The brocade cnas support active twinax from brocade or emc s active twinax cable.
Active optical cable vs twinax.
Seen from the material of the cable dac cable can be classified into direct attach copper cable and active optical cable aoc.
Twinax cable is a type of cable similar to coaxial cable.
This kind of cable is commonly used for very short range high speed differential signaling applications.
As of right now the qlogic 815x and emulex oce1012 support either active or passive twinax from both cisco and qlogic.
Currently there is a copper 10 gigabit ethernet cables which comes in either continue reading active and passive twinax sfp cable.
The dac cable is a fixed assembly that is purchased at a given length.
Twinax cable see in following figure is a type of cable similar to coaxial cable that has two inner conductors instead of one.
And owing to its cost efficiency it is commonly used in short range high speed differential signaling applications.
Cisco offers active optical cables in lengths of 1 2 3 5 7 and 10 meters.
10g twinax vs fiber.
Generally twinax cables shorter than 7 meters are passive and those longer than 7 meters are active but this may vary from vendor to vendor.
Cisco currently offers active optical cables in lengths of 1 2 3 5 7 10 15 20 25 and 30 meters.
Sfp h10gb acu10m vs sfp 10g aoc10m i ve been searching around but can t seem to find any reasons to use one over the other aside from cost about a 40 difference which leaves it at like half the cost of just one sfp module.
Why use active optical cable aoc cable.
The active one helps to improve signal quality and provides a longer cable distance.
The direct attach optical cables are cheaper than twinax but appear to have the same compatibility matrix.
You must know that twinax cable has two different types active twinax and passive twinax whose classification normally depends on twinax cable length.
Active optical cables are much thinner and lighter than copper cables which makes cabling easier.
Cisco sfp active optical cables figure 5 are direct attach fiber assemblies with sfp connectors.
Active optical cables enable efficient system airflow and have no emi issues which is critical in high density racks.
Primarily active optical cable aoc assemblies were invented to replace copper technology in data centers and high performance computing hpc applications.
They are suitable for very short distances and offer a cost effective way to connect within racks and across adjacent racks.
As we know copper passive twinax cable is heavy and bulky making it difficult to physically manage the datacenter.
Cisco sfp active optical cables.
Sfp sr is flexible and future proofing.
Currently there is a twinax cable which comes in either passive or active copper cable.
This partly explains why active sfp cable is usually more expensive than its passive counterparts.
For 10g twinax vs fiber we cannot make our decisions until we clear knows each function.
