General The OS4016 is a 16 Channel E1 fibre optic multiplexer / de-multiplexer.
The high speed multiplexing format conforms to the ITU multiplexing format.
The unit is housed in a 3U high, 19? rack-mount enclosure. Basic System Description The unit is of modular design, and can be configured with different Optic and Power Supply modules. The six different components : 1. Rack ? 3U high 19?Rack Mechanics and Backplane.
2. PSU ? Power Supply Module.
3. 4xE1 MUX ? 4 Channel E1 to E2 Multiplexing Card.
4. HSMUX ? 4 Channel E2 to E3 Multiplexing Card.
5. OPTIC ? High Speed Data Encoder / Decoder & Optic Transceiver Card.
6. MANAGEMENT ? Optional System Management Card. The four 4 Channel Line Cards are fully interchangeable, and can be replaced separately - providing ease of maintenance.
Each one of the four E1 Line Cards multiplexes four E1 data channels into an E2 data stream. The four E2 data streams from the four line cards are then multiplexed together into an E3 high-speed data stream. Finally, the E3 data stream is CMI encoded, and then transmitted onto the fibre. The fibre receive path performs the exact opposite function ? decoding & demultiplexing the high-speed optic data back into the 16 separate E1 data channels.
The equipment meets or exceeds the industry specifications, including ITU G703. The unit conforms to both (ITU) G.742 and G.751 multiplexing format defined by the ITU. (Formerly known as CCITT)
Features - Crystal-less Jitter Attenuation.
- 75W and 120W I/O (selectable)
- High Transmit and Receive return loss.
- Simple Network Management available.
