Description

The QSFP56-200G-AOC is a Hot-Pluggable, Multi-Mode fiber for 200G short range of datacom interconnnection. Using VCSEL devices for 4 lanes,each electrical lane convert into optical lanes at 53.125Gbps giving an aggregated data rate of 212Gbps .It allows communication up to 70m using OM3 fiber or  100m using OM4  fiber with FEC. Compliant with the Common Management Interface Specification and MSA. This module incorporates proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.

Note:

1. RMS spectral width is the standard deviation of the spectrum.

2. Even if the TDECQ <1.4 dB, the OMA (min) has to exceed this value.

3. Ceq is a coefficient defined in 121.8.5.3, which accounts for the reference equalizer noise enhancement.

4. If measured into type A1a.2 or type A1a.3, or A1a.4, 50 μm fiber, in accordance with IEC 61280-1-4:2009

5. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level on one lane. The receiver does not have to operate correctly at this input power.

6. Average receive power, each lane (min) is not the principal indicator of signal strength. A received power below this value cannot be compliant; however, avalue above this does not ensure compliance.

7. Measured with conformance test signal at TP3 (see IEEE802.3 138.8.10) for the BER specified in 138.1.1.

8. Receiver sensitivity is optional and is defined for a transmitter with a value of SECQ up to 4.5 dB.
