WE-1550-HT2 Outdoor 1550nm Optical Amplifier
1. Product Overview
The WE-1550-HT2 optical amplifier uses high-performance Er-Yb co-doped double-clad fiber and low noise pump laser. With
reliable circuit design and efficient heat dissipation it is able to operate in the temperature ranging from -30°C to +65°C that can
be applied in harsh outdoor environment. The equipment can be equipped with optical switch CWDM or RF detection to be
suitable for transmission of CATV RF signal and IP signal in FTTH network.
2. Performance C aracteristics
Adopt Er-Yb co-doped double-clad fiber.
8 16 or 32 output ports are optional.
Optional optical switch CWDM or RF detection.
Constant power mode or constant current mode can be set.
Support WEB network management.
Parameter monitoring of optical power and pump laser.
Fan alarm function and hot swap available.
Support hot swap of the air inlet dust screen.
Single or dual power supplies are optional and hot swap available.
Low noise figure: less than 5.5dB at 0dBm input.
Standard SNMP for remote control and management.
Operating temperature range: -30~ +65°C.

9. Attention
Insure the package is not defaced. If you think the equipment has been damaged please don't electrify to avoid worse
damage or do harm to the operator.
Before the equipment is power on make sure the housing and the power socket is reliably grounded. The grounding
resistance should be <4Ω so as to effectively protect against surges and static electricity.
Optical amplifier is professional equipment. Its installation and debugging must be operated by special technician. Read

this manual carefully before operating to avoid damage to equipment caused by fault operation or accident harm to the
operator.
While the optical transmitter is working or debugged there is an invisible laser beam from the optical output adapter on the
front panel. Avoiding permanent harm to the body and eye the optical output should not aim at the human body and
people should not look directly at the optical output with the naked eye!
The ventilation holes on the two sides shouldn’t be obstructed or the performance will reduce or the equipment will be
damaged in serve case.
When the fiber connector is not in use it should be put on the dust jacket to avoid dust pollution and keep the fiber tip
clean.
