Active Optical Cable Vs Twinax

Cisco currently offers active optical cables in lengths of 1 2 3 5 7 10 15 20 25 and 30 meters.

Active optical cable vs twinax.

As of right now the qlogic 815x and emulex oce1012 support either active or passive twinax from both cisco and qlogic. The difference is that there are two inner conductors other than on in coaxial cable. Twinax cable see in following figure is a type of cable similar to coaxial cable that has two inner conductors instead of one. You must know that twinax cable has two different types active twinax and passive twinax whose classification normally depends on twinax cable length.

As we know copper passive twinax cable is heavy and bulky making it difficult to physically manage the datacenter. They are suitable for very short distances and offer a cost effective way to connect within racks and across adjacent racks. The active one helps to improve signal quality and provides a longer cable distance. Currently there is a twinax cable which comes in either passive or active copper cable.

For 10g twinax vs fiber we cannot make our decisions until we clear knows each function. The dac cable is a fixed assembly that is purchased at a given length. Cisco sfp active optical cables. 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.

10g twinax vs fiber. The direct attach optical cables are cheaper than twinax but appear to have the same compatibility matrix. Why use active optical cable aoc cable. Active optical cables are much thinner and lighter than copper cables which makes cabling easier.

Currently there is a copper 10 gigabit ethernet cables which comes in either continue reading active and passive twinax sfp cable. Twinax cable is a type of cable similar to coaxial cable. Cisco sfp active optical cables figure 5 are direct attach fiber assemblies with sfp connectors. Sfp sr is flexible and future proofing.

The circuitry in active sfp cable thus brings up the overall cost. Active optical cables enable efficient system airflow and have no emi issues which is critical in high density racks. If you want to connect a brocade cna to a cisco tor switch nexus you could use the emc active twinax cable. The brocade cnas support active twinax from brocade or emc s active twinax cable.

This partly explains why active sfp cable is usually more expensive than its passive counterparts. This kind of cable is commonly used for very short range high speed differential signaling applications. Primarily active optical cable aoc assemblies were invented to replace copper technology in data centers and high performance computing hpc applications. Cisco offers active optical cables in lengths of 1 2 3 5 7 and 10 meters.
