Juniper SRX-SFP-1GE-LH 1000Base-LH SFP | Gigabit Ethernet, Single-mode

Extend Gigabit Ethernet connectivity across longer fiber runs with the Juniper SRX-SFP-1GE-LH optical module. Built for 1000Base-LH operation, this SFP delivers 1 Gbps transport over single-mode fiber in a compact mini-GBIC form factor. It is a practical fit for branch and edge environments where copper reach is not enough and optical uplinks need to stay simple, predictable, and compatible with Juniper infrastructure. This module is designed for data networking use and is listed for the SRX210 base system, making it a targeted choice for teams standardizing on Juniper security and routing platforms. The single-port design keeps deployment straightforward, while the long-haul optical profile supports cleaner uplink planning across wiring closets, remote rooms, and distributed sites. Compared with generic transceivers, this Juniper module is specified for the platform it serves, which helps reduce compatibility risk and avoids the guesswork that can slow down maintenance windows. For organizations that value stable optics, consistent performance, and vendor-aligned support, the SRX-SFP-1GE-LH is the right class of component for extending critical network paths without overbuying capacity.
