Juniper 10GBASE-T Copper SFP+ Transceiver — 30m RJ-45

The Juniper JNP-SFPP-10GE-T is a 10GBASE-T copper SFP+ transceiver delivering 10GbE over Cat6a copper cabling up to 30m via RJ-45 connector — Juniper-coded for use in Juniper QFX, EX, MX, and SRX platforms requiring 10G copper connectivity in SFP+ port slots without fiber infrastructure.

Key Features

• 10GBASE-T copper SFP+ for 10GbE over Cat6a in Juniper SFP+ port slots
• RJ-45 connector enabling 10G copper connectivity without fiber cabling or media converters
• 30m Cat6a reach for in-rack and short cross-row 10G copper links
• Juniper-coded (JNP-SFPP-10GE-T) for plug-and-play compatibility on Juniper platforms
• Auto-negotiation supporting 1GbE and 10GbE speeds for flexible copper connectivity

Product Specifications

• Part Number: JNP-SFPP-10GE-T
• Manufacturer: Juniper Networks
• Form Factor: SFP+
• Speed: 10GbE (10GBASE-T)
• Connector: RJ-45
• Cable Type: Cat6a copper (30m), Cat6 (up to 30m reduced distance)
• Max Distance: 30m (Cat6a)

Transceiver & Interface Specifications

• Auto-negotiation: Yes (1G/10G)
• Duplex: Full duplex
• Power Consumption: Typically 2.5W (higher than optical SFP+ due to 10GBASE-T PHY)
• DDM/DOM: No (copper transceiver)
• Operating Temperature: 0°C to 70°C (commercial)

Use Cases

• 10GbE copper server uplinks to Juniper QFX/EX switches via Cat6a in SFP+ ports
• Connecting 10GBASE-T NIC-equipped servers to Juniper optical SFP+ switch ports
• Short in-rack 10G copper links where fiber is not available or practical
• Flexible 10G copper connectivity in Juniper MX or SRX platforms for short-reach copper links

Compatibility

• Compatible with Juniper QFX, EX, MX, and SRX platforms with SFP+ 10G ports
• Requires Cat6a cable for full 30m 10GBASE-T reach (Cat6 limits reach to ~20m at 10G)
• IEEE 802.3an 10GBASE-T compliant
• Not compatible with SFP (1G) slots — requires SFP+ capable port

Frequently Asked Questions

Why does the JNP-SFPP-10GE-T consume more power than optical SFP+ modules?

10GBASE-T copper transceivers include a full 10G BaseT PHY chip that performs the complex DSP signal processing required for 10G transmission over copper — typically consuming 2–3W compared to ~1W for optical SFP+ modules. Verify your switch's per-port power budget before populating many JNP-SFPP-10GE-T modules.

What cable category is required for full 30m reach at 10GbE?

Cat6a (Augmented Category 6) is required for reliable 10GBASE-T operation at 30m. Standard Cat6 cable supports 10GBASE-T at reduced distances of up to approximately 20m — for full 30m reach, Cat6a or better cabling is required.

Can the JNP-SFPP-10GE-T auto-negotiate to 1GbE if the connected device is 1G only?

Yes — the JNP-SFPP-10GE-T supports auto-negotiation between 1GbE and 10GbE speeds. When connected to a 1GBASE-T device, the link will negotiate to 1GbE operation, allowing flexible connectivity to both 1G and 10G copper-equipped devices.

The Juniper JNP-SFPP-10GE-T extends 10GbE connectivity to copper-cabled environments — enabling Cat6a-based 10G links in Juniper SFP+ optical port slots for server uplinks, cross-connects, and short-reach copper deployments where fiber is impractical or unavailable.
