Concise Summary of the Luminent C-Ixx-1250(C)-FDFB-SLCx Transceiver Datasheet

Luminent presents a 1.25 Gbps Single Mode SFF LC Transceiver aimed for high-speed data communications. This small form factor transceiver is part of the C-Ixx-1250(C)-FDFB-SLCx series, integrating features for Gigabit Ethernet and Fiber Channel applications. With duplex LC connectivity, the transceiver operates across a broad wavelength spectrum from 1270 nm to 1610 nm, using a Coarse Wavelength Division Multiplexing (CWDM) Distributed Feedback (DFB) laser.

The device complies with the IEEE 802.3 standard for Gigabit Ethernet and ensures interoperability within multi-sourced environments through its 2×5 pin package. It supports a single +3.3V power supply, LVPECL differential inputs and outputs, and includes a variant with LVTTL signal detection output. Its operating temperature range is from 0 to 70°C, and it meets several safety and environmental standards, including IEC 825, MIL-STD-883, and UL94VO. Humidity resistance is ensured by its compliance with IEC 68-2-3. Moreover, this transceiver pledges compatibility with RoHS and Bellcore GR-468-CORE for reliability.

Key Electrical and Optical Specifications:

The datasheet details the absolute maximum ratings for power supply voltage and output current, including a recommended operating condition with a power supply range of 3.3V to 3.5V and an operating temperature of 70°C. For transmission, parameters such as optical power range, center wavelength, side mode suppression ratio, and others are specified. The transmitter specifications highlight the device’s capability to manage a typical power supply current of 180mA and accommodate various voltage levels compatible with ECL and PECL inputs.

The receiver specifications outline the optical sensitivity and maximum input power with a minimum of -22 dBm and a signal detect functionality with a typical hysteresis of 1 dB. Operating wavelengths range from 1100 nm to 1620 nm. Electrical specifications for the receiver include a power supply current, data output voltages, and signal detect output voltages which are designed to support ECL and LVPECL outputs.

Manufacturing details such as solderability, pin coating (Sn/Pb), and flammability meet industry standards. The transceiver’s robust build accommodates varied humidity levels and includes an uncooled laser diode with Multiple Quantum Well (MQW) structure. These characteristics underscore the transceiver’s reliability and versatility for system integrators and network equipment vendors.
