OSFP-200G-2LR4: frequently asked questions
What is the Arista OSFP-200G-2LR4?
The Arista OSFP-200G-2LR4 is a OSFP 2 × 100GBASE-LR4 module from Arista Networks for 2 × 100 Gbps links. It plugs into a OSFP port on an Arista switch and is used for 200G fabrics, dual-100G aggregation and high-density 25G/10G fan-out.
What is the maximum distance of the OSFP-200G-2LR4?
Arista specifies the OSFP-200G-2LR4 for 10 km over two pairs of duplex single-mode fiber (2 × 100GBASE-LR4).
What are the transmit and receive power levels of the OSFP-200G-2LR4?
Per Arista's published optics data sheet, the OSFP-200G-2LR4 transmits −4.3 to +4.5 dBm/lane and receives −10.6 to +4.5 dBm/lane.
Which fiber and connector does the OSFP-200G-2LR4 need?
The OSFP-200G-2LR4 uses a 2 × duplex LC connector on 2 pairs duplex single-mode, at LAN-WDM 4 lambda per link. Both ends of the link must use the same optical standard.
Is the OSFP-200G-2LR4 compatible with my Arista switch?
It works in Arista switches with OSFP ports that support this optic. Send us your switch model and EOS version and we will check it against Arista's Transceiver and Cable Guide before dispatch, so you only receive a module that works in your port.
Does the 200G-2LR4 work with my existing QSFP-100G-LR4 optics?
Yes. It carries two independent 100GBASE-LR4 links and interoperates with QSFP-100G-LR4 at the far end. The host port must be configured as 2 × 100G.
Is your OSFP-200G-2LR4 genuine Arista?
Yes. Next Gen Networks supplies original Arista Networks optics, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch, and we share the serial numbers on request so you can verify them in EOS ('show inventory').
What is the OSFP-200G-2LR4 price in India and how do I order?
The Arista OSFP-200G-2LR4 price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
How much power does the OSFP-200G-2LR4 draw?
Arista lists maximum power of 8 W for the OSFP-200G-2LR4. Check your switch's per-port power budget for dense deployments.
