Understanding 4 Types of 100G QSFP28 Optical Transceivers

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 4 100G QSFP28 optical transceivers full range of products.

1. QSFP28 100GBASE-CWDM4 2KM Optical Transceiver

100GBASE-CWDM4 QSFP28 optical transceiver is designed for optical communications applications that meet the QSFP MSA, CWDM4 MSA, and IEEE P802.3bm standards. This module converts 4 input channels of 25Gb / s electronic data into 4 CWDM optical signal channels and multiplexes them into a single channel for 100Gb / s optical transmission. Instead, at the receiving end, the module multiplexes 100 Gb / s optical input into 4 channels of the CWDM optical signal and converts it into electrical data for 4 output channels.

2. QSFP28 100GBASE-PSM4 2KM Optical Transceiver

100G QSFP28 PSM4 optical transceiver: GQM-SPO101-IR4C, four-channel parallel optical transmission, support 100G or 40G Ethernet, Infiniband DDR / EDR. It integrated four data channels for a total of 104 Gbps bandwidth, 26Gbps per channel, transmission distance of up to 2 km using G.652 SMF, the use of wavelength 1310nm for transmission. The electrical interface uses a 38PIN Edge connector. The optical interface uses a single-mode, 12-pin MTP (MPO) connector. Gigalight outstanding circuit technology and optical technology ensure long life modules, high performance and performance consistency.

3. QSFP28 100GBASE-LR4 10KM Optical Transceiver

Gigalight 100G QSFP28 LR4 single light module is compatible with 100Gbase-LR4IEEE 802.3ba standard and OUT4. The single receiver module supports only one 100Gb / s optical signal input 4-channel LAN WDM, and then convert them to 4-channel electrical signal output. The 4LAN-WDM channels at the center wavelength are 1295.56 nm, 1300.05 nm, 1304.58 and 1309.14 nm, in compliance with the IEEE 802.3ba protocol. The 100Gb / s high-sensitivity PIN receiver offers superior performance with support for 100G Ethernet and OUT4 applications with 10km links and meets the IEEE802.3ba 100Gbase-LR4 optical interface. Product design and packaging, optical / electrical connections and digital diagnostic interface are based on the QSFP + MSA protocol. It is designed to meet the toughest external operating conditions including temperature, humidity and EMI interference.

4: 100G QSFP28SR4 optical transceiver module

Gigalight Technology 100G QSFP28 SR4 optical transceiver module is a four-channel, pluggable, parallel, optical QSFP + SR4 100 or 40 Gigabit Ethernet, Infiniband FDR / EDR and 32GFC optical transceiver applications. This transceiver is a high-performance module for short-range multi-lane data communications and interconnects applications. It integrates four data lanes for each direction with 112.2 Gbps bandwidth. Up to 28.05 gbps per channel 70m Use OM3 fiber or 100m use OM4 fiber. These modules are designed to run on a multimode fiber using a nominal wavelength of 850 nm for the system. The electrical interface uses 38 contact edge type connectors. The optical interface uses 12 fiber optic MTP (MPO) connectors.
