Juniper EX-SFP-10GE-SR 10GBASE-SR SFP+ Optical Transceiver

850nm short-reach optic for graded multimode cabling

Juniper EX-SFP-10GE-SR, part number 740-021308, is a 10GBASE-SR SFP+ transceiver. Its exact Juniper record identifies an 850nm optical interface, duplex LC PC/UPC connector, digital optical monitoring and maximum power consumption of 1W.

Reach depends on the MMF grade

Juniper does not give one universal distance for every multimode plant. The record lists 300m on OM3 and 400m on OM4, with shorter limits for earlier fiber grades. Confirm the cable grade throughout the complete route, including trunks and patch leads, before using a distance target.

SR is a distinct optical path

This SKU is for multimode fiber and 850nm operation. It must not be treated as the 1310nm LRM model or as a single-mode LR optic. The far-end module, wavelength, optical standard, polarity and fiber grade must form one compatible link design.

Qualification before installation

Check the exact host platform, interface module and Junos release in the Juniper Hardware Compatibility Tool. A physically compatible SFP+ slot alone does not prove that EX-SFP-10GE-SR is supported by the deployed hardware and software combination.

Commissioning record

At receiving, match both EX-SFP-10GE-SR and 740-021308. Inspect and clean the LC interfaces, then record DOM transmit power, receive power and alarms after the link is stable. Fiber jumpers and the remote-end optic are separate from this one-transceiver SKU.
