Overview of CWDM Mux and DWDM Multiplexer

As the CWDM Mux/demux and DWDM mux/demux goods are playing an even more and more important role inside the data transmission field, today organic beef focus on the key options that come with CWDM mux and DWDM mux first.

As everybody knows, the CWDM Mux / demux module is based on dielectric thin-film technology designed for integration in low cost Metro and Access networks. These include applications such as fiber to the home, business or curb. The module enables 4 or 8 channels to be either combined (added) or separated (dropped). The fileters operate with a channel spacing of 20nm corresponding to standard CWDM wavelengths. CWDM Mux Demux module is a device to allow multiple optical signals at different wavelengths to pass through a single optical fiber strand. The common configuration of CWDM mux/demux module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux/demux module. 3 Single fiber or dual fiber connection for CWDM Mux/demux are available. FiberStore’s CWDM modules has low insertion loss, high channel isolation, flat passband. Additional filters, to enable cascading of devices, or addition of 1310nm or other wavelength, can also be included in the module.

The CWDM mux products always own these following features:

> Passive, no electric power required. (MTBF ca. 500 years)
> Low insertion loss
> Accepts any data rate and any protocol on any port up to 10 Gbps, also 40 Gbps (DPSK, DQPSK) and 100 Gbps (DPQPSK)
> Fully transparent at all data rates and protocols from T1 to 40 Gbps
> 1RU Rack-mount chassis Low profile modular design
> Simple to install, requires no configuration or maintenance
> Low-cost transceivers applicable, existing equipment can still be used
> ISO 9001 manufacturing facility

And for the DWDM, which represents Dense Wavelength Division Multiplexing was created to multiplex DWDM channels into one or two fibers. This sort of products could make the optimum usage of your existing fiber optic infrastructure in an ideal way. It puts multiple signals together and sends them simultaneously along a fiber, simply with transmissions happening at different wavelengths, and also this turns an individual fiber to the virtual equal of a handful of fibers. It is really a good and also the most reasonable solution to date that will meet our increasing desires of large data transmissions. And also by using the impressive DWDM technique, it will transmit greater than 40 connections of numerous standards, data rates or protocols more than one common fiber optic link. 

For the DWDM products, the DWDM mux products combine several data signals into one for transporting on the single fiber as the dwdm demux separate the signals into one for transporting on the single fiber as the dwdm mux products combine several data signals into one for transporting on the single fiber as the dwdm demux separate the signals on the opposite end. Each signal reaches a different wavelength, they cooperate with each other perfectly.

The common configuration of DWDM mux is 4, 8, 16 and 32 channels. These DWDM modules passively multiplex the optical signal outputs from 4 or maybe more electronic devices, send on them an 
individual optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices in the opposite end with the fiber optic link.

The DWDM mux products always own these following features:

> Low insertion loss and high isolation.

> Simple to install, requires no configuration, and disassembles easily to clean.

> Fully transparent at all data rates and protocols.

> Completely passive, no power required, no cooling and so on.

Understand Variety of Fiber Optic Cables and Components Basic Knowledge

1. FTTH fiber cable

FTTH (Fiber To The Home), by definition is an optical fiber directly to the home. Specifically, FTTH refers to the optical network unit (ONU) installed in the home user or business user, in addition to the optical access family FTTD (fiber to the desktop) closest to the users outside the optical access network application type.

There are five main advantages of FTTH:

. It is passive network, from the central office to the user, the intermediate can be done basically passive;

. Its bandwidth is relatively wide, long-distance carriers fits the way large-scale application;

. Because it is hosted on the fiber business, and there is no problem;

. Because of its relatively wide bandwidth, support for the agreement is more flexible;

. As technology advances, including point to point, 1.25G and FTTH way have developed a relatively complete function.

2. Indoor fiber cable

Indoor optical fiber cables are classified according to cable using the environment, as opposed to a outdoor fiber optic cable.

Indoor cable is made up of optical fiber (optical transmission medium) through a certain process and the formation of the cable. It is Mainly composed of optical fiber glass(glass as thin as a hair) and plastic protective sleeve and plastic sheath structure, fiber optic cable is not gold, silver, copper and aluminum and other metals usually no recovery value.

Indoor fiber optic cable is a certain amount of composition according to certain way cable heart, outsourcing jacket, and some also cover the outer sheath for optical signal transmission to achieve a communication line.

The tensile strength of the small indoor fiber optic cable, a protective layer is poor, but also more lightweight and economical. Indoor cable mainly used in building wiring, and connections 
between network devices.

3. Outdoor fiber optic cable

Outdoor fiber optic cable, used for outdoor optical cable. As opposed to a indoor optical fiber cable.

Outdoor cable is one of the optical transmission line. Consists of a certain number of optical fiber according to certain way cable, outsourcing has a sheath, some still coated outer sheath.

Outdoor fiber optic cable consists of an optical fiber glass (glass as thin as a hair) and plastic to protect casing and plastic coating, fiber optic cable is no gold, silver, copper, aluminum and other metal, there is no recycling value.

Outdoor fiber optic cable tensile strength greater than the thick protective layer, and is usually sheathed (i.e metal leather wrapped). Outdoor cables is mainly applied to buildings, and between the interconnection between remote networks.

4. Fiber Optic Patch Cord

Fiber optic patch cord used to make the link from the device to the jumper cables fiber optic cabling. Fiber jumper has a thicker layer of protection, commonly used in the connection between the optical and terminal box. The commonly used fiber optic jumper include: ST, LC, FC, SC type.

Main categories:

Single-mode fiber jumper (Single-mode Fiber): Average single-mode fiber jumper with yellow connector and protective sleeve blue; transmission distance is longer.

Multimode fiber jumper (Multi-modeFiber): General multimode fiber jumper in orange, and some in gray, fittings and protection applied beige or black; transmission distance is shorter.

5. Optical Fiber Coupler

Fiber coupler also known as fiber adapter, fiber coupler for connecting fiber optic connectors, couplers. According to fiber optic connector head selection models. According to the connection head structure can be divided into: FC, SC, ST, LC, MTRJ, MPO, MU, SMA, DDI, DIN4, D4, E2000 various froms.

6. Optical fiber terminal box

Optical cable terminal box (also known as fiber optic terminal box or cable box) is a small core fiber optic cable to connect with the terminal equipment, mainly used for cable ends fixed, cable and fiber pigtail splice and I containment and protection.

7. Fiber Fusion Splicer

Two fiber optic cable connection, fiber optic cable should butt up inside the fiber because fiber is like glass, must be refused on the two dedicated connectors, connector card and then put together, so that the optical signal can be passed.

Light in the optical fiber transmission loss can be created, the loss is mainly consist of optical fiber transmission loss and loss of fiber of welding joint. Fiber cable once order, the basic purpose of optical fiber transmission loss but also determined that the loss of fiber of welding joint is related to fiber itself and site construction. Efforts to reduce the loss of fiber of welding joint, can increase the fiber optic repeater amplification and transmission distance attenuation of optical fiber link margin.

How To Quickly Build Your Fiber Optic Network

What is the most consuming work in building a fiber optic network

There are two works are usually the largest line items in an fiber optic network installation budget: pulling the fiber optic cables and terminating or splicing the cables.

When pulling the fiber optic cables, you must comply with the minimum bending radius of the cable, prepare the cable ends with a pulling eye kit, and filling the conduit with lubricant to minimize the damage risk to the cables.

That’s not all, termination of the fiber optic cable can be a daunting task if you install a large fiber optic network. The time needed for different optical fiber cable termination is different. Therefore, the choice of the optical fiber cale is a key decision to reduce your fiber optic cable cost.

Loose tube gel-filled vs.tight buffered fiber optic cable

Choose the cable type is one of the biggest cost drivers in the cable terminal. There are two basic types of cable used for system installation:

1. Loose tube gel-filled cable

2. Tight buffered fiber optic breakout cables

Loose tube fiber optic cable

Traditionally, loose tube fiber optic cable has been used for outdoor long-haul links. Due to the fragile bare fibers and gel filling, which must be cleaned prior to termination, loose tube gel-filled cable is the most difficult to splice and terminate and also has the highest termination material costs.

Loose tube fiber cable type must normally be terminated or spliced close to the cable entryway of a building to switch to indoor-style cable, as it is generally incompatible with indoor fire codes.

Tight buffered fiber optic breakout cables

Tight buffered cables require less care to avoid damaging fibers when stripping back the cable. Each fiber is protected with its own 900 um diameter buffer structure, which is nearly four times the diameter and six times the thickness of the 250um coating.

This structure leads to the excellent performance of moisture and temperature of indoor outdoor cable tight buffer, lets them directly to terminate connector.

Tight buffered breakout fiber optic cable, has individual subcables within a primary outer cable sheath. This cable is the cable of choice for direct connectorization, as each fiber has its own aramid strength member for connector tie-off.

The connectorized subcables may be directly connected to equipment without fear of fiber damage of connector/fiber interface damage in most situations. Fiber optic breakout cable is by far the least expensive and easiest cable type to terminate and requires the least experience on the part of the installer.

Price comparision between two type of optical cables

Optical cable price is typically lower for breakout fiber cable than for loose tube cable when fiber counts are fairly low. Loose tube cables are lower in price for higher fiber counts. However, higher splicing and termination costs of loose tube cable over moderate-to-short lengths can far exceed the additional cost of tight-buffered cables.

The advantages of breakout fiber optic cable

A typical case in which termination costs dominate is an interbuilding (outdoor) cable entering a building where the required termination point of the cable is some distance from the building 
entryway, and it is necessary to switch from outdoor to indoor cable.

Outdoor loose tube gel-filled cable is typically required to be transitioned to indoor cable within 50 feet of the cable entry point to comply with fire codes. However, a tight-buffered indoor/outdoor cable can be used throughout the link, requiring no transitions at the building entryway.

FiberStore have many types of outdoor loose tube cables, such as All-Dielectric Loose Tube Cables, Gel-Filled Loose Tube Cables, Double-Jacket Loose Tube Cables, Central Loose Tube Cables. They offer the best protection in an outdoor environment.
