FA-TCQ40L4C-10, Four Channels CWDM QSFP+ LR4 40Gbps Optical Transceiver 10KM With LC Connector

40GBASE-SR4 and 40GBASE-LR4 are two basic interface standard of QSFP (QSFP+) Fiber Optic Transceiver (Optical Transceiver). The former is used in multi-mode applications, and the latter in single-mode applications.

40G BASE-LR4 QSFP+ Fiber Transceiver complies with 802.3ba (40GBASE-LR4) standard and it can work with LC fiber connector and the speed rate can reach 40Gbps. It has four data transmission channels and the data rate of each channel is about 10.3125Gbps so if the 4 channels work at the same time, it will realize the transmission requirement of 40Gbps.

40GBASE-LR4 QSFP+ fiber optic transceiver are commonly used between data centers and Internet switching points and it is always used with single mode fiber and the transmitting distance can reach 10Km.

40GBASE-SR4 QSFP+ is compliant with 802.3ba D3.2 (40GBASE-SR4) standard, it works with MPO/MTP fiber optic patch cord and realize 40Gbps connection. It also transmits via 4 channels and the speed rate is same as 40GBASE-LR4 QSFP+ fiber module. In data center, 40GBASE-SR4 QSFP+ works with MM OM3/OM4 fiber and reach 100m (OM3) and 150m (OM4) transmission so that it can realize the interconnection between two Ethernet switches.
