What is the maximum distance supported by the 813874-B21 at 10 Gbps?

It supports data transmission distances up to 30 meters using Cat6a or Cat7 copper cabling.

What type of connector interface does this module use?

It is equipped with a standard, premium-grade RJ45 interface for standard copper patch cords.

Does the 813874-B21 support hot-plugging?

Yes, it features a hot-pluggable SFP+ footprint, allowing installation or replacement without powering down host devices.

Is the 813874-B21 compatible with major networking brands?

Yes, it is built to strict SFP+ MSA standards to ensure excellent interoperability with leading switches and routers.

Hi there, our server room runs a hybrid environment with Cisco Nexus, Ubiquiti UniFi, and some older Netgear ProSafe switches. Can this LP-RJ45TG-3YC module auto-negotiate properly across all these different vendor slots? Does it strictly follow SFF-8431 and SFP+ MSA specs? We had link flapping issues with generic 10GBASE-T transceivers before.

Yes, absolutely. The LINK-PP LP-RJ45TG-3YC is engineered strictly based on the SFP+ MSA, SFF-8431, and SFF-8432 standards, incorporating an advanced premium PHY chip. It is fully programmed for broad multi-vendor compatibility (including Cisco, Ubiquiti, Netgear, Mikrotik, etc.) and supports standard Auto-Negotiation for 10GBASE-T Ethernet links. The built-in RX_LOS (Loss of Signal) feature ensures rapid link status monitoring, preventing the common link-flapping issues seen in lower-tier unbranded modules.

We are looking to upgrade our university campus network architecture and need to batch-deploy around 150 units of these RJ-45 transceivers into our Top-of-Rack setup. Is there a B2B volume pricing tier or corporate discount available? Also, what's the lead time for this quantity to the West Coast US

Thank you for reaching out! For enterprise-level batch-deployments of 150+ units, we definitely provide tiered wholesale discounts and can offer free expedited shipping (as we waive shipping costs for orders over $600). Since the LP-RJ45TG-3YC is currently in 'Active' status and mass-produced in our automated production workshops, we have high stock availability. Standard shipping to the US West Coast typically takes 3-5 business days via DHL/FedEx. Please contact our B2B sales team directly for an official commercial invoice quote.

The spec table says this module is rated for Commercial Temperature (0°C to +70°C). We need to place several 10G links in unconditioned outdoor cabinets and roadside base station backhaul units where internal housing temps regularly exceed 75°C during summer. Do you offer an Industrial-Grade version of this copper transceiver?

Great question! This specific model (LP-RJ45TG-3YC) is optimized for standard commercial environments like indoor data centers and enterprise server rooms (0°C to +70°C). However, for harsh deployments like outdoor cabinets or cellular base station backhauls, LINK-PP does manufacture customized Industrial-Grade (-40°C to +85°C) 10GBASE-T SFP+ copper modules with enhanced EMC shielding and ruggedized silicon. Please let our tech team know your exact thermal limits, and we will match you with the corresponding industrial-grade part number.

Can we run this module using standard Cat6 copper patch cables, or is Cat6a/Cat7 strictly mandatory to hit the full 30-meter reach? Our existing structured cabling is a mix of shielded and unshielded Cat6. Will the performance degrade significantly at 10 Gbps speeds?

To guarantee full, error-free 10 Gbps throughput at the maximum 30-meter transmission distance, we highly recommend using high-quality Cat6a or Cat7 (SFTP/FTP) shielded copper cabling. Standard Cat6 cables can work for shorter distances (typically up to 15-20 meters depending on environmental electromagnetic interference and cross-talk). For high-density enterprise routing, sticking to IEEE 802.3an compliant Cat6a or better ensures stable link initialization and optimal signal integrity across the entire copper interface.
