1．PRODUCTION DESCRIPTION
1.1 Introduction
FWAP-1550H series EYDFA optical amplifier combiner is the latest equipment of optical
transmitting system for PON+CATV FTTH/FTTP. It realizes the combination function of OLT PON
and CATV 1550nm after optical signal is amplified. In detail, there is one way CATV input plus
16/32/64 routes PON signal in and the 16/32/64 routes which have 1490+1310+1550nm
combined output 1550nm with 30 to 45dBm total power. This equipment is well compatible to the
OLT/ONU of HUAWEI, ZTE, FiberHome etc and no data lost which owns high cost performance.
Ordinary erbium doped fiber amplifier (EDFA) has advantages of low noise, high gain, wider
bandwidth, high efficient pumping and stable operating, which is widely used in CATV system.
However, along with the implement of fiber to the house (FTTH), system C/N will be worse
significantly when EDFA uses as cascade amplification. Therefore, EDFA is required to produce
high saturation output power and low distortion as shown as 13dBm to 23dBm (approximate.
27dBm limited) for EDFA saturated output power. Moreover, the gain fiber of EDFA is single mode
and single packed fiber. Optic of pump is directly coupling into fiber but the diameter of fiber is very
small therefore it requires single mode of pump optic. Semiconductor of single mode only supports
hundreds milliwatt of output power and it is limited by the area of pump which makes high power
pump optic cannot be coupling. It consequently causes serious output power of optical laser. In
case, it develops double-cladding fiber internationally and solve the problem of listed weakness of
single packed fiber which improves 1 to 2 level for output power. It then drives the development of
high power optical amplifier. After several years’ research, our company overcome multiple
technical difficulties, high power ytterbium-erbium co-doped double-cladding fiber amplifier was
developed for CATV system to fit the requirement of FTTH and FTTB after conquer many
technical difficulty.
This serious product adopts JDSU,ⅡⅥ，LUMENTUM etc multimode high power pump laser
as pump source and American OFS closed beam splitter as double-cladding synthesizer. Built-in
stable optical power circuit and laser thermoelectricity freezer guarantees best performance and
long life cycle operating. Microprocessor software monitors operating status of laser which shows
on LCD. Once operating parameter of laser deviate from the range of set value, microprocessor
will cut power supply of laser automatically and red light turn will turn on with alarm (prompting
fault cause on LCD).Please refer to the following "Operation Instruction" for detailed report of
equipment parameters.
1.2 Features

1.2.3 Intuitive: Microprocessor monitors operating status of pump laser which is the most valuable
part of the equipment, operating parameters show on LCD display.
1.2.4 Network Management: Optional type status monitoring transponder certainly satisfy
national, SCTE, HMS, WEB standard, it realizes network management monitoring function.
1.2.5 Adjustable Output Power: The equipment is advanced designed which satisfies bigger
range of adjustment from lower to -2dBm (special offer).
1.2.6 High Power Output: Combined output power has maximum to 30~45dBm and multiple
output configuration is available for users requirement.
1.2.7 WDM Insertion: It is available to integrate FWDM module if user need which is convenient
when combines GPON, EPON,OEM:XG(S)-PON.
1.2.8 Connecting Safety Mode: To prevent the optical patch cord end face from being burnt when
the optical output is connected, enable this mode to reduce the output power direct to 19dBm
during connection. Once turn off this mode, it returns to the original set power.

7.OPTICAL CONNECTION ATTENTION
Before connection, clean all optical connectors carefully and read cleaning guide:
7.1 Optical Fiber Patch Cord
7.1.1 Taking off dust cap of fiber connector and making sure optical connector is APC
interface;
7.1.2 Using a specified dry wiping cloth without wool(5Kimwipes®) ; better to use specified
microscope (100 and 200 times) to check the clean level of optical connector or imperfection
statue;
7.1.3 Attention to keep connector clear and clean of flange plate, specified compressed gas to
clean the face of optical connector;
7.1.4 It is better to clean dust smaller than 0.2 micron;

8.1 The machine should have a good grounding, grounding resistance should be <4Ω. According
to international standards, 220V use three-wire system into the line, middle line is the grounding
wire.
8.2 This machine uses imported high-performance, highly reliable switching power supply with
constant voltage over-current protection, which already have imported fuse can be 165V ~ 260V
voltage range of the city within the network work properly. The machine's microprocessor output
DC voltage of the monitors, if the fuse blew, indicating failures have occurred inside the machine.
Therefore, the back panel of this machine has no 220V fuse.(The same as the imported
equipment).
8.3 In order to ensure the optical return loss ≥45dB, this machine optical connectors uses
SC/APC & SC/UPC.Connecting joints should be maintained clean. Plug should be used after
repeated ethanol and cotton wool to wipe the optical connector.
8.4 The input optical power of optical amplifier affect the system’s CNR, in practice, should be
based on indicators system, reference to " CNR degradation of the table " design the input optical
power of amplifier.
8.5 Optical fiber amplifiers work in the 1550nm wavelength, the max output optical power ≤
500mW. Access system in the machine, or optical output port unprotected pre-sets should not
open so as to avoid burns due to the optical connector, but also should prevent the laser direct the
human body, especially the eyes, causing harm to the people.
9. GUARANTEE AND MAINTENANCE MATTERS
9.1 Each optical transmitter has the company serial number (bar code). To the date of sale can
provide one-year.
9.2 The machine's microprocessor software with the laser working condition monitoring, digital
panel displays, fault alarm, network management functions. Non-human factors that can not be
damaged laser. If the machine flashes a red light appears (hint alarms), should be sent to the
company warranty. Users shall not open the lid for maintenance, otherwise the warranty
period,repairs and materials should be charged.
9.3 The warranty expires, providing life-long maintenance and equipment upgrades.
9.4 Due to power supply and man-made failures, resulting in damage to the device, are required to
