Description

The Juniper EX-SFP-10GE-USR is a high-performance 10 Gigabit Ethernet SFP+ optical transceiver designed to provide reliable short-distance fiber connectivity in enterprise and data-center networking environments.

Using 850 nm optical transmission over multimode fiber, the transceiver provides a practical solution for connecting compatible Juniper networking equipment over short fiber runs. It supports up to 100 meters on OM3 multimode fiber, with shorter supported distances on OM1 and OM2 fiber.

The EX-SFP-10GE-USR uses the compact SFP+ form factor, allowing it to be installed directly into compatible SFP+ interfaces on supported switches, routers, and other network equipment.

10 Gigabit Ethernet Performance

The EX-SFP-10GE-USR is designed for 10 Gigabit Ethernet networking, providing high-bandwidth connectivity for applications that require more performance than traditional Gigabit Ethernet.

It is suitable for:

• Switch-to-switch connections
• Server-to-switch connectivity

• Enterprise network uplinks
• High-speed storage connectivity
• Network infrastructure interconnections

850 nm Multimode Fiber Optics

The transceiver operates at an 850 nm wavelength and is designed for multimode fiber.

Juniper specifies the following maximum transmission distances:

These distances make the EX-SFP-10GE-USR particularly suitable for short-range connections within equipment racks, server rooms, and data centers.

SFP+ Form Factor

The compact SFP+ form factor makes the EX-SFP-10GE-USR suitable for high-density networking equipment.

SFP+ modules can be installed into compatible SFP+ ports without requiring a separate external media converter, helping network administrators maintain a clean and efficient cabling architecture.

Duplex LC Connector

The EX-SFP-10GE-USR uses a Duplex LC PC/UPC optical connector.

The LC interface is widely used in enterprise and data-center fiber installations and provides a compact connection suitable for high-density fiber deployments.

Optical Monitoring

Juniper specifies that the EX-SFP-10GE-USR supports optical monitoring and Digital Optical Monitoring (DOM).

Monitoring capabilities can help network administrators observe optical parameters and troubleshoot fiber links. Juniper’s documentation notes that monitoring can measure received optical power and display it through the device CLI, while DOM provides support for SFF-8636 monitoring.

Ideal for Data Centers and Enterprise Networks

The short-range characteristics of the EX-SFP-10GE-USR make it especially useful in environments where networking equipment is located relatively close together.

Typical Applications

Data Centers
Connect switches, servers, and aggregation equipment using multimode fiber.

Enterprise Networks
Provide high-speed fiber uplinks between compatible network switches.

Server Rooms
Connect servers and network infrastructure over short fiber distances.

Switch-to-Switch Links
Create high-speed inter-switch connections using compatible multimode fiber.

High-Speed Server Connectivity
Provide 10GbE fiber connectivity between compatible servers and switches.

Compatibility

The EX-SFP-10GE-USR is a Juniper Networks optical transceiver and should be used with supported Juniper platforms and interface modules.

Juniper’s Hardware Compatibility Tool provides the official compatibility information for its transceivers and supported networking platforms. The EX-SFP-10GE-USR is also identified by Juniper as having the common optic equivalent SFPP-10G-USR-C.

Before purchase or installation, verify that the target Juniper switch, router, or interface module supports this specific optic.
