OC-48/STM-16 SFP 300m MMF Transceiver: 2.67G-SFP-300D

Our EDGEOPTIC 2.67G-SFP-300D is a multi-vendor compatible OC-48/STM-16 SFP dual-fiber optical module designed for high-speed SONET/SDH and Gigabit Ethernet applications operating over multimode fiber cabling. The 2.67G-SFP-300D module operates at 850nm wavelength for transmission and reception, with data rates from 0.1 to 2.67 Gbps and supports multiple protocol standards and applications. Our OC-48/STM-16 SFP transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) for transmission and PIN photodiode for receiving. Transceiver ensures a 7.5 dB guaranteed optical link budget, which determines the maximum transmission distance. Over multimode fiber, the transceiver can reach distances up to 300 meters, providing short-reach connectivity for data center and enterprise network deployments. However, distance is just an indicative parameter calculated for comfort of identification – eventually we calculate distance taking into account minimal optical budget and average attenuation of optical cabling in industry.

2.67G-SFP-300D compatible OC-48/STM-16 module is hot-pluggable SFP with duplex LC/UPC connectors as an optical interface. The electrical interface conforms to INF-8074i MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems supporting multiple vendor equipment platforms. Our OC-48/STM-16 SFP transceiver can be encoded to be compatible and successfully operate in different 80+ brands of equipment. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality providing real-time information including transmitted and received optical power levels, module temperature, bias current, and supply voltage. This diagnostic data is available via MSA-compatible EEPROM interface and enables monitoring of transceiver operational parameters. The module operates within a 0 to 70°C temperature range, with appropriate thermal considerations for sustained operation in controlled network environments.

Standards compliance includes comprehensive multi-protocol support: SDH/SONET for STM-1 (155Mbps), STM-4 (622Mbps), and STM-16 (2.488 Gbps); Gigabit Ethernet at 1.25 Gbps; Fiber Channel supporting both 1G (1.0625 Gbps) and 2G (2.125 Gbps); and OTN applications including ODU0 (1.244Gbps), ODU1 (2.498Gbps), and OTU1 (2.66Gbps). The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for compatibility. Our OC-48/STM-16 SFP transceiver is CE/RoHS certified, and it is compliant with Class 1 FDA and IEC60825-1 laser safety standards.

Typical applications are data center interconnects, storage area networks, telecommunications access rings, and high-speed campus backbones. The multi-rate capability from 100Mbps to 2.67Gbps provides exceptional flexibility for mixed-speed deployments and network migration paths. The 850nm VCSEL technology delivers reliable performance for short-reach applications while maintaining low power consumption. The module's wavelength bandwidth of 20nm (840-860nm) ensures stable operation across temperature variations. Because our focus is providing top quality service, we are performing serious quality checks before delivery of our products. As a result, we do optical parameter measurements, connector cleanness tests and SFP transceiver EEPROM memory data validation tests.
