The series consolidates OTDR, stabilized light source, optical power meter, visible light source, and optional IP test functions into a single compact instrument, eliminating the need to carry multiple separate test sets to the work site. Three performance tiers are available: the MT9083A general-purpose model, the MT9083B high-performance model, and the MT9083C ultra-high-performance model, each available in standard indoor or enhanced indoor/outdoor display variants. The ACCESS Master is used for optical fiber construction, certification, fault location, and ongoing maintenance across both single mode and multimode fiber plants. Dedicated testing modes built into the firmware address specific tasks: Fault Locate mode automates parameter selection and returns end or break location for occasional users, Standard OTDR mode supports manual setup for experienced operators, and Construction mode provides a wizard-driven workflow for multi-wavelength cable acceptance with consistent file naming. Additional modes cover stabilized light source operation, optical loss test set measurements, visual fault location, and IP connection testing when the corresponding options are installed. The instrument also supports remote SCPI command operation for automated test integration and unmanned monitoring. ValueTronics International stocks, inspects, and ships the MT9083 Series ACCESS Master from a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Each {{CONDITION}} unit moves through documented receiving, performance verification against the manufacturer's published OTDR specifications, and condition grading by technicians on site before it is offered for sale, so the configuration the buyer receives matches the configuration described in the listing. This in-house handling distinguishes ValueTronics from pass-through brokers and unverified marketplace listings where the seller has not physically tested the instrument. ## Compare Other Models in This Series The MT9083 Series ACCESS Master is organized into three performance tiers that share a common physical platform, user interface, and accessory ecosystem. The MT9083A is the general-purpose base model, the MT9083B is the high-performance tier with enhanced dynamic range and dual-mode High Resolution / Enhanced Range operation, and the MT9083C is the ultra-high-performance tier with the longest distance range, the highest dynamic range, and up to 150,001 sampling points. Within each tier, the datasheet defines a numbered option suffix (for example -053, -057, -063) that specifies the wavelength configuration, fiber type, and whether the unit is single mode, multimode, or hybrid. Display variants are designated with a trailing '1' (MT9083A1, MT9083B1, MT9083C1) for the enhanced indoor/outdoor display; base part numbers without the '1' carry the standard indoor display. All tiers share the same external interfaces, data formats, and software options. Each model linked below is its own product page with pre-owned-matched pricing and the option suffix called out in the title. Confirm the wavelength configuration, the optical connector type, and any installed software or hardware options on the specific listing before ordering — the MT9083 platform supports many factory-installed and retrofit options that materially change what the unit can measure. The three tiers differ primarily in dynamic range, distance range, and sampling resolution. The MT9083A series provides up to 38.5 dB dynamic range (1310 nm, 20 µs pulse, 180 s averaging) and up to 200 km single mode distance range. The MT9083B series provides up to 42 dB dynamic range with dual-mode High Resolution / Enhanced Range operation and Enhanced Mode optimized for 1×64 PON characterization, also at up to 200 km. The MT9083C series provides up to 45 dB dynamic range, up to 300 km single mode distance range, up to 150,001 sampling points, and Enhanced Mode optimized for 1×128 PON characterization. Wavelength configurations also differ across option suffixes within each tier. The -053 option provides 1310/1550 nm single mode and is common across all three tiers. The -055 option adds 1650 nm with integrated filter for live-fiber work. The -056 option adds 1490 nm for FTTx/PON verification.

The optical configuration option (defining the OTDR wavelengths) must be ordered separately and specified at time of order.**Important:** Optical connector adapters must be specified at time of order. UPC and APC connectors are not compatible — the internal optics are different. FC-APC (option -025) and SC-APC (option -026) connectors are not available for the multimode OTDR port or Optical Power Meter, and an additional charge applies for these connector types.**Important:** The Gigabit Ethernet Upgrade (option MT9083A/B/C-011) requires option MT9083A/B/C-001 (IP Network Connection Check Function). The retrofit Gigabit Ethernet Upgrade (option MT9083A/B/C-111) requires option MT9083A/B/C-001 or MT9083A/B/C-101.**Important:** If optional power meter option 004, 005, or 007 is ordered, the standard integrated power meter is not available.**Important:** Retrofit options (-101, -102, -104, -105, -107, -110, -111) require the unit to be returned to an authorized Anritsu service center for installation.Recommended pairing: order the OPTION-545VIP Connector Video Inspection Probe alongside the ACCESS Master to inspect connector end faces before OTDR measurement, per the datasheet's All-in-One Tester configuration. ## About this used unit - Warranty included - Functional verification included - Standard Calibration Upgrade Options: No Calibration Required, NIST Traceable, Z540.1 or ISO 17025 with Data, Z540.3 Guardbanding with Data. - Note that unnecessary accessories may not be included (contact Test Architect to confirm). **Please review the Manufacturer's Data Sheet to verify published specifications.
