What Are the Impacts of Temperature on Optical Transceivers?

---

 

The working temperature of optical
transceivers affects all the parameters of optical transceivers. If the ambient
temperature of the optical transceiver changes, the operating current of the
optical transceiver will vary with temperature. At the same time, the
parameters of the optical transceivers change, which affects the normal
transmission of optical transceivers. Today, we mainly talk about the causes of
too high or too low temperature on optical transceivers and its impact.

 

What Is the Normal Temperature of
Optical transceivers?

Because the type and brand of the
optical transceiver are complicated, the temperature of modules corresponding
to different optical transceiver
temperature levels are different and the temperature specifications defined by
the supplier are different, whether the temperature of optical transceivers is
abnormal or not needs to be considered according to these factors. Before we
use the optical transceiver, it is best to check the vendor’s definition of the
temperature profile of the optical transceiver so as to reduce the number of
problems caused by abnormal optical transceiver temperature.

 

Three Reasons That Affect the
Temperature of Optical Transceivers

1. The Poor Quality and Workmanship

 

If you use the optical transceivers
with poor quality and workmanship, then the phenomenon of abnormal temperature
of the optical transceivers is more common. Because the function of such
optical transceivers is instable, heat dissipation is also relatively poor. In
order to reduce the temperature anomaly and unnecessary discard, we advise to
use the optical transceivers with better function, quality and workmanship.

 

2. The Harsh Application Environment

 

Optical transceiver operating
environment is in the data center, computer room or interchanger. If the
optical transceivers are used in other environments, the change of the ambient
temperature will inevitably change the temperature of the optical transceiver,
thereby affecting its optical power and optical sensitivity. If the application
environment of optical transceivers is harsh, then we advise to select the
optical transceivers with industrial temperature or extended temperature.

 

3. The Use of Second-hand Optical
Transceivers

 

The temperature of new optical
transceivers is usually at 0-70 ° C and many second-hand optical transceivers
are inaccessible. And the second-hand optical transceivers cannot operate
normally in high-temperature or low-temperature conditions. Therefore, we
advocate the use of new optical transceivers.

 

What Are the Impacts of High or Low
Temperature on Optical transceivers?

If the optical transceiver temperature
is too high or too low, it will affect the function of the optical transceiver
and make the communication data appear faulty. The optical transceivers will
alarm if its temperature isn’t in the normal range. If the optical transceivers
are in a bad situation, interchangers will send data continuously. The optical
transceivers will not send / receive data from the beginning until it is
recovered to normal operation.

 

1. The Impact of Too High Temperature
on Optical Transceivers:

 

If the operating temperature of optical
transceivers is too high, the optical power of optical transceivers will become
larger and the receiving signal will be faulty, and even the optical
transceiver will be burned. As a result, the optical transceivers cannot work
normally. In this case, DDM function should be added. You can select
temperature control system for real-time monitoring and compensation to ensure
that the optical transceiver extinction ratio and luminous power stable, to
ensure the normal operation of the optical communication system.

 

2. The Impact of Too Low Temperature on
Optical Transceivers:

 

Generally speaking, as long as optical
transceivers are not exposed to the harsh environment below 0℃, the temperature will not be too low. It is better not to use
the optical transceiver in the condition of too low temperature, as this may cause
the function of the optical transceiver to be unstable.
