What
is the optical module, what types and functions are there？
First of all: what is the optical module?
The optical module is composed of
optoelectronic devices, functional circuits and optical interfaces. The
optoelectronic device includes two parts: transmitting and receiving.
Simply
put, the role of the optical module is photoelectric conversion. The
transmitting end converts the electrical signal into an optical signal. After
transmission through the optical fiber, the receiving end converts the optical
signal into an electrical signal.
The classification of different types of
optical modules differs greatly. So, what are the classifications of optical
modules? Generally, the classification of optical modules can be carried out
according to the following aspects:
1: Classification according to different
packaging forms;
2: Classification according to different
application fields;
3: Classification according to the
transmission rate of the optical module;
4: Classification according to compatible
brands;
5: According to the emission or reception
wavelength classification;
For example: the first type of
classification of optical modules: according to different packaging forms
If you know or read the naming of optical
modules, there are such words in the names of optical modules, such as sfp,
qsfp28, qsfp, cfp, xfp, etc. In fact, these are the packaging types of optical
modules.
Optical modules can be classified into the
following categories according to different packaging forms:
1. 1X9 packaged optical module
2. GBIC optical module
3. SFP optical module
4.XFP optical module
5.
SFP+ optical module
6. XPAK optical module
7. XENPAK optical module
8. X2 optical module
9. CFP optical module
Type: Single-mode optical module is
suitable for long-distance transmission; multi-mode optical module is suitable
for short-distance transmission.
Function: The optical module is used as the
carrier of the transmission between the switch and the device, which is more
efficient and safer than the transceiver.
