Specifications

Juniper 740‑031981 SFP+ 10GBASE‑LR transceiver SPP5300LR‑J6‑M

The Juniper 740‑031981 is a 10GBASE‑LR SFP+ transceiver module, OEM manufactured by Sumitomo Electric (SPP5300LR‑J6‑M). It delivers 10‑Gigabit Ethernet long‑reach optical connectivity over single‑mode fiber at 1310 nm wavelength with duplex LC interface. It features extended‑temperature performance with case operating temperature ranging from 0°C to +85°C. Hot‑pluggable SFP+ MSA form‑factor, pre‑programmed EEPROM enables native recognition on Juniper EX, QFX, MX, SRX platforms. Supports DDM digital diagnostic monitoring for real‑time optical parameter monitoring.

Typical Applications

✨Enterprise Campus Backbone Uplinks: Connects SFP+ uplink ports on campus access/distribution switches (e.g., EX series) to core layers over OS2 (G.652) single-mode fiber (SMF) up to 10km (backward compatible with OS1).

✨Data Center Inter-Rack & Inter-Building Links: Delivers single-span 10G single-mode fiber connections spanning adjacent data halls, MDF-to-IDF campus closets, or separate buildings up to 10km.

✨Core & Aggregation Networking (MX & QFX Platforms): Pre-programmed with native SFPP-10GE-LR EEPROM code to provide high-density, zero-alarm 10G optical backbone links for MX series line cards (e.g., MIC-3D-10XGE-SFPP, MPCs) and QFX data-center switches (QFX5100, QFX5200).

✨Security Gateway Interconnects & Expansion: Delivers high-bandwidth, secure 10G optical WAN/LAN uplinks for SRX series firewalls (SRX380, SRX1500, SRX4100, SRX4200, SRX4600) with clean syslog recognition.

✨High-Density Hot-Aisle & Elevated-Temp Deployments: Engineered with an extended operating case temperature 0°C to +85°C), making it ideal for fully-populated modular chassis (MX960/480/240, PTX series), hot-aisle racks, and non-climate-controlled remote closets.

✨Carrier Ethernet & MAN Client-Side Hand-Off: Operates as a standard 10GBASE-LR gray optical client interface for OTN/DWDM transponder equipment, supporting 10km point-to-point leased line service hand-offs.
