Four evolutionary stage of optical network

Future trends optical networking should be further enhanced by network intelligence and automation to ensure a more accurate resource data, fault location more quickly and reduce the costs of maintenance personnel, thus achieving the purpose of reducing OPEX. Based on the current technical studies of the evolution of the optical fiber network should go through four stages.

Port intelligent. Automated data acquisition via fiber ports visualization and data to achieve more accurate optical network resources, the process is more optimized. Including electronic work order closed-loop operation, the port information is automatically collected and guidance of field operations and so on. This technique has started from 2011, it is also already gradually applied in the bearer network and access network outside of the fiber.

Link intelligent. Through centralized remote fiber test and performance data analysis, to achieve fast fault location, in order to protect the normal operation of fiber optic networks. Including analysis and other online OTDR monitoring to establish the link test, optical performance and network fault early warning mechanism for content, this technology research from 2014, there are some small-scale applications.

Node intelligent. The concept of intelligent peripherals to expand optical wiring nodes, thus completing the process from the point to the surface, and process optimization intelligent fiber optic network as a whole. Including environmental monitoring passive node has permission to manage passive electronic lock, you can trace the route covers the management of fiber optic lighting and fiber content on the route. This technology is expected to start in 2016.

Reconfigurable networks. The ultimate status of the fiber-based network should be an unmaintained network, automation technology will be fully applied in the fiber-based networks. Including user resources automatically assigned, remote device Automatic defibrillators, automatic routing failure repair. Fiber-based value-added features while sensing characteristics will emerge, such as energy, oil pipeline monitoring, electronic security fence program, based on optical fiber vibration of ammunition safety monitoring. At this time the fiber has not limited communication capabilities, but provides more room for imagination as other industry applications. This technology is expected to gradually start from 2018.

Select SFF small fiber optic connector of a few tricks

In the mature markets, the clear winner with excellent technology, and also to promote the continuous development of competing technologies. In the optical fiber interconnection market, this situation will appear in a small form factor optical connectors in the field. Over the past three decades, many of the optical connector blossom, as short-lived, and LC and MTP * / MPO interconnection system will emerge as the clear leader in the global scope enables users, system designers and The optical component and transceiver designers become beneficiaries.

LC connector can provide optimal performance and ease of use on ceramic sleeve connector. MTP / MPO interconnect interface between the optical properties of the fiber port concentration to make a certain balance with optimal density. Although the original SC connectors for low-density patch panels and light modules, FC connector is designed for a more robust environment test equipment. In most applications, in view of the obvious advantages LC and MTP / MPO connector, the amount of ST, SC and FC connector is declining.

LC fiber optic interconnect system can support a variety of diameters, strain relief boots or limit benders. LC tab can help to achieve maximum density patch panel, while maintaining the ease of use. For single-mode applications, APC (angle polish) version to help achieve excellent back reflection performance. LC connector optional six rotating bushing tuning, when needed to provide the lowest insertion loss performance.

Despite the need for more high fiber density, the solution is usually based on the requirements of the transition from the ceramic sleeve is connected directly to the Precision Mold, MT-based multi-fiber connector ferrule. This makes the situation increasingly complex. Now let's step back and explain terms:

● MT Barrel - Precision Mold casing can support 2-72 fiber, used as MTP / MPO fiber optic connector on the device

● guide pin - pin hole MT sleeve utilized a part of the organization, can provide precise function of the plurality of optical fibers between two paired MT casing

● MPO connector - Rectangular industry standard multi-fiber push-pull connector interface, the public side (with guide pins) / female side (no guide pin) configuration can accommodate MT casing

● MTP connector - The optical and mechanical properties and vendor-specific versions of the MPO as a trademark connector interface, especially after pairing with optical module can be improved optical interface

According to the number of rays and specific applications, MTP / MPO interface supports both multimode and single-mode optical fiber having different numbers of optical fiber, optical cable construction and the cable diameter. The optical performance of the interface from the MT ferrule Precision Mold technology and polishing of glass fiber, these two processes in the past few years have been a large degree of improvement. Singlemode MT angle polished casing through improved return loss performance, multimode sleeve is through PC (plane) polished. For specific optical modules MTP / MPO, such as QSFP (eight functional fiber, four central fiber is not used) or CXP (24 fibers), there are a series of standards to promote the growth of the number of optical fibers. The new standard will be 16 and 32 to make the definition of fiber optic version.

Compared with the connector based on LC ceramic sleeve, MTP / MPO fiber optic technology at the level of the number of ports per significantly improved density. However, this requires designers, installers and end users to manage fiber careful assessment, so that during the life of the cable infrastructure of moves, adds and changes.

Optical amplifier

Optical amplifiers are based on stimulated emission or stimulated scattering of incident light signal amplification principle to achieve a device. Optical amplifier in the structure is a smaller no feedback or feedback laser. Any optical media, when using the pump (electrical or optical) method, to be able to produce optical gain when the population inversion distribution that achieve optical amplification.

Current technology is relatively mature optical amplifier has an erbium doped fiber amplifier (EDFA), optical fiber Raman amplifier (FRA) and a semiconductor optical amplifier (SOA).

FTTH difficult five crux, light copper binding or a recipe

In March 2012 the Ministry of Industry has announced plans to achieve nationwide coverage FTTH 35 million households in the year, but a dream awake, "fiber to the home is difficult," "Broadband is not wide," the problem did not get solved. The implementation of the light to change so that Chinese netizens project was eagerly looking forward to, but the reality is cruel, slow process of reforming the unbearable, too many users expressed anger and dissatisfaction. China's broadband network construction shortcomings presented more worrying, rectification imminent. FTTH really that difficult? What is the reason? There is no solution?

Originally a technician can hold 10 ADSL broadband every day, the light changed only a day to complete two.

Fiber to the home, a stumbling block too much.

1, high-care costs, expensive charges, operators, equipment manufacturers, users tripartite coordination difficult;

2, property slotting allowance, the operator, the property is difficult to coordinate the two sides;

3, most of the building, the old district no internal embedded fiber optic lines, which makes the transformation more difficult and more time consuming to install;

4, after the light changed, fixed must be connected to the power supply, the power went out in a hurry very tangled;

5, some people need some people do not need, it is difficult unified, carrier pressure.

Of course, in China this population, the relationship between a complex environment, there will be this kind of problem, fiber to the home difficult, already reasonable.

Expert Weapon: "Light copper" Combined, hybrid deployment

Earlier reports said that, in addition to improving network speed through fiber transformation, utilizing copper technology also enables certain bandwidth of 12M, or 16M. There is also news that a foreign telecommunications equipment manufacturers announced last year new technology "VDSL2 Vectoring" has been achieved under the conditions of the use of copper, the family of bandwidth up to 100M.

In this regard, communications Standards Institute Ministry of Industry and Telecommunications Research Institute, deputy director Li Ao said that the current building is not embedded inside most of the fiber-optic lines, fiber to the home to a large scale, it means to be in an existing building internal re-laying of fiber optic cable. Fiber itself impatience tension and bending characteristics, determine the layout of the optical fiber is much more difficult than copper. He believes that "fiber + copper" combinations can be used as an important reference and select the current broadband construction.

The main factors of the fiber attenuation

The main factors causing the fiber attenuation: intrinsic, bending, extrusion, impurities, uneven and docking.

Intrinsic: inherent loss of optical fiber, including: Rayleigh scattering, intrinsic absorption.

Bend: the curved portion of the fiber within the fiber due to scattering of light is lost, resulting in losses.

Extrusion: produce slight bending the fiber squeeze caused by wear and tear.

Impurities: impurities absorb the optical fiber and the propagation of light scattering in the optical fiber, losses.

Uneven: the refractive index of the fiber material loss caused by uneven.

Docking: loss generated when optical docking, such as: different axes (single-mode fiber coaxial requirement is less than 0.8μm), the end face of the axis is not perpendicular to the end face of injustice, butt diameter does not match the heart and poor weld quality.

When the light incident from one end of the optical fiber, is emitted from the other end, the intensity of light will diminish. This means that the optical signal propagation through the optical fiber, optical attenuation part. This shows that the fiber has certain substances or for some reason, an optical signal through the barrier. This is the transmission loss of the optical fiber. Only reduce fiber loss, in order to make the optical signal unimpeded.

Italian operators to invest 6.4 billion euros to push fiber broadband plan

Recently, the three telecom operators in Italy Metroweb, Vodafone and Wind will launch cooperation disclose deployment of a national fiber optic network plan.

The national fiber optic network deployment plan will also have the intention to join other businesses open. But the three companies were not disclosed further information about the range of network construction, but also did not give a timetable. The companies said only in accordance with the ultra-fast broadband plans to build the network of the Italian Government.

In February this year, according to media reports that the Italian government is considering the introduction of a budget of up to 4 billion euros (about 28.331 billion yuan) of fiber stimulus plan, the latter may be an additional 2.4 billion euros, it aims to increase domestic fiber optic network coverage.

At present, the domestic fixed-line market in Italy is facing a variable. Vodafone and Telecom Italia are on the acquisition of Metroweb showed great interest, which has a 7200-kilometer fiber-optic network in Milan. Previously, Vodafone has tentatively been Fastweb lipped intent to acquire the latter. But Fastweb rejected Vodafone's offer. It is reported that, Metroweb being planned in 100 Italian cities to launch fiber.
