1G optical module refers to the optical module with a transmission rate of 1.25Gbps. The 1G optical module is already a very mature series of products, which are favored by the majority of users since its advantages of low power consumption, small size, long transmission distance, and low price.
SFP-1G-LX 1310 single-mode optical module is a widely used 1G optical module and its package type is SFP. The transmission rate is 1.25G, the center wavelength is 1310nm, and the transmission distance can reach 10km when used with single-mode fiber. 1G single-mode optical modules support hot-swappable and low loss. Following, I will introduce some basic knowledge of the SFP-1G-LX 1310 1G single-mode optical module.
Principle
1G single-mode works on the principle of photoelectric conversion. The Transmitter side converts the electrical signal into an optical signal, and after being transmitted through the optical fiber, the receiver side converts the optical signal into an electrical signal.
Transmitter Side: An electrical signal with a certain bit rate is input and processed by an internal driver chip to drive a semiconductor laser (LD) or a light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. It has an automatic optical power control circuit inside so that the output optical signal power remains steady.
Receiver Side: The optical signal with a certain bit rate is input into the module and converted into an electrical signal by the photodetector diode.
Executive Standard
- SFP MSA (INF-8074i)
- SFF-8472 v9.3
- IEEE802.3z Gigabit Ethernet
- ITU-T G.695
- FC-PI v2.0
Application
1G single mode can be adapted to a 1G optical port or 10 Gigabit optical port that can be backward compatible with the 1G. It is suitable for long-distance optical fiber transmission scenarios and is widely used in Gigabit Ethernet, Fiber Channels, and other optical fiber networks.
Whether you need to choose a 1G optical module in the application depends on the specific application scenario such as equipment type, fiber resource, transmission distance, etc. NADDOD has a wide range of product series and a complete after-sales system and is committed to providing high-quality optical transceiver products and providing personalized designs and solutions for the majority of users.
