QSFP-100G-SR4: frequently asked questions
What is the Arista QSFP-100G-SR4?
The Arista QSFP-100G-SR4 is a QSFP28 100GBASE-SR4 module from Arista Networks for 100 Gbps links. It plugs into a 100G QSFP port on an Arista switch and is used for 100G leaf-spine fabrics, DC interconnect, 4 × 25G breakout and service-provider aggregation.
What is the maximum distance of the QSFP-100G-SR4?
Arista specifies the QSFP-100G-SR4 for 70 m on OM3 and 100 m on OM4 parallel multimode fiber.
What are the transmit and receive power levels of the QSFP-100G-SR4?
Per Arista's published optics data sheet, the QSFP-100G-SR4 transmits −8.4 to +2.4 dBm/lane and receives −10.3 to +2.4 dBm/lane.
Which fiber and connector does the QSFP-100G-SR4 need?
The QSFP-100G-SR4 uses a MPO-12 UPC connector on parallel multimode (OM3/OM4), at 850 nm. Both ends of the link must use the same optical standard.
Is the QSFP-100G-SR4 compatible with my Arista switch?
It works in Arista switches with 100G QSFP 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.
Which Arista 100G multimode optic should I choose?
SR4 / SR4-E / XSR4 use 8-fibre MPO trunks (SR4-E adds a no-FEC low-latency mode, XSR4 extends reach to 300 m OM4). SWDM4, SRBD and SR1.2 run on ordinary duplex LC multimode, so existing 10G fibre pairs can be reused.
Does the QSFP-100G-SR4 support breakout?
Yes. Arista lists breakout to 4 × 25G-SR. Use the matching optics at the far end and a suitable breakout cable or patch panel.
Is your QSFP-100G-SR4 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 QSFP-100G-SR4 price in India and how do I order?
The Arista QSFP-100G-SR4 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 QSFP-100G-SR4 draw?
Arista lists maximum power of 3.5 W for the QSFP-100G-SR4. Check your switch's per-port power budget for dense deployments.
