Active Optical Cable Vs Twinax

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.

Active optical cable vs twinax.

Sfp sr is flexible and future proofing. Currently there is a copper 10 gigabit ethernet cables which comes in either continue reading active and passive twinax sfp cable. As we know copper passive twinax cable is heavy and bulky making it difficult to physically manage the datacenter. Primarily active optical cable aoc assemblies were invented to replace copper technology in data centers and high performance computing hpc applications.

The brocade cnas support active twinax from brocade or emc s active twinax cable. You must know that twinax cable has two different types active twinax and passive twinax whose classification normally depends on twinax cable length. This partly explains why active sfp cable is usually more expensive than its passive counterparts. They are suitable for very short distances and offer a cost effective way to connect within racks and across adjacent racks.

The circuitry in active sfp cable thus brings up the overall cost. Cisco sfp active optical cables figure 5 are direct attach fiber assemblies with sfp connectors. Twinax cable see in following figure is a type of cable similar to coaxial cable that has two inner conductors instead of one. Currently there is a twinax cable which comes in either passive or active copper cable.

10g twinax vs fiber. The direct attach optical cables are cheaper than twinax but appear to have the same compatibility matrix. The active one helps to improve signal quality and provides a longer cable distance. Active optical cables enable efficient system airflow and have no emi issues which is critical in high density racks.

Cisco offers active optical cables in lengths of 1 2 3 5 7 and 10 meters. As of right now the qlogic 815x and emulex oce1012 support either active or passive twinax from both cisco and qlogic. For 10g twinax vs fiber we cannot make our decisions until we clear knows each function. This kind of cable is commonly used for very short range high speed differential signaling applications.

If you want to connect a brocade cna to a cisco tor switch nexus you could use the emc active twinax cable. Cisco currently offers active optical cables in lengths of 1 2 3 5 7 10 15 20 25 and 30 meters. Seen from the material of the cable dac cable can be classified into direct attach copper cable and active optical cable aoc. Cisco sfp active optical cables.

The difference is that there are two inner conductors other than on in coaxial cable. Active optical cables are much thinner and lighter than copper cables which makes cabling easier. Why use active optical cable aoc cable. The dac cable is a fixed assembly that is purchased at a given length.
