ProLabs B1003491: 1000Base-SX SFP transceiver, 850nm laser.

The ProLabs B1003491 is a 1000Base-SX SFP transceiver using an 850nm laser for short-reach Gigabit Ethernet links over multimode fibre, typically reaching up to 550 metres depending on fibre grade. It fits any standard SFP cage on switches, routers and media converters that support Gigabit Ethernet optics, and is built by ProLabs as a cost-effective alternative to original-brand modules for this common link type. Genuine ProLabs transceivers of this kind remain a routine requirement for network maintenance and fibre link expansion. Specifiers should confirm host-platform compatibility with third-party SFPs before ordering. Tech-Star (UK-based, shipped worldwide) supplies the B1003491 for engineers maintaining these deployments.
