Description
Streamline your business fiber network with the high-efficiency TP-Link TL-SM321B-2 1000Base-BX WDM Bi-Directional SFP Module. Formulated in compliance with the rigid Small Form Pluggable Multi-Source Agreement (SFP-MSA), this industrial-grade optical transceiver uses advanced Wave Division Multiplexing (WDM) to transmit and receive data concurrently over just a single single-mode fiber strand up to 2 km. It is the ultimate mini-GBIC component for expanding network ranges safely across switches, core routers, and cloud server frames without doubling cable layout costs.
Key Features & Benefits
- Advanced WDM Bi-Directional Technology: Transmits data at 1310 nm and receives at 1550 nm over a single fiber strand, cutting down infrastructure physical installation overhead by up to 50%.
- Extended Range Gigabit Throughput: Achieves highly responsive 1.25 Gbps full-duplex data paths across 9/125 μm Single-Mode Fiber (SMF) spanning up to 2 km (1.24 miles).
- Digital Diagnostic Monitoring (DDM): Complies with SFF-8472 to provide network admins real-time health metrics including interior temperature, voltage performance, laser power, and transceiver loop currents.
- Hot-Swappable Module Convenience: Designed to minimize corporate downtime by allowing operators to plug or pull out modules effortlessly without resetting switch chassis systems.
- Perfect Integration Match: Specifically engineered to work in tandem as a matched terminal pair alongside the TP-Link TL-SM321A-2 module on the opposing node endpoint.
