QSFP-100G-PLRL4: frequently asked questions
What is the Arista QSFP-100G-PLRL4?
The Arista QSFP-100G-PLRL4 is a QSFP28 100GBASE-PLRL4 module from Arista Networks for 100 Gbps / 40 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-PLRL4?
Arista specifies the QSFP-100G-PLRL4 for 2 km on parallel single-mode fiber; 100G/40G dual rate.
What are the transmit and receive power levels of the QSFP-100G-PLRL4?
Per Arista's published optics data sheet, the QSFP-100G-PLRL4 transmits −5.5 to +1.5 dBm/lane and receives −12.6 to +2.0 dBm/lane.
Which fiber and connector does the QSFP-100G-PLRL4 need?
The QSFP-100G-PLRL4 uses a MPO-12 APC connector on parallel single-mode (G.652), at 1310 nm. APC connectors have an angled (green) end-face, so use APC patch cords and trunks. Both ends of the link must use the same optical standard.
Is the QSFP-100G-PLRL4 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 single-mode optic should I choose?
Up to 500 m: DR or PSM4. Up to 2 km: FR, CWDM4, LRL4 or PLRL4. Up to 10 km: LR, LR4, XCWDM4. Up to 40 km: ER or ERL4. Up to 80 km: ZR4. Both ends of a link must use the same optical standard (or a pair Arista lists as interoperable).
Does the QSFP-100G-PLRL4 support breakout?
Yes. Arista lists breakout to 4 × 25G / 4 × 10G. Use the matching optics at the far end and a suitable breakout cable or patch panel.
Is your QSFP-100G-PLRL4 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-PLRL4 price in India and how do I order?
The Arista QSFP-100G-PLRL4 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.
