OC-48/STM-16 SFP 80km SMF Transceiver: 2.67G-SFP-80D

Our EDGEOPTIC 2.67G-SFP-80D 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 single-mode fiber cabling. The 2.67G-SFP-80D module operates at 1550nm 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 DFB (Distributed Feedback) laser for transmission and APD (Avalanche Photodiode) for receiving. Transceiver ensures a 26 dB guaranteed optical link budget, which determines the maximum transmission distance. Over single-mode fiber, the transceiver can reach distances up to 80 kilometers, providing extended long-reach connectivity for metropolitan and regional 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-80D 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 long-haul metropolitan networks, telecommunications backbone rings, regional carrier services, and extended campus networks. The 80km reach capability at 1550nm wavelength maximizes transmission distance in the C-band optical window where fiber exhibits lowest attenuation. The APD receiver technology delivers exceptional -28 dBm sensitivity, critical for reliable long-haul transmission at OC-48/STM-16 speeds. With transmit power ranging from -2 to 3 dBm, the module ensures robust link margins for extended-distance deployments. The module's wavelength bandwidth of 37nm (1528-1565nm) provides operational flexibility for DWDM integration. 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.
