Description
The HP 300834-B21 is a Gigabit Interface Converter (GBIC) transceiver module that provides 1 Gigabit Ethernet connectivity over multi-mode fiber. It operates at a wavelength of 850nm, which is standard for short-wavelength transceivers used with multi-mode fiber optics. This module is designed to support data transmission distances of up to 550 meters, making it suitable for intra-building or campus network links. The GBIC form factor is an older standard compared to SFP or SFP+, but it was widely adopted in early Gigabit Ethernet implementations. This module features an SC connector, a common type of fiber optic connector known for its robust and secure connection. The hot-pluggable nature of the GBIC allows for easy installation and replacement without requiring a system reboot, which is essential for maintaining network availability. This transceiver is compatible with networking equipment that features GBIC slots, offering a reliable solution for extending network reach over existing multi-mode fiber infrastructure. It is an integral part of many legacy HP networking deployments, providing essential connectivity for servers, switches, and routers where 1Gb/s speeds are sufficient.
