H3C 10GBASE-ER XENPAK Module - 1 x 10GBase-ER - XENPAK

Product Description

The H3C XENPAK-LH40-SM1550 is a high-performance optical transceiver module designed to enable 10 Gigabit Ethernet connectivity over long distances using single-mode fiber optic cables. The 'XENPAK' designation refers to an older, larger form factor for 10GbE transceivers, often found in enterprise networking equipment from that era. This module specifically adheres to the 10GBASE-ER standard, which is optimized for extended reach applications. The 'LH' (Long Haul) and 'ER' (Extended Reach) specifications indicate that this module is capable of transmitting data over significantly longer distances than standard short-reach (SR) or intermediate-reach (LR) modules. It operates at a wavelength of 1550nm, which is characteristic of longer-distance fiber optic transmissions. This makes it suitable for connecting network devices across large campuses, between buildings, or in metropolitan area networks (MANs) where the distance exceeds the capabilities of typical LR modules. With a single 10GBase-ER port, the XENPAK-LH40-SM1550 provides a direct interface for connecting a 10GbE network device, such as a switch or router, to the fiber optic infrastructure. Its compatibility is typically with network equipment that supports the XENPAK form factor. This module is a critical component for extending high-speed network reach in environments where fiber optic cabling is deployed for backbone connectivity.
