The 155Mbps SFP Optical Transceiver is a high-performance module capable of transmitting optical signals over distances of up to 120 kilometers on single-mode fiber (SMF). It is housed in an SFP package with an LC connector and features a 1550nm DFB laser paired with a PIN photo detector. Its design adheres to IEC-60825 laser safety standards and is compatible with RoHS, ensuring both safety and environmental compliance. With a single power supply operating at +3.3V and LVPECL-compatible data input/output interfaces, this transceiver provides reliable integration into Ethernet, telecom, and Fiber Channel applications.
The module’s robust design allows it to function in a variety of environments. It supports a supply voltage range from 3.15V to 3.45V and operates in temperatures ranging from 0°C to +70°C in commercial settings, and -40°C to +85°C for industrial use. With low electromagnetic interference (EMI) and excellent electrostatic discharge (ESD) protection, it offers dependable performance in high-demand and sensitive network scenarios. It also features a low power dissipation of 1W, maintaining efficient energy use at a data rate of 155Mbps.
The transceiver’s optical performance is engineered for precision and reliability. The transmitter operates with a center wavelength of 1550nm, an average output power ranging from 0dBm to 5dBm, and an extinction ratio between 12dB and 18dB. The receiver section supports a wide center wavelength range from 1260nm to 1620nm, with a sensitivity of -36dBm and a maximum overload of -3dBm. Key optical features include a jitter tolerance of 0.43 UI and compliance with IEEE 802.3u and ANSI Fiber Channel standards for optical eye diagrams, ensuring high-quality signal transmission.
In terms of electrical characteristics, the transceiver is designed for versatility and compatibility with host systems. Its differential impedance for both transmitter and receiver sections is maintained at 100Ω, with a data input swing differential of 500mV to 2400mV for the transmitter and 370mV to 2000mV for the receiver. Clear voltage thresholds for TX Disable and Rx_LOS functionalities ensure seamless operation, further enhancing its usability across diverse network architectures.
This transceiver represents a cutting-edge solution for long-distance optical communications. Its adherence to strict performance and safety standards, coupled with its advanced optical and electrical specifications, make it an excellent choice for professionals seeking reliable and efficient networking hardware.
