HYTOPTODEVICE Arista SFP-10G-LXRBD-U Compatible 10GBASE-BX20-U SFP+ BiDi 1270nm-TX/1330nm-RX 20km DDM LC SMF Optical Transceiver Module

   The HYTOPTODEVICE Arista SFP-10G-LXRBD-U compatible series provides a high-reliability 10G single-strand fiber solution for medium-range network extensions. Specifically designed for high-density data center fiber optimization, these 20km 10G SFP+ BiDi transceivers enable stable 10Gbps communication over a single strand of single-mode fiber (SMF). This series is a cost-effective fiber migration tool for operators looking to double their existing fiber capacity without the expense of new trenching.Fully compliant with SFP+ MSA SFF-8431 and rigorously tested for Arista EOS compatibility, these modules offer seamless integration with Arista 7050X, 7060X, and 7280R series switches. Featuring low-latency 10G BiDi optics and integrated Digital Optical Monitoring (DOM), the LXRBD series ensures that IT teams can monitor real-time link health and optical power levels, making them the preferred choice for Data Center Interconnect (DCI) and metropolitan enterprise networks.

Compatibility and Supported Device

The HYTOPTODEVICE SFP-10G-LXRBD-U/D is pre-coded for "Plug-and-Play" performance with:

• Arista 7280R/R2/R3 Series: Universal Leaf and Spine platforms for long-distance routing.

• Arista 7050X3 Series: High-performance data center switches (e.g., 7050SX3-48YC8).

• Arista 7060X Series: Optimized for cloud-scale leaf-spine architectures.

• Arista 7150S Series: Ultra-low latency switches for financial and trading applications.

• Metropolitan Area Network (MAN) Connectivity: A perfect 10G single-strand fiber solution for connecting corporate headquarters to regional offices or satellite data centers within a 20km radius.

• Medium-Range Data Center Interconnect (DCI): Establishing high-speed low-latency 10G BiDi optics links between separate data center halls located in the same city to enable real-time data replication and disaster recovery.

• Enterprise Campus Backbone Expansion: Bridging large campus networks where the distance exceeds 10km, allowing for a cost-effective fiber migration by utilizing existing single-core fiber infrastructure.

• ISP Edge Aggregation: Providing reliable 10G SFP+ 20km BiDi backhaul from remote neighborhood aggregation points to the central office (CO) using Arista 7280R series routers.

• Fiber-Constrained Urban Links: Doubling the capacity of leased dark fiber in urban environments where the cost of additional fiber strands is prohibitively high.

FAQ for  Arista SFP-10G-LXRBD-U Compatible SFP+BiDi Transceivers

Q1: What is the difference between Arista BX (10km) and LXR (20km) modules? A: The LXR series (SFP-10G-LXRBD) features a higher optical power budget designed for distances up to 20km, whereas the standard BX series is limited to 10km. This makes it ideal for larger campuses and inter-city links.

Q2: Do I need to buy these in pairs? A: Yes. To establish a link, you must pair the Upstream (U) module (1270nm-TX/1330nm-RX) with the Downstream (D) module (1330nm-TX/1270nm-RX).

Q3: Is the Arista "service unsupported-transceiver" command required? A: No. HYTOPTODEVICE modules are pre-programmed with Arista-specific SPD data. Your switch will recognize them as native Arista optics, ensuring they work immediately without any manual overrides in EOS.

Q4: Can these 20km modules be used for very short links (e.g., 500 meters)? A: Yes. The high dynamic range of our lasers prevents receiver saturation on shorter spans, though monitoring the RX power via DOM is always recommended during installation to ensure optimal levels.

Q5: How do I check the signal quality on an Arista switch? A: You can use the command show interfaces ethernet [port] transceiver in the Arista CLI to view real-time Digital Optical Monitoring (DOM) data, including TX/RX power, temperature, and voltage.
