2.5GBASE-LX SFP Transceiver | 1310nm 2km SMF LC DOM | SFP MSA Compliant | OEM/ODM, SFP-2.5G-LR13-2

Features

2.5G High-Speed Transmission with DFB Laser Technology

The SFP-2.5G-LR13-2 delivers reliable 2.5Gbps data transmission over single-mode fiber (SMF) G.652 up to 2 kilometers. Featuring a 1310nm DFB (Distributed Feedback) laser, this transceiver provides: Stable optical output across temperature variations (0°C to 70°C), Narrow spectral width for minimal chromatic dispersion, Superior side-mode suppression for error-free transmission, Link budget of > 8.5 dB to accommodate connector losses and fiber aging, This ensures low bit error rate (BER < 10^-12) performance for bandwidth-intensive applications such as enterprise campus backbones, data center interconnects, and service provider metro networks.

Advanced Digital Diagnostic Monitoring (DDM/DOM) for Proactive Network Management

Built-in Digital Diagnostic Monitoring, compliant with SFF-8472 v9.5, We have achieved predictive maintenance, rapid fault isolation, and proactive network optimization, significantly reducing mean time to repair (MTTR) and improving overall network availability. Network administrators can monitor link health in real-time through standard SNMP queries or switch CLI commands.

Comprehensive Standards Compliance for Guaranteed Interoperability

The SFP-2.5G-LR13-2 is engineered to meet the most stringent industry specifications, ensuring seamless integration into any network environment: SFP MSA (INF-8074i): Full mechanical and electrical compatibility with all standard SFP cages, ITU-T G.957: Optical interface specifications for SDH/SONET systems (STM-16/OC-48), GR-253-CORE: SONET transport systems requirements, SFF-8472 v9.5: Digital Diagnostic Monitoring (DDM/DOM) specifications, FC-PI v2.0: Fibre Channel physical interface standards for 2x Fibre Channel applications, This multi-standard compliance guarantees broad interoperability with switches, routers, and media converters from Cisco, Juniper, Huawei, Arista, Extreme Networks, and other leading manufacturers, simplifying procurement and reducing integration time.

Backward Compatibility for Seamless Network Migration

The SFP-2.5G-LR13-2 is designed to protect your existing infrastructure investments: 1G backward compatibility: Operates in Gigabit Ethernet (1000BASE-LX) applications with auto-negotiation, 10G infrastructure ready: Can be used in 10G-rated fiber plants for future upgrades, Legacy form factor support: Compatible with XENPAK, X2, and XFP interfaces when used with appropriate media converters or host adapters, This flexibility allows network architects to implement phased upgrades without complete infrastructure overhauls, reducing capital expenditure and extending the useful life of existing equipment.

Compact Hot-Pluggable Design for Maximum Network Uptime

Fully compliant with SFP MSA mechanical specifications, the module features: Standard SFP footprint: Fits any standard SFP cage, enabling high-density deployments, Hot-swappable capability: Insert or remove modules without powering down the system, Metal enclosure: Provides low EMI and robust mechanical protection, Dust-proof design: Includes protective dust cap for unused ports, This hot-swappable capability is essential for carrier-grade networks, data centers, and enterprise environments where every minute of downtime translates into significant operational and revenue loss.
