What’s The Advantage of 100G QSFP 28 Optical Module Compared with 100G CFP4 Optical Module?
Latest company news about What’s The Advantage of 100G QSFP 28 Optical Module Compared with 100G CFP4 Optical Module?

As 5G (the fifth generation of cellular mobile communications) technology is explosive developing,100G is becoming more and more familiar, but we really know 100G Optical Module? Compare with 100G CFP4 Optical module, what’s the price advantage and disadvantage of 100G QSFP28 Optical module?Facing the dazzling product and price, how to find the best one? Now let GLGNET analyze in detail.

 

1. What’s QSFP28 Optical Module? What’s CFP4 Optical Module?

 

5G means fifth generation of cellular mobile communications. 100G means the optical module data rate. We review the 100G optical module development history, people do much work to develop and improve the package and standard of optical module, the ultimate purpose is to reduce cost the consumption.

 

2. Performance comparison between 100G QSFP28 optical module and 100G CFP4 optical module

 

(1)Port Density

 

CFP4 Optical module is the newest 100G optical module.Compared with QSFP28 optical module, although the CFP4 optical module width is only 1/4 of the first generation CFP optical module, the package is still bigger that QSFP28 optical module, that means the QSFP28 optical module port utilization is better than CFP4 optical module.

(2)High density cable wiring

 

For 100g QSFP28 optical module, there are 4 fiber channels for transmitting data, and per channel data rate can reach 28Gbps Max, mainly used for 100G transmission application, compared with 100G CFP4 optical module, 100G QSFP28 optical module is more practicable for high density cable wiring, more data center prefer to choose 100G QSFP28 optical module.

 

(3)Optical Module Category

 

For 100G optical module and 100GCFP4 optical module, they both have many subtypes, as below list:

 

100G CFP4 optical module Interface Optical fiber type Transmission distance
100G CFP4 SR4 LC Duplex Multiple mode 100m(OM3)
100G CFP4 LR4 LC Duplex Multiple mode 10km
100G CFP4 ER4 LC Duplex Multiple mode 40km

 

100G QSFP28 Optical module Interface Optical fiber type Transmission distance
100G QSFP28 SR4 MTP Multiple mode 70m(OM3),100m(OM4)
100G QSFP28 LR4 LC Duplex Single mode 10km
100G QSFP28 ER4 LC Duplex Single mode 40km
100G QSFP28 PSM4 MTP Single mode 500km
100G QSFP28 CWDM4 LC Duplex Single mode 2km

 

We can see from the data sheet,, there are more 100G QSFP28 optical module types than 100G CFP4 optical module types, that means 100G QSFP28 optical module is more widely used, and 100G QSFP28 optical module also have longer transmission distance, the developing is faster.

 

3、Price comparison between 100G QFSP28 optical module and 100G CF4 optical module

 

 

Product Specification Price
100G CFP4 SR4 Package: CFP4; Wave length:850nm; Interface: LC Duplex; Cable: Multiple mode MMF; Speed: 103.1Gbps;MAX Transmission distance:100m $545/Set
100G QSFP28 SR4 Package: QSFP28; Wave length:850nm; Interface: MTP/MPO-12; Cable: Multiple mode MMF; Speed: 103.1Gbps;MAX Transmission distance:100m $218/Set
100G CFP4 LR4 Package: CFP4; Wave length:1310nm; Interface: LC Duplex; Cable: Single mode SMF; Speed: 112Gbps;MAX Transmission distance:10km $3500/Set
100G QSFP28 LR4 Package: CFP4; Wave length:1310nm; Interface: LC Duplex; Cable: Single mode SMF; Speed: 103.1Gbps;MAX Transmission distance:10km $1635/Set
100G CFP4 ER4 Package: CFP4; Wave length:1310nm; Interface: LC Duplex; Cable: Single mode SMF; Speed: 112Gbps;MAX Transmission distance:40km $10565/Set
100G QSFP28 ER4 Package: CFP4; Wave length:1310nm; Interface: LC Duplex; Cable: Single mode SMF; Speed: 103.1Gbps;MAX Transmission distance:40km $7635/Set

Note:Price is volatile according to market.

 

 

We can see 100G QSFP28 optical module has better price and faster developing, that will also save much time and cost when next updating.
