JDSU PLRXPL-VI-S24-HW 2.125G Shortwave SFP

The JDSU PLRXPL-VI-S24-HW is a hot-pluggable SFP optical transceiver module designed for multi-rate shortwave 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 data rates including 1.0625 Gbps, 1.25 Gbps, 2.125 Gbps, and up to 2.5 Gbps, making it suitable for 1G/2G Fibre Channel as well as Gigabit Ethernet applications with backward compatibility.This transceiver provides reliable short-reach connectivity up to 500 m (0.5 km) over multi-mode fiber (MMF, typically OM2 or OM3). It complies with the SFP Multi-Source Agreement (MSA) and relevant Fibre Channel and Gigabit Ethernet physical layer specifications. The module features a duplex LC optical connector and is intended exclusively for multi-mode fiber 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) is supported via the two-wire I2C serial interface according to SFF-8472. 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 requirements for jitter tolerance, extinction ratio, and eye mask compliance across supported rates. The PLRXPL-VI-S24-HW 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) and enterprise networking environments.

The transceiver is compatible with a wide range of SFP-enabled switches, routers, and host bus adapters from various vendors supporting shortwave 850 nm modules. It is ideal for intra-rack or short-reach connections in data centers, campus networks, and SAN fabrics 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 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 module automatically negotiates the supported data rate 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 up to 500 m. The module integrates seamlessly with host management systems through standard SNMP or CLI for remote monitoring of optical parameters and link status.

This shortwave SFP transceiver offers a reliable and cost-effective solution for short-reach multi-rate optical connectivity in Fibre Channel and Gigabit Ethernet environments.
