Note that special packaging designs can make these devices be athermal, so that no active temperature control is needed to maintain their stability with temper- ature changes.

When discussing couplers it is customary to refer to them in terms of the number of input ports and output ports on the device. The video traffic is sent independent of the ATM-encapsulated voice and data traffic. A protocol is a set of rules and conventions that governs the generation, formatting, control, exchange, and interpretation of information that is transmitted through a telecommunication network or that is stored in a database.

You should consult with a professional where appropriate.

Chapter 14 Network Management Functions. Ideally, a WiMax system can provide connectivity at speeds of up to 70 Mbps over distances as far as 30 miles. Both delays and variable losses of cells are possible. The designs include both keisrr and multichannel assemblies for cable-to-cable and cable-to-circuit card connections.

These factors also cause Applicationz to be distance sensitive. For downstream trans- missions, a PON uses a nm wavelength for combined voice and data traffic and a nm wavelength for video distribution.

Thus, the GPON standard describes the use of a secu- rity mechanism to ensure that users are allowed to view only the information intended for them. In Chapter 10 we give more details on the use of such cables in conjunction with subducts for Gred applications.

Standard SFP transceiver package. The document includes BPON surviv- ability architectures, protection performance criteria, and protection-switching criteria and protocols. An important ingredient of G.

At this point only half as much signal gerf is getting through fthx detector compared to lower frequencies. Allow additional time for delivery. This is due primarily to the large distance variations of customers from the central office.

The setup in Figure 5. Thus, in general, the ratio of the optical output at the bias point to that of a logic 1 level is around 0. The destination equipment is responsible for reassembling the fragments into the original packet format. The keisef transmission dis- tance depends on the optical splitter size 16 or 32 subscriber ports and on whether short-reach class B or long-reach class C optics are selected.

In addition, a key factor was to keep installation costs low, since an access network serves a limited number of users.

Encryption may be necessary to maintain privacy, since the downstream signal is broadcast and every ONT receives all the information destined for each end terminal. Assume that there are two optical power threshold levels in the Appilcations receiver. Concept of a loose-tube cable construction: Statistical multiplexing may be provided keoser make optimum use of network resources. To allow proper reception of the individual burst-mode frames, a certain amount of burst overhead is needed at the start of an ONT upstream burst.

The spectrum of electromagnetic EM radiation is shown in Figure 2.

Next, the book progresses from descriptions of PON and fiber-to-the-X FTTX alternatives to their application to fiber-to-the-premises FTTP networks and, lastly, to essential measurement and testing procedures for network installation applicationw maintenance.

Carlson, Communication Systems, 4th ed. Wiley also publishes its books in a variety of electronic formats. In the analysis above, we have assumed for simplicity that the device has no inter- nal loss. Therefore, when the receiver gets a CRC that is incorrect, the entire block of information bits is ignored.

General structure and functions of the seven-layer OSI reference model. For PON discussions we are concerned primarily with the lower three levels. Cross-sectional view of a fused-fiber concelts and its operation concept.

They have a low overhead, high coding gain, and can correct bursts of errors. There are several advantages to having the powering device indoors. This package provides the following: As shown in Figure 8.

Three different EFM physical transport schemes. The design and management of cables for the PON drop section are very important since they need to blend into the neighborhood environment, they must be easy to install, and they need to have high reliability to minimize costs for maintenance testing and troubleshooting procedures. In Chapter 8 we give details on this access scheme.

For such a case we can consider a simple geometric optics approach using the concept of light rays. For more information about Wiley products, visit our web site at www. Thus, the responsivity is a linear function of the optical power.

As noted in Table 6. The main drive behind new access technology devel- opments is to transition from slow traditional telephone lines to large-capacity links to allow users to have high-speed connections to outside networks. This process thus builds up the photon density in the gain region until lasing occurs. The stan- dards geed that deal with PON implementation schemes are introduced in Section 6.
