In general, there are three ways of 25G access of server, namely DAC (Direct Attach Cable), optical transceiver and AOC(Active Optical Cable).
DAC can reach no more than 5m, so it is difficult to meet the requirements of cross-rack wiring distance.
The optical transceiver can reach up to 100m or more using multi-mode fiber, but the cost is high.
AOC is an Active Optical Cable. AOC can reach up to 30m at a reasonable cost.
Therefore, AOC cable is a good choice for cross-rack server access, which is more suitable for China's current data center rack power and network architecture. Here’s some information about the 25G AOC that you may be wondering about.
25G AOC provides a cost-effective solution for those same data center applications that require longer distance interconnect using active optical Ethernet technology. There are some advantages to 25G AOC.
25G provides 2.5 times the bandwidth of 10G using in the same SFP form factor
25G is ideal for data center top of the rack, wireless backhaul and enterprise interconnect applications
25G meets the newest server adapter requirements
10/25G transceivers are compatible with 10G, 25G, 40G and 100G transceivers
The Gigalight 25G SFP28 Active Optical Cables (AOCs) are direct-attach fiber assemblies with SFP28 connectors, compliant with 25G Ethernet IEEE 802.3by 25GBASE-SR standard. They are suitable for short distances and offer a cost-effective solution to connect within racks and across adjacent racks. The length is up to 70 meters using OM3 MMF and 100 meters using OM4 MMF. COB solution is used in the TX and RX.
The pre-FEC bit error ratio (BER) is guaranteed to meet E10-8 25.78125Gb/s@PRBS31, 55℃, Better than the IEEE pre-FEC BER of less than 5 E-5.

Active optical cables play a key role in the data center market. Active optical cables are largely used in the data center to meet the need for increased bandwidth and low power. The data center market also needs a broad portfolio of fiber optic modules to connect servers, switches, and storage, which is accomplished by an active optical cable. Therefore, the increase in the deployment of data centers is a key factor behind the growth of the active optical cable market.
