The OLT is located at the local end of the access network, which is
equivalent to a three-layer switch or router, and its function is
to provide an interface between the network side and the local
switch for the optical access network, and communicate with the ONU
of the user terminal through one or n ODN. The relationship between
OLT and ONU is the primary slave relationship. OLT separates
switching and non-switching services, manages signaling and
monitoring services from ONU, and provides maintenance and
assignment functions for ONU. A group of access links supported by
a transmission system, also known as a fibre loop system.
The core function of OLT
Include aggregate distribution and service processing function as
well as ODN adaptation functions. The aggregation distribution and
service processing functions process the information of different
services, including multiplexing / demultiplexing, switching /
interleaving, service quality control, bandwidth management, user
isolation, broadcasting and multicast, etc., the uplink is
connected with the service interface function, and the downlink is
connected with the ODN adaptation function. Wherein the
multiplexing / demultiplexing function is used for providing a
uniformly multiplexed information transmission channel for
transmitting and receiving various service flows in the ODN
direction, and the switching / interleaving function is used for
providing switching / interleaving capability for bandwidth
available at the ODN side of the OLT and bandwidth available at the
OLT network side; The service quality control function refers to
the control function of OLT resources and related service flows
required to ensure the QoS, security and other characteristics of
various services in the OLT service processing process; User
isolation and business isolation function is based on the user or
business type of traffic isolation measures taken to prevent the
user data privacy is damaged and business stolen; Broadcast and
multicast function refers to the OLT node to achieve
point-to-multipoint traffic transmission should support the
broadcast and multicast capabilities, in order to improve the
efficiency of bandwidth use.
Odn
The optical distribution network provides one or more optical
transmission channels between one OLT and one or more ONU, divided
into upstream and downstream directions. In the downstream
direction, the OLT transmits the service from the service node
interface to all ONU connected thereto by ODN broadcast. In the
upstream direction, the system adopts time division multiple access
technology to make ONU transmit information without collision to
OLT.
Onu
The role of ONU is to provide direct or remote user interface for
optical access network, to reuse and demultiplex the different
services of the corresponding user ( uplink direction will be
different home terminal different service signals multiplexed
together, in the same transmission channel transmission; The
downstream direction demultiplexes different services and sends the
services to the corresponding terminals through different
interfaces ), and is positioned at the user side of the ODN. An ONU
can connect a plurality of users, and the ONU terminates the
information from the ODN, processes the optical signal and provides
a service interface for a plurality of users. The network side is
an optical interface and the user side is an electrical interface,
so that the optical / electrical and electrical / optical
conversion functions are provided. Onu also completes the digital /
analog and analog / digital conversion, signal processing,
multiplexing and maintenance management functions of voice signals.
Gpon and EPON are both developed on the basis of a / bpon, and have
a common technical origin.
The difference between ITU and IEEE standards results in the difference between GPON and EPON in technical concepts:
Itu - t / fsan is an official communication industry standardization organization with the participation of operators. the standards set by ITU - t / fsan pay more attention to how the business needs of operators are realized and met.
Ieee is an electronic / electrical industry standard organization with the participation of engineers and equipment vendors. it pays more attention to the innovation and implementation of technology, but lacks the understanding and analysis of the actual needs of operators.

5 ) the client uses a home sfu terminal or a home gateway ( hgu )
based on pon uplink. General design does not carry out investment
budget, provided by the operation and maintenance and installation.
Ftth access is all-optical network access, network structure
evolved into four nodes a terminal.
Four nodes: integrated service convergence node ( OLT node ),
backbone fiber distribution point, wiring fiber distribution point,
building / floor fiber distribution point.
One terminal: the user-side home ONU or home gateway.

connection.
The first-level light splitting is mainly used for the construction
mode of new buildings.
Ftth access adopts a two-stage splitting mode, the first-stage
splitter is installed in the distribution optical crossover, and
the second-stage splitter is installed in the building / floor
shunt box. Wiring light intersection installation location:
high-rise building ( more than 64 households ), 1 building is
provided with 1 wiring light intersection, installed in the access
room / shaft; Multi - storey building will be more than one unit
building as a wiring area, wiring area user capacity is not less
than 64 households, the whole community should try to reduce the

The secondary light splitting is mainly used for the original
regional reconstruction and construction mode.
Selection of splitting method: for the newly-built community with signing intention, the capacity problem is mainly solved, the distance of using the incoming layer optical cable is short, the use of large-core optical cable has little influence on the investment, and the first-level splitting is preferred from the viewpoint of high utilization ratio of splitter ports, thereby reducing the occupation of trunk and OLT ports; For thin coverage area, the introduction of optical cable distance is long, large core number of cable use, will lead to greater investment increase angle consideration, should choose the secondary light splitting.
The differential classification of fiber optic transceivers is
divided by rate, and currently fiber optic transceivers can be
divided into 10 / 100 m adaptive fiber optic transceivers and 10 /
100 / 1000 m adaptive light
Fiber transceivers, pure gigabit fiber transceivers, 10 gigabit
fiber transceivers.
Pure gigabit transceiver products work at the physical layer, where
the transceiver products work by bit to forward data. This
forwarding mode has the advantages of fast forwarding speed, high
permeability, low delay and so on. it has good compatibility and
stability. it is suitable for the link with fixed rate. The 10 /
100 m fiber optic transceiver and the 10 / 100 / 1000 m fiber optic
transceiver operate at the data link layer, where the fiber optic
transceiver uses a store-and-forward mechanism that reads its
source MAC address and destination MAC address for each packet
received and forwards the packet out after the CRC cyclic
redundancy check is completed. The advantage of store-and-forward
is that it can prevent some erroneous frames from spreading in the
network, occupy valuable network resources, and prevent packet loss
due to network congestion. When the data link is saturated, store
and forward can put the data that can't be forwarded in the
transceiver's cache, waiting for the network idle before
forwarding. This reduces the possibility of data collision and
ensures the reliability of data transmission, so the optical fiber
transceiver is suitable for working on links with variable speed,
such as security monitoring, network data signal extension, etc.
Ten thousand trillion optical fiber transceiver is mainly used in
the photoelectric conversion of data room, the relative application
in the market at present
Less, only optical technology in China the company has to do ten
thousand trillion optical fiber transceiver.
By structure, it can be divided into desk-top ( stand - alone ) fiber-optic transceivers and rack-mounted fiber-optic transceivers.
A desk-top fiber optic transceiver is suitable for a single user,
such as meeting the uplink of a single switch in the corridor. Rack
fiber optic transceiver is suitable for multi-user convergence,
such as the center of the cell room must meet all the switches in
the cell uplink, use the rack to facilitate the unified management
of all modular fiber optic transceiver and unified power supply.
According to the fiber, can be divided into multimode fiber
transceiver and single-mode fiber transceiver. Because of the
different optical fibers used, transceivers can transmit at
different distances. multimode transceivers typically transmit
between 2 km and 5 km, while single-mode transceivers can cover
between 20 km and 120 km. It should be noted that the transmission
power, reception sensitivity and wavelength of use of the fiber
optic transceiver itself will vary depending on the transmission
distance. 5 km fiber optic transceiver transmission power is
generally between - 20 ~ - 14 db, receiving sensitivity of - 30 db,
using 1310 nm wavelength; The transmission power of 120 km optical
fiber transceiver is between - 5 ~ 0 db, the receiving sensitivity
is - 38 db, and the wavelength of 1550 nm is used. According to the
fiber interface, can be divided into single fiber optic
transceiver, dual fiber optic transceiver, SFP
Fiber optic transceiver.
Fiber optic transceiver.
As the name suggests, a single-fiber device can save half of the
fiber, i.e., receive and transmit data on one fiber, which is ideal
where fiber resources are tight. Wavelength division multiplexing (
WDM ) technology is used in this kind of products. the wavelengths
used are 1310 nm and 1550 nm. However, because of that lack of
uniform international standard for single-fiber transceiver
products, product from different manufacturers may exist when
interconnected
In the case of incompatibility. In addition, due to the use of wavelength division multiplexing, single fiber transceiver products generally have the characteristics of high signal attenuation. At present, most of the optical fiber transceivers on the market are dual-fiber products, which are mature and stable. The optical interface of SFP optical transceiver is determined by the optical fiber module. at present, SFP optical module has single fiber and double fiber in the market, which is widely used in the market.
According to the network management, can be divided into network management type optical fiber transceiver and non network management type optical fiber transceiver.

With the development of the network towards the direction of
operational and manageable, most operators hope that all the
equipment in their network can achieve the degree of remote network
management, fiber optic transceiver products and switches, routers
are also gradually developing in this direction. At present, most
of the vendor's network management systems are based on SNMP
network protocol development, support including web, telnet, CLI
and other management methods. The management content includes
configuring the operation mode of the fiber optic transceiver,
monitoring the module type, operation status, chassis temperature,
power supply status, output voltage and output optical power of the
fiber optic transceiver, etc. With the increasing demand for
equipment network management by operators, it is believed that the
network management of optical fiber transceiver will become more
practical and intelligent. There are fiber optic transceivers with
Poe and no Poe, depending on whether power is supplied or not
Fiber optic transceiver .
Fiber optic transceiver .
Poe fiber optic transceiver is widely used in the security industry
at present, the camera power supply, eliminates the trouble of
power supply, Poe transceiver power supply generally uses support
802.3 af and 802.3. at standard and non - standard, non-standard
Poe than the market standard Poe price difference is very big, but
cheap things must be hateful, non-standard Poe mandatory power
supply to the power receiving equipment, may cause equipment damage
due to excessive current. Gb Poe general electric confession
electric power in about 15 w - 50 w, according to the power of the
power receiving equipment ( PD ) can be customized, af standard in
15.4 w - 25 w, at standard in 30 w - 50 W..
