GIGALIGHT Launches 100G QSFP28 ER4&eER4&ZR4 Modules
Shenzhen, China, July 20, 2021 − GIGALIGHT today announced the launch of three 100G long-distance optical transceiver modules, OTU4 100G QSFP28 ER4&eER4&ZR4. These modules feature the industry’s leading performances, suitable for metropolitan area networks, 5G backhaul and data center interconnection (DCI).
- Dual Rates: both 100GE and OTU4 rates are supported in the full temperature range
- Ultra Long Reach: ER4 and eER4 up to 40km and 60km respectively without FEC (Zero BER); ZR4 up to 90km (5E-5 BER)
- Low Power Consumption: 4.4W at 25℃ and less than 6W at 70℃
