FA-TCSGUS49-20BI, Industrial 1310nm/1490nm GPON ONU B+ SFP Optical
Transceiver Single Fiber SC
The working temperature of optical transceiver will affect the
parameters of the whole fiber optic transceiver. When the
temperature of the application environment changes, the current of
the optical transceiver will change with temperature, at the same
time will lead to parameters change of the fiber optic transceiver,
thus affecting the normal transmission work of the whole optical
transceiver, so how to control the problem? In fact fiber optic
transceiver can be with different defined temperature, as for
standard fiber optic transceiver, the default temperature is 0~70℃,
it is the most common one in the market, Fiberall also provide
industrial optical transceiver which is for relatively harsh
environment which is with very large working temperature range, the
defined temperature range of the industrial optical transceiver is
So, how to realize such a basic requirement of the industrial
optical transceiver? Fiberall guarantee the stability of industrial
fiber optic transceiver from the following points:
1, Hardware requirements: the IC (chip), TO CAN (laser) must meet
the industrial temperature level.
2, Physical cooling: maybe most practitioners have had this
experience when they were young. When you have a high fever, your
parents will put a cool sticker on your forehead, which is physical
cooling. so, in optical transceiver, the heat dissipation silica
gel is used for physical cooling, which is to let heat of TO out as
soon as possible. So you'll ask, what we will do if it's low
temperature? Isn't that a bit of a shield? Please check the
technology as below.
3, Temperature compensation: the role of temperature compensation
is to control the stable working current of the optical module.
When the temperature changes, the temperature compensation software
will play its role.
Temperature compensation will take long time, with increased or
decreased by 5 degrees (or 10 degrees) for a node to calculate its
slope, to get the results and then write into the corresponding IC
(chip) of the optical transceiver, to finish this work, our
technical staff at least have to stay in the high/low temperature
aging container for a few hours or even longer. This long time work
will increase the cost of raw materials and manufacturing and it is
the reason for high price of industrial fiber optic transceiver.

Main Characteristics Of GPON ONU SFP Optical Transceiver
1, The GPON optical transceiver integrates both the bidirectional
optical transceiver function and the GPON MAC function. The
downlink rate and uplink rate of the GPON is asymmetrical, the
uplink rate is 1.244Gbps and downlink rate is 2.488 Gbps and does
not require a single power supply.
2, It supports complex ONT management systems, including alarms,
configuration of DHCP and IGMP, and independent IPTV solutions.
3, The GPON ONU fiber optic transceiver can use G.988 OMCI GPON
4, It can be seamlessly integrated into the existing communication
equipment, and the GPON solution greatly reduces the installation
cost of fiber to the household.
