About This Part
The HP JG991A is a high-performance SFP+ (Small Form-Factor Pluggable Plus) Dense Wavelength Division Multiplexing (DWDM) optical transceiver module. Engineered for enterprise and carrier-grade networking environments, this module facilitates robust 10 Gigabit Ethernet connectivity over extended distances. Operating at a precise wavelength of 1537.40nm, corresponding to DWDM Channel 50, the Part Number JG991A is specifically designed for integration into DWDM systems, enabling multiple data streams to be transmitted simultaneously over a single optical fiber. Its SFP+ form factor ensures compatibility with a wide range of network equipment, supporting a data rate of 10 Gbps and an impressive reach of up to 80 kilometers over single-mode fiber (SMF). This makes it an ideal solution for inter-data center links, metropolitan area networks (MANs), and long-haul enterprise connections where high bandwidth and extended reach are critical. The module adheres to industry standards for optical transceivers, ensuring reliable and interoperable performance within complex network infrastructures. The HP JG991A transceiver is typically deployed in core network infrastructure, including high-density Ethernet switches, routers, and optical transport platforms that support SFP+ interfaces. Its primary application lies in scenarios demanding high-bandwidth, long-distance optical links, such as connecting geographically dispersed data centers, extending metropolitan area networks, or building robust backbone infrastructure for internet service providers (ISPs) and telecom operators. By leveraging DWDM technology, this module allows network architects to maximize the capacity of existing fiber optic cables, effectively multiplying the available bandwidth without the prohibitive cost and complexity of deploying new fiber. It is instrumental in upgrading legacy 1G or 2.5G networks to 10G speeds, providing a scalable and efficient solution for handling increasing data traffic volumes. Industries benefiting from this technology include telecommunications, cloud service providers, large enterprises with campus networks, and financial institutions requiring low-latency, high-throughput connections over significant distances.
