Quick Answer: Is the TN-XFP-LR1-C51 compatible with my switch?
Pro Disk Network validates every TN-XFP-LR1-C51 against the target switch's published compatibility matrix before shipment. If you let us know your switch model and firmware version, we will confirm fitment and code the module appropriately (Cisco-coded, Juniper-coded, HPE-coded, etc.) at no extra charge.
How fast does the TN-XFP-LR1-C51 ship?
TN-XFP-LR1-C51 orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The TN-XFP-LR1-C51 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
Server Uplink — 10G/25G server-to-leaf uplink — pair with matching DAC or AOC at the host NIC to avoid optic mismatch.
DCI (Data Center Interconnect) — Inter-DC routing or aggregation. LR4/LR8 transceivers for 10–80 km, ER4 for 40 km, ZR4 for coherent long-haul.
Campus Distribution — Catalyst-class campus distribution between IDF and MDF closets. PoE+ where wireless APs and IP phones share infrastructure.
Branch / Edge — Smaller form-factor switches and routers for branch sites. SD-WAN-compatible or static-VPN-attached as the architecture dictates.

Pros & Cons of TN-XFP-LR1-C51
Pros
Matched-pair option for redundant link orders
Cabling and DAC/AOC labels clearly mark optic class
Cons
Third-party optic — some firmware revs require "service unsupported transceiver-type"
Bulk DAC orders may ship LTL on >100-pc reels
Confirm transceiver coding before mixing vendors in the same chassis
Frequently Asked Questions about TN-XFP-LR1-C51
Is the TN-XFP-LR1-C51 a genuine WD part?
Yes. Pro Disk Network sources every TN-XFP-LR1-C51 as factory-original WD inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned WD servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
Is the TN-XFP-LR1-C51 compatible with my switch?
Pro Disk Network validates every TN-XFP-LR1-C51 against the target switch's published compatibility matrix before shipment. If you let us know your switch model and firmware version, we will confirm fitment and code the module appropriately (Cisco-coded, Juniper-coded, HPE-coded, etc.) at no extra charge.
How fast does the TN-XFP-LR1-C51 ship?
TN-XFP-LR1-C51 orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
What is the warranty on the TN-XFP-LR1-C51?
New TN-XFP-LR1-C51 units carry the full WD manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (90 days refurbished). DOA replacement is free within 30 days of receipt.

Optic Coding, Vendor Lock-In, and Multi-Vendor Compatibility
For Cisco IOS, IOS-XE, and NX-OS switches, the TN-XFP-LR1-C51 works out-of-box if coded for Cisco; for Aruba ArubaOS-CX, code for HPE/Aruba; for Juniper Junos, code for Juniper. Pro Disk Network confirms the target vendor coding at order time and applies it before shipping. Misordered coding can be flashed in the field but the lead time is longer than ordering correctly the first time.
Bandwidth Sizing for Spine-Leaf, EVPN-VXLAN, and Hyperconverged Storage
Document optic types and bandwidth in your network drawings: SR-SR for intra-rack, LR-LR for inter-rack and DCI, ZR4 for long-haul coherent. Mismatched optic-distance ratings is the most common cause of intermittent link errors that look like cable problems but aren't.
