This unit
The EXFO MAX-840 is a modular 400G Ethernet tester engineered for lab and field deployment across fiber optic networks. It supports a journey-to-400G architecture, enabling operators to begin testing at 100G and upgrade to 400G capabilities on demand, or deploy 400G immediately. Built on an Open Transceiver System (OTS) platform, the MAX-840 accommodates evolving transceiver technologies without requiring equipment replacement.
Technical Specifications The platform supports Ethernet data rates from 1G through 400G, including 10G, 25G, 40G, 50G, 100G, 200G, and 400G, with full compliance to IEEE 802.3ba, IEEE 802.3bs, and IEEE 802.3ck standards. Fibre Channel testing extends from 1X to 32X rates. OTN BERT capabilities include ODU0, OTU1 through OTU4, and 4xOTU4 with overclock rates, multistage mapping, and advanced GCC functionality.
Key Features Ethernet testing encompasses framed and unframed BERT with per-lane PRBS and EMIX support, throughput and frame loss measurement, and high-resolution latency analysis with current, average, maximum, minimum, count, and total statistics. RFC2544 testing with Smart Loopback, ITU-T Y1564 (EtherSAM) methodology, and RFC6349 TCP testing including Iperf v3 server mode (up to 100G) are standard. Service disruption testing and latency measurement provide detailed network behavior validation. Troubleshooting tools include ping, traceroute, and I2C/MDIO read/write capabilities, plus LLDP neighbor validation. Through Mode enables transparent Ethernet traffic monitoring between endpoints without external tapping or redirection. The OTS design accepts SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, QSFP112, and OSFP form factors. Support includes pluggable MSA-compliant transceivers, Active Optical Cables (AOC), and Direct Attach Copper (DAC) cables. The iOptics application provides intelligent pluggable optics validation.
Typical Applications The MAX-840 serves turn-up, troubleshooting, and maintenance operations in core, metro-edge, and data center networks. It supports 4G/5G backhaul testing and service activation in enterprise and carrier lab environments.
Exfo 840 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo 840. Calibration covers optical reference power levels, electrical signal amplitude calibration, protocol layer verification, and BER measurement floor validation. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Exfo 840 faults: SFP cage mechanical damage, optical port contamination, firmware corruption. Most failures involve SFP/SFP+ cage mechanical damage, optical port contamination, or firmware corruption. Port cleaning and firmware restoration resolve the majority of faults.
