by adminNov 5, 2019Industrial News

The continuous and rapid development of the Internet as well as the desire of people for higher speed optical networks promoted the vigorous development of the entire optical communications industry and the strong promotion of independent R & D and innovation in many core technologies including optoelectronic devices technologies that have also been accelerated. 100G optical transceiver is the product of this big data era.

Now according to authoritative statistics, by 2018, 38% of service providers worldwide will deploy 100G networks, which means the 100G era has come.

Therefore, 100G optical transceivers in the composition of the optical network play a pivotal role. So what are the 100G QSFP28 optical transceivers in the industry today? Today we will introduce 5 100G QSFP28 optical transceivers full range of products.

1. 100G QSFP28 CWDM4 2KM Optical Transceiver

100G QSFP28 CWDM4 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 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 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 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.

5. 100G QSFP28 ER4 Optical Transceiver

100G QSFP28 ER4 is a 100Gbps transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard. The module converts 4 input channels of 25Gbps electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gbps optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gbps optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data.

The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The high performance cooled LAN WDM EA-DFB transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 10km links and compliant to optical interface with IEEE802.3ba Clause 88 100GBASE-LR4 requirements.
