BrightStar Systems carries a deep inventory of used and refurbished Juniper optics and cables to support EX, QFX, MX, SRX, and other Juniper platforms. This Juniper Optics & Cables category is your central hub for transceivers and cabling across multiple form factors, including CFP/CFP2, QSFP, SFP, SFP+, and XFP, all tested and backed by our in-house warranty.

Whether you’re building a new data center fabric, extending 100G long-haul links, or adding simple 1G/10G uplinks to campus switches, we provide OEM-coded Juniper optics at a fraction of new hardware cost. Every module is inspected, tested, and shipped ready for plug-and-play deployment.

Juniper Optics & Cables Overview

This category brings together the full stack of Juniper transceivers and optical cabling used across routers, switches, and security platforms:

CFP/CFP2 optics for 40G and 100G long-range transport

QSFP optics (40G) for spine, aggregation, and inter-switch links

SFP optics for 1G/FE access and uplinks

SFP+ optics for 10G data center and aggregation

XFP optics for legacy 10G applications

Most optics in this category are coded for Juniper and are commonly deployed with EX Series campus switches, QFX Series data center switches, MX Series edge routers, and SRX Series firewalls and secure gateways.

Key Features of Juniper Optics & Cables

Wide range of speeds – 1G, 10G, 40G, and 100G transceivers for access, aggregation, and core

Short- and long-reach options – SR, LR, ER, and ZR modules for everything from in-rack to long-haul links

Multiple form factors – CFP/CFP2, QSFP, SFP, SFP+, and XFP optics for different platforms and slot types

Support for single-mode and multi-mode fiber with various connector types (LC, SC, MPO/MTP)

If you’re planning a larger refresh that includes switches and routers, you can pair this category with our dedicated Juniper hardware hub: Juniper Routers & Switches.

Juniper Optics Form-Factor Breakdown

CFP & CFP2 (40G/100G Transport)

Juniper CFP/CFP2 optics are designed for high-capacity 40G and 100G links, often used for data center interconnects, metro links, and long-haul transport. Modules like the CFP-100GBASE-ER4 and CFP2-100G-LR4-D deliver long-range connectivity over single-mode fiber for up to tens of kilometers.

QSFP (40G Aggregation & Spine)

Juniper QSFP optics support 40G links between leaf and spine switches, or from switches to routers. Models like JNP-QSFP-40G-LR4 extend 40G connectivity beyond the rack for aggregation, core, and data center interconnect use cases.

SFP (1G/FE Access & Uplinks)

Juniper SFP optics provide flexible 100M and 1G connectivity for access and aggregation layers. Common SKUs include EX-SFP-1FE-LH, EX-SFP-GE10KT13R14, and EX-SFP-1GE-SX-CS, often used with EX Series switches.

SFP+ (10G Data Center & Aggregation)

Juniper SFP+ optics are widely used for 10G server uplinks, aggregation, and inter-switch links. Transceivers like QFX-SFP-10GE-USR and SFPP-10GE-ZR support short-range and long-range 10G connectivity for QFX and MX platforms.

XFP (Legacy 10G Applications)

Juniper XFP optics support legacy 10G applications where XFP slots are still in use, helping extend the life of older platforms while keeping optics spend under control.

Use Cases & Deployment Scenarios

Data center fabrics – 10G SFP+ and 40/100G CFP/CFP2/QSFP optics for leaf–spine architectures

Campus and branch networks – 1G SFP and 10G SFP+ uplinks for EX and QFX switches

Metro and long-haul transport – ER and ZR optics for 40G/100G long-distance links

Service provider edge – high-density optics for MX Series routers and aggregation points

Lab and test environments – cost-effective optics for non-production and validation networks

By using pre-owned Juniper optics instead of brand-new OEM modules, many customers reduce optics spend by 50% or more while maintaining reliability and standards-compliant performance.

Compatibility with Juniper Routers & Switches

Juniper optics and cables in this category are commonly deployed with:

EX Series switches (EX3200, EX3400, EX4300, EX4400, EX4600, EX4650, and more)

QFX Series switches (QFX3500, QFX5100, QFX5120, QFX5200, QFX10000)

MX Series routers (MX204, MX480, MX960, and others)

SRX Series gateways and firewalls for routed and secured links

If you share your switch or router model and the distances you need to cover, we can help you choose the correct form factor, wavelength, and reach. We can also verify compatibility against Juniper datasheets and deployment guides before you order.

Lifecycle & EOL/EOS Optics

Many customers rely on EOL/EOS Juniper optics to keep stable networks running without a full platform refresh. BrightStar Systems specializes in sourcing older CFP, XFP, and SFP modules that are no longer widely available through OEM channels.
