How to guarantee the transmission distance of the optical module?

  • November 25. 2016
With the increasingly fierce competition in the optical communication market, the price of the optical module is irregular, such as Cisco, HUAWEI, H3C, Juniper, Brocade，Extreme etc. The price of these big brand module is very high, the market capacity of third party compatible module is increasing continuously.
Second-hand optical module also appears on the market, so the customers will be prohibitive because of the high price for the big brand. But worry about the second-hand goods will bring unnecessary trouble to the communication if low price, so these days whether it is online or offline customers, they asked a lot of similar questions: “ Must be high quality! Can guarantee transmission to 80km?

Market demand for prices continue to decline, but the quality control has been unable to reduce the standard, but can’t reduce the standard of the quality control, this is also a great opportunity for our third party compatible module. In order to eliminate customer concerns and give end customers more quality assurance, let’s see how to guarantee the transmission distance of the optical transceiver?

According to the data rate:
155M, 622M, 1.25G, 4G, 6G, 8G, 10G, 40G, 100G...
According to the transmission distance:
300m, 550m, 2km, 10km, 15km, 20km, 30km, 40km, 60km, 80km, 100km, 120km

According to the connector:

LC connector optical transceiver, SC connector optical transceiver, RJ45 connector optical transceiver



According to the fiber quantity:
Single fiber optical transceiver, dual fiber optical transceiver
According to the fiber type:
Single mode optical transceiver, multimode optical transceiver



Different transmission distances need to be tested by different meters of optical fiber, for example:
SFP SX --- 1.25G SFP 850nm MM 550m LC optical transceivers need to be tested by MM 50/125um 550m optical fiber.



Let’s see what actual distance optical fiber we have?



Do you think how about 120KM actual distance optical fiber? 40+80km=？ Estimated that you have guessed it?
Hope these sharing will be helpful for you! Fighting together!
