100G QSFP28 Transceiver

100G optical transceiver has a transmission rate of 100Gbps, packaged in QSFP28. 100g transceiver has 4 independent optical signal transmission and reception channels, and the transmission rate of each channel is 25G. With the development of the optical industry centered on "100G network deployment", 100G optical modules have developed rapidly in the data center market.

As a professional 100g qsfp28 supplier and transceiver manufacturer, we also provide a variety of transceivers , for example,  400g transceiver, 40g transceiver, 25g transceiver, module sfp 10g, sfp transceiver, direct attach cable and active optical cable. Contact us to get 100g sfp price.

Different Types Of 100G QSFP28 Transceivers

Classification Of 100G QSFP28 Transceiver

100G optical modules can be divided into 100G SR4/100G LR4/100G CWDM4/100G ER4/100G PSM4 according to the transmission rate; divided into single-mode and multi-mode modules, and divided into 100m/2km/10km/30km/40km according to the transmission distance.

100G QSFP28 Transceiver FAQs

Q What Is The Range Of 100G QSFP28 Transceiver


The short-range qsfp28-sr4 transceiver supports up to 100 meters of connection through multimode fiber. This method is similar to using AOC cables, but structured cabling can be used here. They use more expensive non-standard MPO (multi push/pull cable) connectors, which offsets some of the cost savings of the transceiver.

The long-distance qsfp28-lr4 version supports up to 10km connection through single-mode fiber. They use standard LC connectors and use existing structured LC cabling.

Q How to use Gigabit optical transceiver and 10 Gigabit optical transceiver ?


Gigabit optical transceiver s are generally used on 1G ports, and 10 Gigabit optical transceiver s are generally used on 10G ports. Gigabit and 10 Gigabit optical transceiver s are relatively mature products now, and the cost performance is very high.

Q What is QSFP28 transceiver


QSFP28 optical module belongs to a mainstream 100G optical module in the market. It provides four different signal channels, and the transmission rate is increased from 40Gbps to 100Gbps. But the size of the QSFP28 optical module is smaller than the other 100G modules.

Q How To Use QSFP28 Transceiver For 100G Data Center Connectivity


The most direct way to connect 100g traffic is to use standard transceivers, and a variety of cables and transceivers are suitable for this.

In order to provide a cost-optimized solution to connect switches in racks or data centers, Ethernet switch suppliers want to maximize the density of optical transceiver ports on their equipment. In this way, they can provide the maximum number of channels and the lowest traffic cost per bit.

Most of these switch vendors choose the smallest shape transceiver: qsfp28 transceiver. It is the smallest module available and has the lowest power consumption among modules capable of handling 100g traffic. It is also worth noting that qsfp28 has the same physical size as qsfp + commonly used for 40g flow. This means that switch vendors can increase traffic throughput by 2.5 times without redesigning the front panel of their switches.

Q Where are 100G optical transceivers mainly used?


The 100G optical transceiver  is a high-speed optical transceiver , which is generally used in the core layer switch of the data center. The core layer of the data center has particularly high bandwidth requirements, and high-speed optical transceiver s are required to support services. 100G optical transceiver  is a very good choice.
