EX-SFP-10GE-ER — 10GBase-ER 40Km Optics Module

The EX-SFP-10GE-ER is a Juniper 10GBase-ER SFP+ module for links up to 40 km over single-mode fiber via a Duplex LC connector. With a 40 km reach, it sits between the LR (10 km) and the ZR (80 km) in the Juniper EX range, covering medium-reach metropolitan link requirements without the need for optical amplifiers. Its 0 to 70 degrees C operating range ensures reliable operation in standard datacenter and equipment room environments.

This transceiver is suited to multi-site enterprises and operators interconnecting points of presence or collection nodes tens of kilometers apart. Its 40 km reach gives it an advantage over the LR for regional links without requiring the higher transmit power of a ZR. Genuine Juniper hardware, manufacturer warranty.
