Juniper JNP-QSFP-40G-LX4 40Gb/s QSFP+ 2km Duplex LC SMF Transceiver

Product Description

The Juniper JNP-QSFP-40G-LX4 is a high-performance optical transceiver module designed to enable 40 Gigabit Ethernet connectivity over extended distances. It adheres to the QSFP+ (Quad Small Form-Factor Pluggable Plus) standard, which is widely adopted for high-density, high-speed networking applications. This specific module is engineered for the 40GBASE-LX4 standard, which utilizes wavelength division multiplexing (WDM) to transmit four separate 10Gbps optical signals over a single pair of single-mode fibers. This approach allows for efficient use of fiber infrastructure while achieving the aggregate 40Gbps data rate. The module operates using four parallel 1310nm optical lanes. The 'LX4' designation signifies its capability to transmit over longer distances compared to SR (Short Reach) transceivers, reaching up to 2 kilometers on standard single-mode fiber optic cabling. The use of single-mode fiber is crucial for maintaining signal integrity over these extended lengths, making it suitable for interconnecting switches, routers, and servers within large data centers, between buildings on a campus, or in other metropolitan area network (MAN) deployments. Connectivity is established via a duplex LC fiber optic connector, a common and robust interface for fiber optic communications. The JNP-QSFP-40G-LX4 is designed to be hot-swappable, allowing for installation or replacement without the need to power down the host equipment, thereby minimizing network downtime. It is typically used in Juniper Networks switches and routers that support QSFP+ interfaces, providing a reliable and high-bandwidth solution for network aggregation and backbone connectivity.
