August 4, 2021 — Facing the explosive growth of Internet technology and data nowadays, data centers, communication network equipment vendors and network operators are increasingly eager for further improvement of broadband speed and transmission distance. At present, on the 40km long-distance transmission track, limited by technology and cost, users can only choose optical transceiver modules with speeds of 100G and below. If users need higher transmission speed of 40km long distance, the expensive coherent optical transceivers will be the sole option, while they have to bear the high cost. In order to fill the market gap and satisfy development needs, FIBERSTAMP recently launched a 200G optical transceiver applicable for 40km long-distance metro DCI – 200G QSFP56 ER4, which refreshes the transmission rate of optical transceivers in the 40km track, and well balance the cost simultaneously！
This product uses the mainstream 4-lane WDM optical engine architecture, which integrates 4-lane cooled EML TOSA, APD ROSA and 50G PAM4 CDR based on DSP technology, empowering it with superior comprehensive performance. At the same time, it complies with the QSFP MSA standard, supports IEEE 802.3cn 200GBASE-ER4 Ethernet and OTN protocols, and supports a maximum transmission distance of 40km, well applicable for 200G long-distance metro DCI and 5G backhaul.
This 200G QSFP56 ER4 optical transceiver also has excellent performance in terms of power consumption. According to actual test results, its power consumption is as low as 6.4W at normal temperature, and can keep less than 7.5W at testing temperatures of 0℃, 25℃ and 75℃, which can help users greatly save the energy costs.
In addition, this product has excellent OMA sensitivity, the actual test result is lower than -17dBm, entrusting it with an absolute advantage in long-distance transmission.
It is worth mentioning that based on the long-term and deep cultivation in the field of 200G high-speed optical interconnection, FIBERSTAMP has developed a complete, professional and economical 200G optical interconnection product line, which can provide users with full coverage and highly targeted optical transmission network solution!
