You will wonder how to differentiate between a legal moving company and one that is not. From here we give you several guidelines for you to find out if you have all the guarantees to carry out your move in conditions.

Generally, all moving companies should have a web page where you can see where they are located, as well as various forms of contact (email, telephone, office addresses or storage). If the company that has passed your budget criteria but has no website you can start to distrust. Another of the parameters to take into account is to check reviews, the comments and opinions that this company receives on the internet (although many companies have several names for the same company of movers).

As for the budget, they will always have to go to the home to see in situ what furniture and equipment to move, as well as access to the building or your room, to be able to make a budget closed etc. Budgets by email without going to visit are unprofessional.

There are several factors, clues and differences that will make us suspect if a legal removal company is or is not. The first thing is to make sure that the removal company has a headquarters or physical offices, the second is that they have a fleet of properly labeled vehicles and the third is to sign a contract with the mover in which both the name of The moving company, as its location and tax data.

Once you have passed these 3 steps we can be sure that it is a legal moving company. In addition it will be advisable to see the opinions and comments that other private individuals have written about the removal company.

Over the last ten years, we have been seeing how pirate removal companies have proliferated exponentially, with what this entails. They do not have a company, they do not have physical offices and therefore they do not offer any type of insurance that can take care of any damage that could occur in our furniture and fixtures.

That is why we recommend that you choose Singapore movers, whether professional or self-employed, who have their physical existence and certificates and papers in order, this way you will save you scares and unpleasant surprises.

A good way to opt for one or another agency and know if it is a legal house moving service or not is going to their offices to sign the contract of moving, this way we know of a physical place where to be able to claim in case Necessary. Of course, in the contract, must appear all the furniture and equipment to be transferred, the packaging to be used, the length of the move, whether the company will add boxes or not, the price and payment methods and of course the compulsory insurance that every legal removal company should have.

Finally we must take into account that we should not only look at the net price of the move, but also the boxes, packaging, etc, we will charge the removal companies even if the naked eye is not seen in the budget.

Almost all modern optical transceivers use two fibers to transmit data between switches, firewalls, servers, routers, etc. The first fiber is dedicated to receiving data from network equipment, and the second fiber is dedicated to the transmission of data to the network equipment.

A new optical transceiver technology is now available and allows us to transmit and receive data from / to the interconnected equipment through a single optical fiber. This technology first emerged about 5 years ago and has led to the development of bi-directional transceivers, or BIDI transceivers for short.

How do BIDI transceivers work?

The main difference between bi-directional transceivers and traditional two- fiber optic transceivers is that bi-directional transceivers are equipped with Wavelength Division Multiplexing (WDM) couplers, also known as diplexers, which combine and separate the data transmitted through a single fiber Depending on the wavelengths of light. For this reason, bi-directional transceivers are also known as WDM transceivers.

To work effectively, two-way transceivers must be deployed in pairs, with their diplexers set to match the expected wavelength of the transmitter and receiver.

For example: If bi-directional paired transceivers are used to connect an A (Upstream) device and a B (Downstream) device, with transmission wavelengths 1310nm and reception 1490nm and vice versa:

The BIDI A transceiver must have a wavelength of 1490nm of transmission and a wavelength of 1310nm of reception.

The BIDI transceiver B must have a wavelength of 1310nm of transmission and a wavelength of 1490nm of reception.

The obvious advantage of using bi-directional transceivers is to reduce fiber cabling infrastructure costs by reducing the number of ports on the patch panel, which reduces the amount of tray space dedicated to fiber management, we mainly have two results, double the capacity of our network or reduce by half the cost of implementing a new network.

Online stores usually provide a full range of optical transceiver for all kinds of networking needs.

Due to the development of microelectronic technology, the technology of active and passive optical devices, optical transceiver has become a major general optical module in recent years. Although the optical module of the package, the cost, the transmission distance is different, but its internal composition is essentially the same. The main function is that the transmitting terminal device converts the electrical signal into an optical signal.

Optical module structure

The optical module includes optoelectronic devices, functions of the circuit and an optical interface and so on, optoelectronic devices, including transmit and receive.

Optical classification module

Optical receiving module, an optical transmission module and an optical transceiver, etc., may be divided into an optical module. The main function of the optical transceiver is implemented photovoltaic/electro optical conversion, including optical power control, modulation and transmission, signal detection and regeneration limiting function amplification solution. SFP, SFP +, GBIC, XFP, 1 x 9, etc. They are common. Cozlink glc sx mmd is one of the most popular optical transceiver module used in networking industry.
