100G fiber optical module has a variety of packaging forms, including CFP/CFP2/CFP4, CXP and QSFP28. Among these different 100G fiber optical module packaging forms, the QSFP28 fiber optical module has become the main packaging method for 100G networks because of its advantages of high port density, low power consumption and low cost. Below we briefly introduce three common 100G fiber optical modules;
1.100GBASE QSFP28 LR4 Fiber Optical Module
100GBASE-LR4 QSFP28 fiber optical modules are generally used together with LC single-mode fiber patch cords, and the maximum transmission distance can reach 10km.
The 100GBASE-LR4 QSFP28 fiber optical module converts 4 channels of 25Gbps electrical signals into 4 channels of LAN WDM optical signals, and then multiplexes them into a single channel to realize 100G fiber optical transmission. At the receiving end, the fiber optical module demultiplexes 100G optical input into 4 LAN WDM optical signals, and then converts them into 4 electrical signal output channels.
The main features are as follows;
● Hot pluggable QSFP28 MSA form factor
● Compliant to IEEE 802.3ba 100GBASE-LR4
● Up to 10km reach for G.652 SMF
● Single +3.3V power supply
● Operating case temperature: 0~70℃
● Transmitter: cooled 4x25Gb/s LAN WDM EML TOSA (1295.56, 1300.05, 1304.58, 1309.14nm)
● Receiver: 4x25Gb/s PIN ROSA
● 4x28G Electrical Serial Interface (CEI-28G-VSR)
● Maximum power consumption 4.0W
● Duplex LC receptacle
2.100GBASE-SR4 QSFP28 Fiber Optical Module
The 100GBASE-SR4 QSFP28 fiber optical module is a parallel 100G fiber optical module. QSFP28 full-duplex fiber optical module provides 4 independent transmission and reception channels, each function can operate at 25Gbps at 100 meters of OM4 MMF, and the overall data rate is 100Gbps.
When the 100GBASE-SR4 QSFP28 fiber optical module transmits signals at the transmitting end, the electrical signals are converted into optical signals by the laser array, and then transmitted in parallel on the ribbon multimode fiber. When reaching the receiving end, the photodetector array converts the parallel optical signals Into parallel electrical signals.
The main features are as follows;
● 4 independent full-duplex channels
● Up to 28Gb/s data rate per channel
● QSFP28 MSA compliant
● Compliant to IEEE 802.3bm 100GBASE-SR4
● Up to 100m OM4 MMF transmission
● Operating case temperature: 0 to 70℃
● Single 3.3V power supply
● Maximum power consumption 3.5W
● MTP/MPO optical connector
● RoHS-6 compliant
3.100GBASE-CWDM4 QSFP28 Fiber Optical Module
The QSFP28 CWDM4 fiber optical module has a transmission rate of 103.1Gbp and is mainly used in computing, high-frequency trading and other fields. Its cost is significantly higher than that of the QSFP28 PSM4 fiber optical module.
Through coarse wavelength division multiplexing (CWDM) technology, the QSFP28 CWDM4 fiber optical module multiplexes four wavelengths of 1270nm, 1290nm, 1310nm and 1330nm onto a single-mode optical fiber for transmission.
The main features are as follows;
● QSFP28 MSA compliant
● 4 CWDM lanes MUX/DEMUX design
● Supports 103.1Gb/s aggregate bit rate
● 100G CWDM4 MSA Technical Spec Rev1.1
● Up to 2km transmission on single mode fiber (SMF) with FEC
● Operating case temperature: 0 to 70℃
● 4x25G electrical interface (OIF CEI-28G-VSR)
● Maximum power consumption 3.5W
● LC duplex connector
● RoHS compliant
