JDSU PLRXPL-VC-SH4-HT1 8G Shortwave FC SFP+

The JDSU PLRXPL-VC-SH4-HT1 is a hot-pluggable SFP+ optical transceiver module designed for 8 Gbps Fibre Channel shortwave (SW) 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 multi-rate operation at 8.5 Gbps, 4.25 Gbps, and 2.125 Gbps Fibre Channel, ensuring full backward compatibility with lower-speed FC infrastructure.This transceiver provides reliable short-reach connectivity up to 300 m over OM3 multi-mode fiber (or up to 150–400 m depending on fiber grade such as OM2/OM3/OM4). It complies with the SFP+ Multi-Source Agreement (MSA), FC-PI-4 Fibre Channel Physical Interface standard, and related 8GFC specifications. The module features a duplex LC optical connector and is intended exclusively for multi-mode fiber (MMF) applications. The electrical interface uses a 20-pin SFP+ connector with high-speed differential signals. It operates from a single +3.3 V power supply with low power consumption, typically below 1.5 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 facilitate proactive performance monitoring and fault detection. Additional features include transmitter disable (TX_DISABLE) and loss-of-signal (LOS) indication.
Optical performance meets 8GFC shortwave requirements for jitter tolerance, extinction ratio, and eye mask compliance. The PLRXPL-VC-SH4-HT1 is classified as a Class 1 laser product and complies with RoHS and EMC standards. It is engineered for high port density and reliable operation in storage area networks (SAN).
The transceiver is compatible with a wide range of Fibre Channel switches, directors, and host bus adapters supporting SFP+ shortwave ports from various vendors. It is ideal for intra-rack, intra-row, or short-reach connections in data centers and enterprise SAN environments 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 commercial operating temperatures from 0°C to +70°C and requires adequate airflow for thermal management in high-density deployments. Proper cleaning and inspection of the duplex LC connectors are essential to prevent contamination and maintain optimal link performance.
During operation, the module automatically negotiates the supported Fibre Channel speed (2/4/8 Gbps) 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 OM3 or OM4 fiber for best performance up to 300 m. The module integrates seamlessly with host SAN management systems for remote monitoring of optical parameters and link status.
This shortwave SFP+ transceiver offers a reliable, standards-compliant, and cost-effective solution for building or expanding 8 Gbps Fibre Channel fabrics with short-reach connectivity.
