EX-SFP-10GE-LR Juniper Module

EX-SFP-10GE-LR is an optic, not a network switch

Juniper lists this exact order as a 10-Gigabit Ethernet SFP+ transceiver using 10GBASE-LR. The published optical profile is 1310 nm with a 10 km single-mode fiber reach. It is a pluggable link component; the switch, router, line card and fiber path are separate parts of the installation.

Distinguish LR from other EX optical orders

The same official ordering table separates the LR single-mode design from EX-SFP-10GE-SR, an 850 nm multimode order, and EX-SFP-10GE-ER, a 1550 nm longer-reach order. Select against the installed fiber path and remote interface instead of choosing on the SFP+ form factor alone.

Verify the host and software together

Juniper Hardware Compatibility Tool associates this optic with part number 740-021309. Its ACX7509 entry identifies ACX7509-FPC-20Y and an introduced release of Junos OS Evolved 21.4R1. This is one documented host relationship, not a promise of compatibility with every EX, QFX, MX or third-party port. Check the target chassis, line card, port mode and software release in the current tool.

Keep acceptance tied to the offered module

Compare the model and part-number labels with the quotation, then check the actual optical link budget and both link endpoints before installation. A published maximum reach does not establish the condition of a used optic or guarantee a particular fiber route. Confirm the offered quantity, condition and accessories separately.
