JDSU PLRXPL-VE-SG4-62-N 4G Shortwave FC SFP

The JDSU PLRXPL-VE-SG4-62-N is a hot-pluggable SFP optical transceiver module designed for multi-rate Fibre Channel applications. It operates at a nominal wavelength of 850 nm using a VCSEL (Vertical Cavity Surface Emitting Laser) transmitter and a PIN photodiode receiver. The module supports triple-rate operation at 1.0625 Gbps, 2.125 Gbps, and 4.25 Gbps Fibre Channel, providing full backward compatibility with lower-speed FC infrastructure while delivering high-performance shortwave (SW) connectivity.This transceiver supports transmission distances up to 500 m on OM3 multi-mode fiber or up to 300–400 m on OM2/OM3 MMF depending on the specific data rate and fiber quality. It complies with the SFP Multi-Source Agreement (MSA), FC-PI-2/FC-PI-3 Fibre Channel Physical Interface standards, and related multi-rate specifications. The module features a duplex LC optical connector and is intended exclusively for multi-mode fiber (MMF) applications. The electrical interface uses a standard 20-pin SFP connector with high-speed differential CML signals. It operates from a single +3.3 V power supply with low power consumption, typically below 1 W.
Digital diagnostic monitoring (DDM/DOM) functions are implemented according to SFF-8472 via the two-wire I2C serial interface. This enables real-time monitoring and reporting of key parameters including transmitted optical power, received optical power, laser bias current, supply voltage, and module temperature. Programmable warning and alarm thresholds support proactive performance monitoring and fault detection. Additional features include transmitter disable (TX_DISABLE) and loss-of-signal (LOS) indication.
The design ensures compliance with Fibre Channel jitter tolerance, extinction ratio, and eye mask requirements for all supported rates. The PLRXPL-VE-SG4-62-N is classified as a Class 1 laser product and complies with RoHS, EMC, and ESD standards. It is engineered for superior EMI performance and high port density in storage area network (SAN) environments.
The transceiver is compatible with a wide range of Fibre Channel switches, directors, and host bus adapters supporting SFP ports from JDSU/VIAVI and other vendors. It is ideal for short-reach connections in data centers, enterprise SANs, and high-performance computing clusters requiring reliable 1G/2G/4G Fibre Channel links over existing multi-mode fiber infrastructure.
Installation is simplified by the hot-pluggable SFP form factor, allowing insertion or removal without powering down the host equipment. The module supports extended operating temperatures from -20°C to +85°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 PLRXPL-VE-SG4-62-N automatically negotiates the supported Fibre Channel speed with the connected device and provides calibrated digital diagnostic data for accurate reporting. Recommended fiber patch cables are duplex multi-mode LC-to-LC with OM2 or OM3 fiber for maximum reach and performance. The module integrates seamlessly with host SAN management systems through standard interfaces for remote monitoring of optical parameters and link status.
This shortwave SFP transceiver offers a reliable, cost-effective, and standards-compliant solution for building or expanding multi-rate Fibre Channel fabrics with short-reach connectivity.
