A Quickie Observation of CVR-QSFP-SFP 10G

With the vast utilization of the 40 Gigabit network, it is significant to connect the current 10 Gigabit network to the 40 Gigabit network. At present, various adjustable solutions can support understanding 40 Gigabit-10 Gigabit migration: 40 Gigabit QSFP to 4x10 Gigabit SFP+ DAC breakout cables, 40 Gigabit QSFP to 4x10 Gigabit SFP+ AOC breakout cables; moreover CVR-QSFP-SFP 10 Gigabit modules. Amongst them, CVR-QSFP-SFP 10 Gigabit module can utilize the existing 10 Gigabit cabling for a 40 Gigabit-10 Gigabit transition.

How Can We Define a CVR-QSFP-SFP10G Module?

The CVR-QSFP-SFP 10 Gigabit optical module, which we can also name as 40G-10G-adapter or QSFP to SFP+ adapter, is a kind of the QSA adapter. We create it in a QSFP form factor with an enclosure for the SFP+ optical module behind. In other words, we can plug a low-speed SFP+ optical transceiver behind it, enabling single channel SFP+ optical transceivers to attach to four-channel QSFP ports. The 40G-10G-adapter works as an interface for the SFP+ optical transceiver during the procedure. This adapter allows the 40 Gigabit-10 Gigabit migration when the other end of the network functions at lower speeds.
CVR-QSFP-SFP 10 Gigabit features with low crosstalk, less insertion loss, easy installation, safe latching mechanism, network bring-up, and QSFP+ MSA compliant. It also possesses wide implementations in routers and switches, network storage systems, data servers, Infini-Band, and data center networking.

CVR-QSFP-SFP 10G: Genuine QSA Solution for 40 Gigabit-10 Gigabit Migration:

As the 40G-10G-adapter provides trouble-free connectivity between 40 Gigabit and 10 Gigabit devices by utilizing SFP+ based cabling, we consider it a reasonable solution for changing 40 Gigabit ports to the 10 Gigabit ports after introduction.
40G-10G-adapter supports each SFP+ cable and is adaptable to mainstream SFP+ modules and switch models. Below is a list of SFP+ optical transceiver modules that we can plug.

Here is a standard 40 Gigabit-10 Gigabit implementation case: with the support of two 10GBASE-SR SFP+ optical transceiver modules, a duplex LC multimode fiber optic patch, and one QSFP to SFP+ adapter, we can smoothly realize 40 Gigabit to 10 Gigabit migration.

A Comparison between 40 Gigabit QSFP Breakout Cables and CVR-QSFP-SFP 10 Gigabit Adapter:

An Analysis of 40 Gigabit QSFP to 4x10 Gigabit SFP+ Breakout Cables:

CVR-QSFP-SFP 10 Gigabit breakout cable contains four SFP+ connectors and a QSFP connector on the other ending. We can generally divide CVR-QSFP-SFP 10 Gigabit breakout cable into DAC and AOC cable. We use them to transfer 40 Gigabytes per second data into four different streams of 10 Gigabytes per second data above a fan-out wire in a multipoint configuration.

Differences between QSFP+ Breakout Cables and CVR-QSFP-SFP 10G Adapter:

As we have mentioned earlier, we can utilize a CVR-QSFP-SFP 10 Gigabit adapter to change a QSFP port to a small form factor pluggable+ port. Or we are taking on QSFP to 4x10 Gigabit small form factor pluggable+ breakout cables to break a 40 Gigabit port between a server or a switch into four 10 Gigabit ports. In short, both QSFP+ breakout cables and QSFP to SFP+ adapter are presenting adaptable solutions for the 40G-10G conversion. However, what is the difference between them? We will analyze the differences between the two solutions from three viewpoints: performance, price, and deployment.

Performance:

QSFP+ to 4x10 Gigabit small form factor pluggable+ breakout cables break the 40 Gigabit channel into 4x10 Gigabit channel, which offers more data transmission compared to QSFP to SFP+ adapter that provides connectivity for a single 10 Gigabit link only.

Price:

It is easy to observe that the price of a product partly has a connection to its commerciality in the market. CVR-QSFP-SFP 10 Gigabit can be more costly than we expect on the market because of a particular patent by a few sellers. Direct-attach copper breakout cables offer the most low-priced solution for limited-reach transmission.

Deployment:

Every solution has its appropriate point about the application in multiple scenarios. When a single 10 Gigabit device requires to attach the switch, utilizing a CVR-QSFP-SFP 10 Gigabit is more convenient. On the other hand, there are different 10 Gigabit devices in separate places that require connecting to 40 Gigabit switches. In this situation, the adopter also provides a low-price solution. Nevertheless, if the marketing of these 10 Gigabit devices is complicated, QSFP+ breakout cables are suitable for an ideal ROI.

Conclusion:

Even though CVR-QSFP-SFP 10 Gigabit optical modules can present a single 10 Gigabit connection and be more expensive for the particular patent by a few sellers, they are the ideal solution for changing 40 Gigabit ports to the 10 Gigabit ports after introduction. With QSFP to SFP+ adapter, which is supportive for all SFP+ cables and is adaptable to mainstream SFP+ modules and switch models, we can realize the trouble-free connectivity between devices that utilize 40 Gigabit QSFP+ port and 10 Gigabit SFP+ ports.
