Metro network segments needing cost‑efficient 10 Gb optical modules.
-
Upgrading legacy 1 Gb links to 10 Gb with minimal overhaul.
FAQ
Q: Will this transceiver work in non‑Juniper equipment?
A: It may work if the equipment supports the SFP+ LR spec and the part is accepted, but compatibility is verified for Juniper platforms. Juniper Networks
Q: What cable type is required?
A: Single‑mode fiber (9/125 µm) with LC duplex connectors.
Q: What’s the maximum distance?
A: Up to ~10 km over suitable SMF.
Q: Does it support lower speeds like 1 Gb or 5 Gb?
A: Primary specification is 10 Gb; some modules may negotiate lower depending on platform, but guaranteed for 10 Gb.
