According to the wavelength, there are SFP optical modules with 850nm/1310nm/1550nm/1490nm/1530nm or 1610nm. Wavelength 850nm is for SFP multi-mode, the transmission distance is below 2KM; wavelength 1310/1550nm is for single mode, the transmission distance is more than 2KM. SFP module with 1490 wavelength is single mode, generally used for long distance transmission.
Relatively 850nm/1310nm/1550nm three wavelengths than the other three kinds of cheaper price. According to the rate, SFP optical Read more [...]

Cisco XFP-10GB-LR optical module is XFP package, working at 10G data rate and 1310nm wavelength for 10km information transmission. When select the fiber transmission media, Cisco XFP-10GB-LR needs single mode fiber optics. This optical module has dual LC ports with DDM function.
Like other optical module, Cisco LR XFP optical transceiver can bare -40 ℃ to 85 ℃ working environment; and it only need 3.3V power supply.

What are the advantages of SFP + optical modules? 3 points mainly.
1, The Size and shape of SFP + module is more compact than the X2 and XFP 10G optical module (same size of SFP);
2, Strong compatible and versatility, can be interconnect with the 10G same type of XFP, X2, XENPAK optical module;
3, the cost price, SFP has more advantages than + 10G the same type of optical modules.
What are the similarities and differences between SFP and SFP + optical modules ? See below please.
1, the appearance,they Read more [...]
The composition of SFP optical module are: laser, including TOSA transmitter and receiver IC ROSA PCB, external fittings are: shell, base, PCBA, TAB, card buckle, unlock pieces, rubber plug, the other in order to identify the convenient, general with the color of the TAB to identify the parameters of the module type.
For example : a black ring pull multimode wavelength is 850nm; blue wavelength 1310nm module ; yellow is the wavelength of 1550nm module ; Purple is the wavelength of 1490nm module Read more [...]
The main purpose of SOPTO Blog is to introduce fiber optical products, such as PCI-E card, fiber optical patch cords, fiber media converter and transceiver.
In order to let everyone understand optical communication products, we provide many features, application and description of them in detail for all of you.
What’s more, we will introduce the FTTH solution in the near future.
