10G SFP+ from Professional China Manufacturer
With the increasing requirements for data center expansion and scalability, how to realize the smooth evolution of data center from 40G/100G to 400G becomes a problem, improving competitiveness becomes cabling and even facilities must achieve reliability, manageability and flexibility.
Fiber connectivity solutions enable data centers to meet current and future data transfer rates. Traditional 10G often use SFP and optical module, two-core LC interface interconnection, 40G Ethernet specification requires 8 core interconnection, 4 rounds 4, using 12-core fiber optic cable cabling solution, each channel has 4 dedicated transmission fiber and 4 dedicated receiving fiber, the middle 4 fibers remain idle. The 100G Ethernet common solution provides for the use of 24 fiber optics, divided into two 12-core arrays, one array dedicated to emission, the other array dedicated to receiving, 10 fibers in the middle of each array for transmission of traffic, and 2 fibers idle at both ends. In traditional serial transmission, data is transmitted through a pair of fiber optics, one fiber emission (Tx) one fiber receiving (Rx). The choice of transceivers is not critical at 1G and 10G transmission speeds, as all transceivers operate in the same way and at the same wavelength. The choice of transceivers became even more critical as the network speed gradually increased to 40/100G, and the choice of transceivers became even more critical, as some transceivers used two different wavelengths and some transceivers used four different wavelengths.
This makes them not compatible with the SR4 protocol approved by IEEE using parallel optical transmission. Parallel optical transmission Uses parallel optical interfaces to simultaneously transmit and accept data on multiple optical fibers and is typically used for medium- and short-range transmissions. For parallel optical transmission, the 40G and 100G Ethernet interfaces have 4 x 10G channels and 4x25G channels, respectively, with 4 fibers per transmission direction. In other words, for 40G applications, the back end of the QSFP transceiver is connected to four 10G electrical signals, while four discrete 10G optical signals are transmitted and received from the front end of the transceiver via eight fibers.
This design allows a 40G transceiver to be used as both as a discrete 10G link and as a 40G link. In MPO-based cabling systems, upgrading from 1G to 10G, 40G, 100G or even 400G is very easy. Start with 10G, deploy an MPO backbone fiber optic cable between two 10G switches, and deploy a pre-end module or MPO panel to connect an LC jumper or MPO-to-LC branch jumper on one end of the switch.
When you need to upgrade the switch, simply replace the MPO/LC module box with the MPO adapter panel and connect the 40G/100G switch using the MPO jumper to complete the upgrade. Port branch deployment is driving the industry’s need for parallel optical transceivers. Today, 40/100G parallel optical transceivers are often used to decombine 40/100G parallel transceivers into four 10/25G links. Branch parallel optical ports are beneficial for many applications, including the creation of large-scale Spine-and-leaf networks and the implementation of high-density 10/25G networks. High density: The SFP plus switch board slab sits usually provides up to 48 ports, but now has 36 port QSFP switches, bringing the number of 144 10G ports for a single board; Today, many enterprise data centers still use 10Gbps transmission rates for cabling systems.
Although 100G/200G/400G technology and related products are booming, for some small and medium-sized enterprises, 10Gbps can meet the enterprise network transmission rate, but also to save costs for enterprises. Huihongfiber make the 10G SFP+, 25G SF28, 40G QSFP+, 100G QSFP28, AOC, DAC, transceivers, MPO/MTP cables, for your data center needs.
