G.652D fiber is one kind of single mode fiber, and is the mostly used fiber at present. This article will explain the difference of A B C D 4 types of G652 fiber, and their application from fiber attenuation and fiber dispersion.
Optical fiber is mainly divided into 7types: G651,G652, G653,G654,G655,G656,G657. This article mainly introduce one by one , and their characteristics, sub-categories and application.
G657 and G652 are both single mode fiber, but G657 fiber bend radius is 5-10mm, much smaller than G652D 30mm, and it is suitable for FTTH network, but G652D is idea in 1310nm wavelength.
This article explain what is combo port, and the problems may occur, and then discusses three solutions to improve the XG-PON resource utilization of the Combo user board. The solutions can be implemented independently or in combination.
XGS-PON, XG-PON are 10G GPON, upgrade version of GPON. XGS-PON uplink and downlink rate is 10G, XG-PON uplink 2.5G, downlink 10G, but GPON is uplink 1.25G, downlink is 2.5G.
This article mainly describe how to decide whether to update GPON to XGS-PON or XG-PON by upstream/downstream bandwidth utilization of the PON port through a comprasion of 2 cities.
fiber access network is to realize information transmission by optical fiber, it is mainly divide into 2types: active optical network and passive optical network. This article mainly brief introduction both and their advantages separately.
Currently, the focus of home broadband construction is gradually shifting from cities to rural areas. Since China Mobile’s own pole roads are relatively scarce in
FTTH access project mainly test the attenuation, include 4types: cable reel, splitter, optical link, and full process of optical distribution network.
Ecuador’s Claro is the first to launch a large-scale Light ODN solution in the international market. Currently, it has deployed 200,000 lines of FTTH networks,
When talking about user-side equipment in broadband optical fiber access, we often see English terms such as ONU, ONT, SFU, and HGU. What do
PON is the main technology used for fiber optic broadband access. It has been 15 years since China Telecom began large-scale commercial use in 2006,
