Does GPON use WDM?

Does GPON use WDM?

GPON utilizes both upstream and downstream data by means of Optical Wavelength Division Multiplexing (WDM). In downstream transmission, the lasers wavelength measures 1490 nm while the upstream wavelength measures 1550 nm. This transmission can reach up to 20 km starting from the central office running to the user.

Is GPON better?

GPON is better than EPON from the performance index. GPON is catching up and looking forward to the future broadband access market. GPON will be more suitable for customers with high bandwidth, multi-service, QoS and security requirements and ATM technology as the backbone.

What PON means in router?

Passive Optical Network
PON stands for Passive Optical Network. A PON system brings optical fiber cabling and signals all or most of the way from an Internet service provider (ISP) to the end user. A PON system is designed to deliver broadband Internet access to your home or office by connecting you as a subscriber to your ISP.

Why do we need GPON?

Its advantage is especially strong where minimizing maintenance work is important. The GPON design includes ATM encapsulation. This makes it convenient to deploy in networks which use an ATM backbone. A GPON can replace existing copper-wire cabling and deliver higher data speeds with greater reliability.

Is GPON outdated?

BPON, EPON, and GPON BPON networks are still around and will be for a long time, but they’re a previous generation of technology. BPON is slower than GPON and offers no advantages to compensate.

Which is faster EPON or GPON over PON?

EPON uses 1 gigabit per second upstream and downstream rates. It is a fast Ethernet over PONs which are point to multipoint to the premises (FTTP) or FTTH architecture in which single optical fiber is used to serve multiple premises or users.

What does GPON mean for passive optical network?

GPON replaces the traditional three-tier Ethernet design with a two-tier optic network by eliminating access and distribution Ethernet switches with passive optical devices. Cisco is introducing GPON with the Catalyst GPON platform. Gigabit-capable Passive Optical Network (GPON) – Standard for passive optical networks (PON) published by the ITU-T

What’s the difference between 10g Pon and G PON?

10G-PON (also known as XG-PON) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over existing dark fiber. This is the ITU-T’s next generation standard following on from G-PON or Gigabit-capable PON.

What does GPON stand for in Cisco Networking?

Background Information GPON is an alternative to Ethernet switching in campus networking. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network by eliminating access and distribution Ethernet switches with passive optical devices. Cisco is introducing GPON with the Catalyst GPON platform.
