L-band Matrix 8 х 24 M0824D4UFL-B7B7-A
Производитель: ETL
Страна: Великобритания
L-band Matrix M0824D4UFL-B7B7-A: 8 Inputs x 24 Outputs Distributive, designed especially for cruise ship applications, with dual redundant power supplies and 75 Ω BNC connectors
ETL has a broad L-band Switch Matrix and L-band Router range for Satellite communications, including the hot-swap NiGMa L-band Matrix which is used for many high resilience high performance applications.
This smaller range of distributive L-band Matrix comes in a variety of size configurations which are generally linked to original design applications. The 2U 8x8 L-band Matrix and 3U 16x16 L-band Matrix are standard building blocks for most applications with dual redundant PSU's, a CPU and local control panel. Remote control is via serial or Ethernet.
More specialist is the 8x24 L-band Router is 4U and optimised for asymmetric dual antenna cruise ship matrices. Likewise the 8x16 (2U) and 4x8 (2U) and 1U SNG truck matrices are designed for specific applications.
While some of the L-band matrix products in this range have hot-swap power supplies, please see our Hot Swap Matrix range for matrices with hot swap of RF modules, CPU's and PSU's.
Non-blocking: this means any input can be routed to any output.
In general our solid state (L-band) matrices are non-blocking.
Full Fan-out Matrix (or fully distributive or splitting matrix): any input can be routed to any output. One input can be routed to many outputs. Each output can only have one input. Tends to be more RX.
8 x 24 L-band Matrix With local and remote control (via RJ45 Ethernet Port & RS232/422/485 Serial Port) Designed for ships
The ETL 4U L-band distributive matrix is a high performance switch matrix (or router) with up to 8 inputs and 24 outputs, integrated power supplies and matrix controller in a 4U high shelf. The matrix design is ideal for marine applications, which have non-symmetric satellite downlinks in terms of number of inputs and outputs. Offering the matrix in a single unit enhances RF performance, reduces cost and is faster to install than traditional solutions.
The matrix incorporates a standard ETL controller which can be remotely controlled via either a PC (using ETL software) or integrated into an M & C system. Dual redundant integrated power supplies provide security against the impact of unforeseen failure.
In the event of total power failure, all matrix settings are retained. The unit can be supplied in a partially populated state but the units must be returned to base for later expansion or maintenance. This particular unit has 50 ohm BNC connectors, but other impedances and connector types are available.
