Quick definitions for fiber access & ELV acronyms
Fiber from the central office to residential units. Typically built on GPON or XGS-PON, with indoor ONT/ONU at the home.
Enterprise architecture delivering fiber to floors/zones with passive splitting; also called POL (Passive Optical LAN).
Extends fiber to rooms/suites (hotels, residences) for IPTV, VoIP and Wi-Fi APs with minimal copper.
Passive optical standard: 2.5 Gbps downstream / 1.25 Gbps upstream; typical split ratios 1:32–1:128.
10 Gbps symmetrical PON; coexists with GPON on the same ODN; good for premium broadband and enterprise POL.
Emerging standard offering much higher split capacity with wavelength coexistence on existing ODN.
Provider-side chassis that terminates PON and aggregates traffic towards the core; houses service cards and optics.
Customer-premises device that terminates the fiber and provides Ethernet/voice/Wi-Fi interfaces.
Splits optical power from one feeder into multiple drops (e.g., 1:32). Insert loss must be in the budget.
Outdoor/indoor enclosures where splitters/patching connect feeder to distribution/drop fibers.
Tests fiber links by sending pulses and analyzing backscatter; detects splice/connector losses and breaks.
Defines uptime, response, and MTTR targets; OLA aligns internal teams to meet SLA.
VLAN separates services/users at L2; QoS prioritizes real-time traffic (voice/video). Common in FTTO/POL.
Passive outside/inside plant between OLT and ONTs: cables, splitters, closures, FAT/PDO, and drops.
Rack/cabinet housing fiber patch panels, splice trays and cable management at central sites.
Sealed enclosure protecting fusion splices in outside plant; supports trays, slack and branching.
Miniature ducts installed in bundles to allow blown fiber or mini-cables with low friction.
Method to install fiber using air pressure through microducts; scalable and less disruptive.
Common SMF with low water peak; used widely in access and metro networks.
Improved bend performance ideal for indoor drops and tight spaces.
APC angled (≈8°) for low back-reflection; UPC flat/ultra-polish. Do not mix types.
Pigtail is a short fiber with one connector for splicing; patch cord (jumper) with two connectors for patching.
Signal power reduction per length/component; summed when calculating link budget.
Absolute power referenced to 1 mW. Receivers have min/max dBm windows for error-free operation.
Sum of fiber loss + splices + connectors + splitters ≤ transmitter power − receiver sensitivity.
Total reflected power back toward the source; higher (more negative dB) is better. Use APC to improve.
Multiplex multiple wavelengths on one fiber. CWDM wide-spaced, DWDM dense—higher capacity.
Adds or removes selected wavelengths without converting to electrical—used in ring/linear systems.
Minimum allowable bend to avoid excess loss or breaks; better with G.657 fibers.
Typical fusion target ≤0.05–0.1 dB per splice; affected by cleave quality & cleanliness.
Always inspect → clean → inspect connectors. Dust is #1 cause of high loss/ORL.
Region near the OTDR where events can’t be resolved; use launch/receive fibers to see first/last connectors.
Measures received dBm at specific wavelengths; used with a stable light source for end-to-end loss.
Stable laser/LED generating 1310/1550/1490/1625 nm; pair with power meter for insertion loss tests.
Red laser pen for continuity and macro-bend checks; not for precise loss measurement.
IEEE 802.3af/at/bt power over Ethernet for APs, cameras, phones. Ensure cable gauge & power budget.
OFDMA, BSS coloring, 6 GHz (6E) for dense deployments; still backhauled by fiber.
Combines multiple Ethernet links for higher throughput and failover; requires matching configs.
Spanning Tree variants to prevent L2 loops; MSTP maps multiple VLANs to instances.
Collects metrics, traps and status from OLT/ONT and ELV devices; base for SLA reporting.
Authentication, Authorization, Accounting for users/devices (e.g., 802.1X, captive portal).
Web-based login/sponsorship for guest Wi-Fi; integrates with AAA and usage policies.
Uninterruptible power and redundant PSUs for OLT/switch/NVR to meet uptime targets.
Plan RU space, depth and airflow for OLTs, patch panels, power and cable management.
Common earthing and bonding for racks, trays and shields to reduce faults and noise.
Seal cable penetrations with certified systems to maintain fire ratings and compartmentalization.
Final drawings reflecting the installed network; redlines capture field changes during build.
Process to certify links, deliver OTDR/Power test packs, and transfer operations to O&M.
Procedures and PPE for safe works (confined spaces, heights, hot works) and incident prevention.
