Juniper 10GBASE-LR SFP+ Transceiver Module, 1310 nm Single-Mode

A 10 km single-mode link at 10GbE is what the Juniper 10GBASE-LR SFP+ Transceiver Module, part number EX-SFP-10GE-LR, provides. It operates at 1310 nm with a duplex LC connector, in the SFP+ form factor.

A distribution or core uplink between buildings is a common case for the LR class, since single-mode fiber is the usual choice between buildings.

Planning checks are simple but worth doing. Confirm that the fiber is single-mode along the entire path, and measure the loss, including splices and patch panels, against the module's budget. Make sure the far end has a compatible LR module.

Switches look up the part number in a list of supported optics, so make sure your platform accepts this number. Behavior in other vendors' switches is not described, so check the host documentation if you plan to use it outside Juniper gear.

For links under a few hundred meters on multimode, the short-reach module is the cheaper choice. Choose LR when the distance or fiber type requires it.

The EX-SFP-10GE-LR is available in new, refurbished and used condition. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity and platform for pricing.
