Juniper EX-SFP-GE40KT13R15 SFP 1000-BX GE 40 km | LC, Single-mode

Build long-reach fiber links with a 1 GbE bidirectional SFP engineered for asymmetric TX 1310 nm and RX 1550 nm operation. This optical profile is used when teams need to preserve distance without moving to a more complex transport design. The LC interface and single-mode support make it a practical fit for structured fiber environments where port density, reach, and predictable optics all matter. At 40 km, this module is suited to campus interconnects, metro aggregation, and remote facility links that need more than short-reach optics can provide. It is the kind of transceiver that earns its place in production by reducing link uncertainty and keeping the optical path aligned with the network design. For Juniper environments, this SFP is a focused replacement or expansion part that supports disciplined infrastructure planning. It is not about adding features for their own sake; it is about preserving signal integrity, reach, and operational consistency where the cost of a weak link is high.
