connector, Ethernet – 10/100base T, RJ45.

GPON Interoperability
Many strong market drivers:– Facilitate competition, promote GPON as an open technology– Address various operators’ services (residential, business,
mobile backhaul…) in multi‐vendor environments– Enable business models where the retail service provider may
not operate the access network
GPON interoperability status– GPON Physical and TC layers fully tested and interoperable– OMCI layer now mature in standards (ITU‐T G.984 and G.988,
Broadband Forum TR‐156,TR‐167, TR‐142)– Broadband Forum “WT-255 GPON Interoperability Test Plan”– Operators now want a method to identify GPON equipment
that is fully standard compliant and interoperable

Remark: When Mobile Station switches to the other network, It has to acquire new IP address from new network. There will be an effect to the application that requires constant data transmission but for the application likes web browsing that doesn't always have an effect.We called this kind of switches network "loosely couple internetworking”.
