With the continuous upgrading and development of the network, the sales of optical modules are constantly rising, and various types of optical modules emerge in an endless stream. Today, I will introduce the connection scheme of the conventional 10G SFP + optical module.

10G SFP+ optical module direct connection solution

①10G SFP+ SR optical module direct connection: two modules are connected by multimode optical fiber with LC interface, suitable for short-distance transmission within 300m;

②10G SFP+ LR optical module direct connection: two modules are connected through single-mode optical fiber of LC interface, suitable for 10 Gigabit Ethernet transmission within 300m to 10km

③10G SFP+ ER optical module direct connection: the two modules are connected through the single-mode optical fiber of the LC interface, which is suitable for transmission at a distance of 10km to 40km;

④10G SFP+ZR optical module direct connection: Two modules are connected through single-mode optical fiber of LC interface, which is suitable for long-distance transmission of more than 40km, and is currently the solution with the longest transmission distance of 10G optical modules.

10G SFP+ optical module and 40G QSFP+ optical module:

①Now the simplest SFP+ and QSFP+ connection scheme is to use a one-to-four jumper wire, one side is an MPO interface, and the other four are LC interfaces. The MPO interface is connected to the QSFP+ module, and the LC interface is connected to the SFP+ module without any equipment. It can be transmitted, which saves equipment and space resources. The disadvantage is that if one jumper is damaged, the whole one has to be replaced;

② There is another way to combine 4 SFP+ optical modules and 1 QSFP+ optical module with a fiber optic distribution box, and use an MTP-LC fiber jumper between the fiber optic distribution box and the QSFP+ optical module. The optical fiber distribution box and SFP+ optical module are completed through LC duplex jumpers. This solution can be easily maintained, and once one jumper is damaged, it can be replaced, saving jumper resources.

The mainstream 10G SFP+ optical module connection solutions are 10G SFP+ direct connection and 10G SFP+ and 40G QSFP+ interconnection. The above content includes the classification of these two major solutions.
