HG Genuine MXPD-033S-F 155Mb/s 1310nm 15km SFP

The HG Genuine MXPD-033S-F is a hot-pluggable SFP optical transceiver module designed for 155 Mbps data transmission over single-mode fiber. It operates at a nominal wavelength of 1310 nm using a Fabry-Perot (FP) laser transmitter and a PIN photodiode receiver. The module supports reliable transmission distances up to 15 km and complies with the SFP Multi-Source Agreement (MSA), SFF-8472 digital diagnostic specifications, and ITU-T G.957 S-1.1 application code for STM-1/OC-3 interfaces.This transceiver is optimized for the 155.52 Mbps STM-1/OC-3 line rate with NRZ encoding and is also suitable for other 100–155 Mbps applications. It features duplex LC optical connectors and is intended for use with ITU-T G.652 single-mode fiber (SMF). The electrical interface consists of a 20-pin SFP connector with differential CML signals. The module operates from a single +3.3 V power supply with low power dissipation, typically below 1 W.
Digital diagnostic monitoring (DDM) functions are implemented with external calibration via the two-wire I2C serial interface. This enables real-time monitoring and reporting of critical operating parameters including transmitted optical power, received optical power, laser bias current, supply voltage, and module temperature. Programmable warning and alarm thresholds support proactive fault detection and performance management. Additional features include transmitter disable (TX_DISABLE), loss-of-signal (LOS) output, and receiver loss-of-signal indication.
Optical performance specifications include average transmitter output power from -15 dBm to -8 dBm and receiver sensitivity of -28 dBm or better, providing a sufficient link budget for 15 km reach on single-mode fiber with adequate margin. The design meets relevant standards for jitter tolerance, extinction ratio, and eye mask compliance. The MXPD-033S-F is classified as a Class 1 laser product and complies with RoHS and EMC requirements.
The transceiver is compatible with Huawei and other SFP-enabled platforms supporting 155 Mbps interfaces, including SDH/SONET multiplexers, optical transmission equipment, routers, and switches used in access networks, FTTx deployments, and metro applications. It is particularly suited for STM-1/OC-3 point-to-point links requiring 15 km single-mode fiber reach.
Installation is simplified by the hot-pluggable SFP form factor, allowing insertion or removal without powering down the host equipment. The module supports commercial operating temperatures from 0°C to +70°C and requires minimal airflow for thermal management. Proper cleaning and inspection of the duplex LC connectors are essential to prevent contamination and maintain optimal link performance.
During operation, the MXPD-033S-F provides calibrated digital diagnostic data for accurate reporting and integrates seamlessly with host management systems through standard SNMP or CLI interfaces. Recommended fiber patch cables are duplex single-mode LC-to-LC with low insertion loss. The module ensures reliable performance in carrier-grade and enterprise environments while maintaining full MSA compliance and Huawei ecosystem compatibility.
