SFP+ SR-DDM 10Gb/s Module for 10G Ethernet Networks

The SFP+ SR DDM module is a 10Gb/s optical transceiver for inter-rack connections and 10G Ethernet uplinks in enterprise networks and data center environments. It is the standard deployment choice for multimode fiber uplinks in switch stacks, aggregation layers, and inter-switch connections at distances up to 300 meters.

The transceiver operates at 850nm over duplex multimode LC fiber, supporting 10Gb/s throughput in accordance with IEEE 802.3ae 10GBASE-SR. The 300m transmission range covers typical rack-to-rack, floor-to-floor, and adjacent-building links in OM3/OM4 cabling infrastructures. DDM (Digital Diagnostic Monitoring) enables real-time visibility into key optical parameters — temperature, supply voltage, laser bias current, transmitted and received optical power — directly through the switch management interface.

Built in standard SFP+ form factor, the module is compatible with Cisco equipment and with switches and routers from other vendors accepting generic SFP+ transceivers. It installs into any SFP+ slot without hardware configuration changes and integrates directly into existing LC duplex optical patch infrastructures.

Recommended for 10G uplinks in access and aggregation switches, inter-rack fiber connections in data centers, multimode optical infrastructure expansion, and cost-effective replacement of OEM transceivers with compatible alternatives. Suited for network administrators and integrators managing 10G Ethernet infrastructures over multimode fiber.
