Specification for 1U rack type 96 core
porous high density distribution frame
Basic Information:
1. Product name: 1U rack type 96 core porous high-density optical fiber distribution frame
2. Product use: Used in data center, telecom room, enterprise network and other places of optical fiber
connection and management, realize the centralized wiring of optical fiber lines, transfer, scheduling
and other functions.
2. Physical Specifications:
1. Size:
1. Height: 1U, about 44.45mm.
2. Width: 19 inches, or 482.6 mm, meets standard rack installation requirements.
3. Depth: 250mm
2. Weight: generally 3.5kg
3. Type of optical fiber interface:
1. Common support MPO, LC and other interface types. If MPO interface is used, it can usually be
configured to install multiple MPO pre-termination boxes to achieve 96 core connection. For example,
four 24-core MPO pre-termination boxes can be installed. If the LC interface is used, since each LC
duplex coupler occupies two fiber ports (one transmit and one receive), a maximum of 48 LC duplex
couplers can be supported, that is, 96 fiber ports.
4. Performance parameters:
1. Nominal working wavelength: According to different application scenarios and fiber types, it
supports 850nm (multi-mode), 1310nm (single-mode), 1550nm (single-mode) and other common fiber
communication wavelengths.
2. Insertion loss: for MPO interface, insertion loss is generally ≤0.7dB; For the LC interface, the
insertion loss is usually ≤0.5dB. Products from different manufacturers may vary slightly.
3. Return loss: the return loss of LC interface is generally PC≥40dB, UPC≥50dB, APC≥60dB; The
return loss of MPO interface varies according to the specific structure and connection mode, but
generally it should also meet the high return loss requirements to ensure the quality of signal
transmission.
4. Electrical strength: ≥3KV (DC) /1min no breakdown, no flying arc, to ensure safe use in normal
第 1 页 共 2 页electrical environment.
5 Insulation resistance: ≥1000MΩ/500V (DC), to ensure good insulation performance, prevent signal
interference and leakage and other problems.
6. Fiber bending radius: the bending radius of the internal fiber should be ≥30mm (static) and ≥
20mm (dynamic) to ensure that the bending degree of the fiber in the distribution frame will not affect
the signal transmission.
5. Structure design:
1. Frame structure: the use of high-strength metal materials, cold rolled steel plate to ensure that the
distribution frame has sufficient strength and stability, can withstand long time use and a certain degree
of external force impact. The surface is treated with anti-rust and anti-corrosion, such as spraying and
galvanizing.
2. Tray or module box: it is equipped with multiple trays or module boxes for installing components
such as fiber adapter and MPO pre-termination box. The tray or module box should have good fixing
and positioning functions to ensure the stability of the fiber connection.
3. Wire handling device: it is equipped with reasonable wire handling device, such as wire handling ring,
wire handling slot, etc., which is convenient for sorting and fixing the fiber jumpers, so that the jumpers
are arranged neatly and orderly, which is easy to manage and maintain.
4. Labeling system: with a clear label position or label slot, it is convenient to mark and identify each
fiber port, so that the fiber connection can be quickly found and located.
6. Installation and compatibility:
1. Installation: support standard 19-inch rack installation, fixed on the rack by means of screws or clasp,
simple and firm installation.
2. Compatibility: compatible with the mainstream fiber jumpers, connectors, optical modules and other
equipment on the market, can be used with different manufacturers, different types of network
equipment for good cooperation
