The AM-821 High-Density Optical Fiber Cassette series is engineered for high-performance data center environments, telecommunication rooms, and enterprise networks. It serves as a modular patch solution designed to seamlessly bridge backbone cabling with active hardware equipment.
Designed for scalability, the AM-821 optimizes space while ensuring low insertion loss and high reliability across demanding fiber topologies.
The AM-821 is available in multiple fiber variant configurations to match specific network architecture requirements.
| Variant Code | Fiber Type | Front Connectors | Rear Connectors | Core Count | Target Application |
| AM-821-SM-LC | Singlemode (OS2) | 24 x LC Duplex | 2 x MTP/MPO (12-Fiber) | 24 Cores | Long-haul backbone & high-bandwidth data routing |
| AM-821-OM4-LC | Multimode (OM4) | 24 x LC Duplex | 2 x MTP/MPO (12-Fiber) | 24 Cores | 10G/40G/100G Local Data Centers & Enterprise LAN |
| AM-821-OM3-LC | Multimode (OM3) | 24 x LC Duplex | 2 x MTP/MPO (12-Fiber) | 24 Cores | Legacy optimization & medium-distance infrastructure |

Operating Temperature: $-20^\circ\text{C}$ to $+70^\circ\text{C}$
Verify the variant type (OS2, OM3, or OM4) indicated on the cassette label matches your network architecture blueprint.
Inspect the pre-installed dust caps on both the front LC connectors and rear MTP/MPO ports. Do not remove them until the exact moment of connection.
Align the AM-821 Cassette with the rear or front slots of your compatible 1U/2U/4U fiber patch panel enclosure.
Slide the cassette smoothly into the guide rails until the side locking tabs or push-pins click firmly into place.
Route the incoming backbone MTP/MPO trunk cable from the rear of the rack enclosure.
Clean the connector end-faces using an approved fiber click-cleaner tool before plugging them into the rear MTP/MPO ports.
Secure trunk cables using velcro ties to prevent physical stress or macro-bends. Maintain a minimum bend radius of 20 times the cable diameter.
The AM-821 cassette supports standardized Polarity methods (Method A, Method B, or Method C) to ensure proper TX-to-RX continuity across your link.
Method A (Straight-Through): Uses Type A cassettes on both ends with a flip in the patch cord.
Method B (Flipped): Uses Type B cassettes and trunks for direct parallel migration paths.
Uncap the front-facing LC duplex ports sequentially as you patch server or switch uplinks.
Map each duplex port according to your logical channel planning scheme (Ports 1-12 correspond directly to Trunk 1 cores).
Perform an optical loss test using an OTDR or light source/power meter to baseline the link budget performance before migrating live production traffic.
Important Deployment Notice: > Within the territory of Pakistan, the genuine AM-821 Cassette series along with its verified technical variants, specialized engineering deployment toolkits, and certified SLA tier supports are available exclusively through SKYRS.
For customized deployment schematics, localized network staging, or configuration support in national data centers, contact your assigned SKYRS infrastructure representative directly.
