RUIJIE XG-SFP-ER-SM1550 - 10G SFP SM

The Ruijie XG‑SFP‑ER‑SM1550 is a high‑performance 10GBASE‑ER single‑mode fibre SFP+ transceiver engineered for long‑reach 10‑Gigabit Ethernet connectivity across demanding enterprise, campus and metro networks. Built to the SFP+ MSA form factor, it provides a cost‑effective, energy‑efficient and standards‑compliant solution for switches, routers, servers and optical transport platforms requiring stable 10G uplinks over extended fibre distances.

Delivering 10.3125 Gbps full‑duplex throughput, the XG‑SFP‑ER‑SM1550 operates at a 1550 nm wavelength using a DFB laser transmitter and PIN photodiode receiver, ensuring excellent optical stability and long‑distance signal integrity. It supports link lengths of up to 40 km over single‑mode fibre (SMF) using a duplex LC/UPC connector, fully aligned with IEEE 802.3ae 10GBASE‑ER optical specifications.

The module conforms to key industry standards including IEEE 802.3ae, SFF‑8431, SFF‑8432, SFP+ MSA, CE, and RoHS, ensuring broad interoperability with Ruijie switches and other SFP+‑enabled equipment. It also supports Digital Diagnostics Monitoring (DDM/DOM), providing real‑time visibility into optical power, temperature, voltage, laser bias current and link health — enabling proactive maintenance and rapid fault isolation.

Engineered for dependable operation, the XG‑SFP‑ER‑SM1550 is hot‑pluggable, allowing installation or replacement without service interruption. It operates within a commercial temperature range of 0°C to +70°C, with low power consumption of ≤ 1.5 W, making it ideal for high‑density data‑centre racks and campus distribution layers where thermal efficiency is critical.

Optical performance is robust, with typical transmit power ranging from –4.7 dBm to +4 dBm, extinction ratio ≥ 3 dB, receiver sensitivity down to –14.1 dBm, and overload tolerance around –1 dBm. These values ensure stable operation across varying fibre conditions and long‑distance attenuation scenarios, matching industry‑standard ER optics.

Safety and compliance are ensured through Class 1 laser certification, FDA/IEC‑60825, and RoHS adherence, guaranteeing safe operation and environmentally responsible manufacturing. With a BER of 1.0E‑12, the transceiver delivers highly reliable performance suitable for mission‑critical enterprise, metro and backbone networks.

Compact, efficient and fully standards‑compliant, the XG‑SFP‑ER‑SM1550 is ideal for long‑range 10G fibre uplinks in campus networks, metro access layers, data centres, server rooms and enterprise switching environments. It provides a dependable, plug‑and‑play solution for expanding high‑speed optical connectivity while maintaining excellent performance, low latency and long‑term reliability.
