What is the difference between SFP+ and SFP
The difference between SFP+ and SFP. The pinout of SFP and SFP+ connectors are identical. However, SFP is data rate of 6Gb/s, whereas SFP+ is designed for 10Gb/s.
The SFP receptacles and plugs are not as well impedance matched as SFP+ receptacles and plugs.
Also SFP+ cable is designed for 10Gb/s whereas SFP cable may not be able to satisfactorily transmit that rate.
Sopto will release the leading products: short distance InfiniBand and QSFP + active optical cable (QSFP+ AOC) for Ethernet applications. The QSFP + active optical cable product has bright future in the industry. This QSFP+ AOC (Active Optical Cable) that designed and developed by Shenzhen Sopto Technology Co., Ltd. has been completed sample assessment and the first batch of products can release in April 2013. Sopto is the first to break the technological monopoly of foreign manufacturers and become one of the few local suppliers which can supply the product in bulk. QSFP + AOC active optical cable is an efficient integrated cable assembly that designed for application
The QSFP+ transceiver series are produced by Sopto for 40Gigabit Ethernet. The products of QSFP+ transceiver series include: SPT-QSFP+-SR4, SPT-QSFP+-LR4(40 GB/s QSFP+ LR4 10km Transceiver), SPT-QSFP+-IR4(40 GB/s QSFP+ IR4 2km Transceiver) and SPT-QSFP+AOCXXX(QSFP+ Active Optical Cable). Here, we will introduce SPT-QSFP+-SR4 for you. The 40 GB/s QSFP+ SR4 150m Transceiver is a parallel 40Gbps Quad Small Form-factor Pluggable (QSFP+) optical module. The transmission distance of SPT-QSFP+-SR4 is 150 meter. And the QSFP+ full-duplex optical module offers 4 independent transmit and receive channels, each capable of 10Gbps operation for an aggregate data rate of 40Gbps over 100
The advantage of fiber optical transceiver in optical network. The fiber optical transceiver converts the Ethernet data to the optical signal. With the optical multiplexing technology or other optical technology, it makes the sending signal and the receipt signal transmit in the same optical fiber. Therefore, it completes the bi-directional transmission of data in a single fiber and reaches the purpose of saving fiber optic. It is an economical and effective way to extend the transmission distance of data. When the Ethernet data is converted into optical fiber medium, the transmission distance can reach 60km, and can resist the electromagnetic interference at the
