What differences does fiber optical 100G QSFP28 brings ?

Fiber optical sfp 100G networks will be the most popular type in the next 10 years even now 10G networks is still the most popular one. But a lot of network builders are choosing 100G to replace it. But how to replace it and which is the most economic way? They need think about this.

As we all know, Cloud Optical Transceivers QSFP28 100G products is very expensive. Considering the cost, a lot of network builders choose 10G→40G→100G before QSFP28 come out. At that time there are 100G products such CFP, CFP2 and CFP4 (“C” for 100, and FP for “Form factor, Pluggable”). But the form fact of all these are huge even the newest CFP4 is still bigger than QSFP28. Please refer to the picture below:

After 100GBASE QSFP28 has been released, it provides a more economic way. We can choose 10G→25G→100G, because 100G Ethernet is formed by 4*25Gbps. QSFP28 form factor make it possible to install more transceivers in one 1RU switch.

With respect to 40GE, 25GE enjoys the cost advantages of single channel. If it is 40G, multiple physical channels are required, because it makes use of 10G technology. For 25G Ethernet, the key advantage is that many components have been completed: because 100G Ethernet is formed by 4 25Gbps. Therefore, the components generated using the two kinds of technology can be produced in mass, to drive down the price.

Besides, the consumption of QSFP28 is below 3.5W which is much lower than other 100G products (6~24W). The GEN2 100G QSFP28 released by Infiberone only cost 2.5W.

Infiberone Starts Batch Production of 40G QSFP GEN2 Optical SFP Transceivers

40g-qsfp-infiberone

Infiberone announced last Friday it’s gone into the batch production of their newly released 40G QSFP GEN2 optical transceiver. The main difference between 40G QSFP GEN2 and existing 40G QSFP on the market lies in the multichannel real-time DDM function, which is easy to realize for transceivers with data rate lower than 10Gbps, but very complicated for those more than 10Gbps, as the latter is mostly based on COB not TO packaging technique. As for parallel high-speed optical transceiver with higher rate, it requires excellent design and precise layout to realize optic circuit detection on 4-channel or 12-channel array light chip in an extremely limited space, which has been met by Infiberone patented optical engine technology. Starting optical engine technology development since 2011, now by its own endeavor and cooperation with quality suppliers, Infiberone has gained rich experience and unique technology about array LENS development and integrated optical devices coupling capsulation. It is a critical mission for Infiberone R&D long-term works that realizing multichannel optical power DDM real-time monitoring of high-speed parallel optical module. Lack of optical power real-time monitoring does not influence optical modules regular operation; however Infiberone‘s been striving to create product higher than industry standard and holds firm pursuit of optical module complete functions, and finally they reach this goal.

It says that Infiberone new launched GEN2 optical module will not largely increase clients’ purchasing cost. The bulk price of GEN1 and GEN2 almost reach equilibrium, even GEN2 module is a truly flawless product compliant with related standards. Infiberone launched this new product at CIOE in September 2015, and now plans to completely switch the generation products in the first half of 2016.

By the way, Infiberone is going to attend OFC exhibition in USA this month, let’s meet there to communicate about new products.
