Juniper SFP-GE40KT13R14 1GE BIDI 40 km SFP | Enterprise Optics

Move 1 GbE traffic farther without changing the shape of the deployment. This bidirectional SFP transceiver is designed for 40 km links, making it a practical choice for long-reach Ethernet where standard short-distance optics fall short. The T13/R14 pairing supports bidirectional transmission over a single fiber pair, helping reduce cabling complexity while keeping the optics layer compact. For Juniper-based networks, this module fits the operational model of hot-swappable SFP optics and gives infrastructure teams a clean way to extend connectivity between buildings, across campus backbones, or into metro aggregation paths. It is the kind of transceiver you specify when the link budget matters and the cost of overbuilding the optical layer does not. Compared with shorter-reach modules, this optic earns its place by covering distance without moving to a larger or more complex platform. That makes it useful for teams that need predictable 1 Gigabit transport over long spans and want to preserve port density, simplify fiber plant design, and keep the network aligned to the actual reach requirement.
