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)
Juniper-compatible coding for reliable operation with EX, QFX, MX, and SRX systems
All modules are tested and refurbished by our in-house technicians and shipped with a warranty
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.
Popular Juniper Optics SKUs
Below are some of the frequently requested Juniper optics available in this category:
CFP-100GBASE-ER4 – 100G long-range transceiver for up to 40km over SMF

Inventory changes frequently. If you don’t see the exact part number you need, contact our team and we can often source it from our global network of partners.
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.
