Additional verified details

• Module description — The 4100‑Series Quad OTDR module combines both multimode (850/1300 nm) and single‑mode (1310/1550 nm) testing in one module to avoid swapping modules for mixed networks.
• Multimode certification — The module supports Tier‑2 premises certification and includes propagation delay measurement to meet TIA‑568‑C multimode requirements when used with the appropriate modal controller.
• Ports and accessibility — The integrated light source and power meter are accessible through both OTDR ports (MM and SM), enabling fiber identification and basic power checks without changing ports.
• T‑BERD/MTS‑5800 V2 mainframe highlights — The 5800 V2 platform is a field‑upgradeable, battery‑operated test mainframe designed for high‑density field testing; typical mainframe features include a high‑resolution touchscreen, Linux‑based OS, and multi‑hour battery operation depending on test type.
