The copper RJ-45 transceiver can be used for short distances with network cables, with lower power consumption. In the data center of copper cabling, copper RJ-45 transceivers are more widely used and lower in cost. The optical transceiver should be selected when the transmission distance is relatively long.

There are some differences between AOC active optical cables and DAC high-speed cables

TEOSCO released 200G QSFP56 SR4, DR4 and FR4 optical transceivers. 200G QSFP56 uses mainstream Digital Signal Processor (DSP) and hot-swappable QSFP56 package. It has 4 independent channels for transmission and reception, the rate of each channel is 53G.

Compared with ordinary optical transceivers, the biggest difference is xWDM optical transceiver can save fiber resources and costs. At present, the commonly used 25G WDM optical transceivers are divided into 25G CWDM, 25G DWDM and 25G LWDM optical transceivers.

The more commonly used optical transceiver are generally LC interface or MPO interface. Optical modules with different interfaces should be connected with the corresponding interface jumper. LC interface has its presence in optical transceiver of all speeds, while MPO interface usually exists in high-speed optical transceiver.

TEOSCO has released 25G SFP28 series, it includes SFP28 SR, LR, ER Lite, BIDI SFP28, CWDM SFP28, SFP28 AOC cables and SFP28 DAC cables.
