Product Review

The Juniper PB-8GE-TYPE2-SFP-IQ2 offers a satisfactory balance between performance and scalability, supporting 2:1 oversubscription and requiring SFP modules which allows for flexible network configurations. With a MTBF of 200,000 hours, it promises reliability, but the power requirement of 0.89 A at 48 V (42.5 W) for the 8-port configuration may be a consideration for energy-conscious deployments. However, its capability to support high-performance throughput of up to 4 Gbps per port and large MTUs up to 9192 bytes positions it as a viable option for environments demanding high data rates and extensive data transmission sizes.


The Juniper PB-8GE-TYPE2-SFP-IQ2 is a high-capacity network interface card designed to provide secure and high-speed Gigabit Ethernet connectivity for enterprise networks. This card is equipped with eight ports that support Gigabit Ethernet Type 2 IQ2 PIC, enabling efficient data handling and network management. It is engineered to meet the demands of high-performance networking, offering a maximum data transfer rate of 1 Gbit/s with the capability to handle large volumes of traffic with its support for up to 2:1 oversubscription. This requires the use of SFP modules to facilitate various network connection standards, including optical and copper links. The physical dimensions of the PB-8GE-TYPE2-SFP-IQ2 are compact, with a width of 4 inches, a height of 1 inch, and a depth of 7 inches, making it suitable for installation in various network environments without requiring excessive space. The device is designed for durability and long-term reliability, with a Mean Time Between Failures (MTBF) of 200,000 hours, ensuring consistent performance over its lifespan. In terms of connectivity, this card offers flexibility through its eight total expansion slots, all of which are SFP (mini-GBIC) slots. These slots allow for a wide range of network connections, including both optical and copper interfaces. The optical connections utilize LC/PC connectors, while copper connections are facilitated through RJ-45 connectors using four-pair, Category 5 shielded twisted-pair cables. The card's power requirements are modest, needing only 0.89 A at 48 V (42.5 W) for the 8-port Type 2 configuration, ensuring efficient power consumption. It boasts high-performance throughput on each port, with speeds up to 4 Gbps in full-duplex mode. This allows for the rapid transmission of data across the network, reducing bottlenecks and improving overall network efficiency.
  • Supports large maximum transmission units (MTUs) of up to 9192 bytes, facilitating the transfer of large data packets and improving network performance.
  • Features a 20 Gbps throughput, enhancing the card's ability to handle high volumes of network traffic seamlessly.
  • Includes 64 source MAC address filters and 960 destination MAC filters, providing advanced network security and traffic management capabilities.
The Juniper PB-8GE-TYPE2-SFP-IQ2 is compatible with 1000Base-T networks, indicated by the model number SFP-1GE-T, ensuring it can be seamlessly integrated into existing network infrastructures. This compatibility, combined with the card's advanced features and specifications, makes it an ideal choice for organizations looking to upgrade their network's performance, reliability, and security. In summary, the Juniper PB-8GE-TYPE2-SFP-IQ2 is a versatile and efficient network interface card that offers high-speed Gigabit Ethernet connectivity, a wide range of network connection options through SFP modules, and advanced network management features. Its compact size, high MTBF, and efficient power consumption make it a valuable addition to any enterprise network infrastructure, ensuring reliable and high-performance network connectivity.
