P1501C1 and P1501C2.
1.1 Functionality and C aracteristics
EPON ONU series, according to t e meaning of t eir names, is ONUs
based on t e EPON tec nology. T ese ONUs provide t e i-speed Internet
access, online VOD, video conference and big-size file transmission. T eir
c aracteristics are described below:
 Hig speed: T e downlink or uplink transmission rate of t e uplink
port may reac 1Gbps, and eac client's port can support
bidirectional 100M data transmission.
 Easy maintenance: T e indicators s ow different statuses, w ic
elp to locate t e troubles.
 Long transmission distance: T e transmission distance can reac
up to 20KM.
 OAM: OAM is supported.
 CLI: CLI is supported.

Table 1-2 Description of interfaces and buttons
Interface/butto
n Function
LAN1~4/
LAN1~8/
T ey are Et ernet interfaces, w ic are used to connect a PC
or a switc .
PON It is t e SC connector of t e optical fiber, and can be
registered on OLT after connection.
ON/OFF It stands for t e switc of t e power source, w ic is used to
open or s ut down t e power source of ONU.
RESET
If t is RESET button is pressed for about 4 seconds,
P1501C1 will resume its original configuration and t en start
up again.

Interface/butto
n Function
POWER(PWR) It is used to connect t e interface of t e power adapter.
CONSOLE It is a serial interface wit RJ45 connector and used for
command-line management.
2 ONU Installation
T is c apter describes t e installation procedure before t e first usage of
ONU.
2.1 Application
2.1.1 FTTH
FTTH, representing Fiber To T e Home, means t at t e ONU is installed
at t e residential or office ome.
Optical Line Terminal (OLT) is laid at t e center of t e mac ine room,
w ile ONU, according to actual requirements, can be directly put at your ome
and its Et ernet interface provides connectivity. OLT and ONU in FTTH are
also connected in point-to-multipoint mode t roug t e optical splitter. For t e
detailed topology, see figure 2-1:
Figure 2-1 FTTH

5
2.1.2 FTTB
Fiber to T e Building (FTTB) is a broadband access mode based on t e
improved, i-speed and optical-fiber LAN. In t is access mode, t e optical
fiber is extended to t e building and t en t e network cable is deployed to eac
ome, so t is access mode is most reasonable, most practical and most
effective.
In FTTB, after OLT is put at t e center of t e mac ine room and ONU is
installed beside t e corridor switc , a networking layout for t e w ole building
s ould be conducted according to actual requirements. OLT and ONU in
FTTH are also connected in point-to-multipoint mode t roug t e optical
splitter. For t e detailed topology, see figure 2-2:
Figure 2-2 FTTB

6
Note:
ONU is suitable to be installed in t e ome or at t e corridor. Due to t e
complex of corridor-based installation and cabling, professional engineers are
required to conduct t e corresponding operations according to actual
requirements, and in t is case t e ome-based installation procedure, w ic
will be described in t is manual, is only for your reference.
2.2 Installation Preparation
T e computer must connect an Et ernet interface of ONU t roug
anot er Et ernet interface. So before ONU installation make sure t at t e
Et ernet card is installed on t e computer.
2.3 Connecting ONU
2.3.1 Connecting t e Network Cable
(1) Use one end of t e network cable to connect t e Et ernet port at
t e rear template of ONU.
(2) Use t e ot er end of network cable to connect t e Et ernet port of
t e computer.

2.3.2 Connecting t e Optical Fiber
Note:
 W en t e optical fiber is not used, make sure of wearing t e dust-proof cap
on t e optical interface of ONU and on t e optical fiber. By doing so, dust
and vapor can be prevented from contaminating t e optical fiber and t e
optical interface of ONU.
 Do not bind parallel optical fibers too tig tly so t at t e optical fibers can
be prevented from being dysfunctionally crus ed.
Before ONU connects t e optical fiber, you s ould get t e optical fiber
well installed. T e detailed procedure of installing t e optical fiber is s own
below:
(1) Screw off t e dust-proof cap.
(2) Connect t e connector of t e optical fiber to t e optical interface
on t e wall.
2.3.3 Connecting t e Power Adapter and t e Power Line
(1) Connect t e output terminal of t e power adapter to t e input
terminal of t e ONU’s power source.
(2) Insert t e ot er end of t e power line into t e socket of t e power
source.
(3) C eck w et er t e POWER (PWR) LED is on. If t e LED is
always on, it means t e power source runs normally; if not, please
c eck w et er t e connection between t e power line and t e
power adapter is correct.
2.3.4 C eckup After Installation
(1) C eck w et er t e LOS LED is on after ONU is powered. In case
t e LED is on, meaning t e received lig t is too poor, please c eck
w et er t e optical fiber is correctly connected.
