An Introduction of 4 Types of 100G QSFP28 Optical Transceivers

The continual rapid development of Internet and people’s desire for more high-speed optical networks promoted the development of the whole optical communication industry. Meanwhile, they strongly promoted the independent R&D and innovation breakthrough of many core technologies including optoelectronic devices technology. 100G optical transceivers are products of the big data era. According to authorities, by 2018, there will be 38% of service providers deploying 100G networks in the whole world, which means the 100G era has arrived.

Therefore, 100G optical transceivers are quite important in the optical networks, in which 100G QSFP28 optical transceivers are regarded as one of the most popular 100G optical transceivers in the current market. In the post, we will introduce you 4 types of 100G QSFP28 optical transceivers that may be helpful for your needs.

1. 100G QSFP28 CWDM4 2KM Optical Transceiver


100G QSFP28 CWDM4 2KM optical transceiver is a 100Gb/s transceiver module which is designed for optical communication applications compliant with the QSFP MSA,CWDM4 MSA and portions of IEEE P802.3bm standard. The optical transceiver module converts 4 input channels of 25Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. On the contrary, the module de-multiplexes a 100Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data on the receiver side. The product provides superior performance for 100G Ethernet applications up to 2km links.

2. 100G QSFP28 PSM4 2KM Optical Transceiver


100G QSFP28 PSM4 2KM optical transceiver is a four-channel, pluggable, parallel, fiber-optic QSFP28 PSM4 optical transceiver module for 100/40 Gigabit Ethernet and Infiniband DDR/EDR Applications. This optical transceiver integrates four data lanes in each direction with 104 Gbps bandwidth. Each lane can operate at 26Gbps up to 2km by using G.652 SMF. The optical transceiver module is designed to operate over single mode fiber system using a nominal wavelength of 1310nm. The electrical interface uses a 38PIN Edge type connector. The optical interface uses a single mode 12 fiber MTP (MPO) connector. The outstanding circuit and optical technology by Gigalight provide reliable long life, high performance, and consistent service.

3. 100G QSFP28 LR4 10KM Optical Transceiver


The 100G QSFP28 LR4 optical transceiver module is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard.
The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Its 100Gb/s high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet and OUT4 applications up to 10km links and compliant to optical interface with IEEE802.3ba 88 100GBASE-LR4 requirements. The product design and form factor, light/electrical connections and digital diagnostic interfaces are all based on QSFP+MSA protocol.

4. 100G QSFP28 SR4 Optical Transceiver


The 100G QSFP28 SR4 optical transceiver is a four-channel, pluggable, parallel, fiber-optic QSFP+ SR4 optical transceiver module for 100/40 Gigabit Ethernet, Infiniband DDR/EDR and 32GFC applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnects applications. It integrates 4 data lanes in each direction with 112.2 Gbps bandwidth. Each lane can operate at 8.055Gbps up to 70M using OM3 fiber or 100M using OM4 fiber. The module is designed to operate over multimode fiber system using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 12 fiber MTP (MPO) connector.


In above, 100G QSFP28 optical transceiver modules have huge market prospect that are better suited for high-density cabling and widely favored by most data centers.
