Detailed Specifications
HPE JG234A 10 Gigabit SFP+ LC ER 40 km SMF Optical Transceiver Module
Overview
The HPE JG234A is a 10 Gigabit Ethernet SFP+ optical transceiver engineered for single-mode fibre (SMF) links. It uses an LC duplex connector, operates at a wavelength of approximately 1550 nm, and is rated for link distances up to about 40 km under standard SMF conditions. This makes it well suited for long fibre uplinks between buildings, wiring closets, aggregation switches or campus backbone segments. Since it plugs into standard SFP+ cages in HPE network switches and routers, it lets you extend 10 Gb connectivity without replacing the host device.
In practical deployment you might use this module to connect two campus buildings, or link a data-centre access switch to aggregation over single-mode fibre where copper or multimode fibre is unsuitable.
Key Features
10 Gbps throughput in SFP+ form-factor supports high-bandwidth backbone or uplink links.
Single-mode fibre support via LC duplex connector and 1550 nm wavelength enables long-reach (~40 km) links between sites.
Compatible with HPE networking equipment (X130 series and others) designed for SFP+ ER optics.
Hot-swappable module with industry standard SFP+ footprint; supports diagnostics (DDM) in compatible platforms for monitoring optical performance.
