RAD FTM-3012C-SLG SFP Transceiver

The RAD FTM-3012C-SLG is a hot-pluggable SFP (Small Form-factor Pluggable) optical transceiver module designed for Gigabit Ethernet and compatible applications in RAD and third-party multiservice platforms. It provides a bidirectional optical interface operating at data rates up to 1.25 Gbit/s, with dual-rate support for 1.25 Gbit/s and 1.0625 Gbit/s (Gigabit Ethernet and 1G Fibre Channel).This module operates at a nominal wavelength of 1310 nm using a Fabry-Perot (FP) laser transmitter and a PIN photodiode receiver. It is optimized for single-mode fiber (SMF 9/125 µm) with a typical transmission distance of up to 10 km (some variants list up to 20 km depending on link budget and fiber quality). The optical specifications align with 1000BASE-LX requirements, delivering reliable performance with low bit error rates (better than 10⁻¹²) over the specified reach. Transmitter output power and receiver sensitivity meet standard intermediate-reach budgets for metro access and enterprise links.
The FTM-3012C-SLG complies with the SFP MSA (INF-8074i), IEEE 802.3z 1000BASE-LX, and related standards. It supports serial data transmission with low jitter generation and high extinction ratio. The module features a spring-latch mechanism for secure and easy insertion/removal. Digital diagnostic monitoring (DDM/DOM) may be available depending on the exact revision, allowing access to real-time parameters such as optical power, temperature, and voltage.
Optical connectivity is provided through a duplex LC connector. Key operational features include Loss of Signal (LOS) detection and assertion, automatic laser shutdown (ALS) for Class 1 eye safety compliance, and hot-swap support. The transceiver uses the standard 20-pin SFP electrical interface with a 3.3 V power supply and low power consumption (typically below 1 W), enabling high-density port configurations in switches, routers, and optical transport equipment.
Environmental specifications follow standard carrier and enterprise requirements with a commercial operating temperature range of 0°C to +70°C, high humidity tolerance, and built-in ESD protection. This SFP is primarily used for point-to-point Gigabit Ethernet links, fiber infrastructure in access networks, or as uplink/tributary interfaces in RAD equipment and compatible platforms.
The module integrates with network management systems for monitoring. Installation requires standard fiber optic cleaning procedures, correct Tx/Rx polarity, and adherence to minimum bend radius guidelines for patch cords. The RAD FTM-3012C-SLG (often based on Fiberxon/Source Photonics design) offers a reliable, compact, and cost-effective solution for 1.25 Gbit/s optical transport over single-mode fiber up to 10 km.
