MPO 100m Fiber Transceiver Module Cisco 100G Base SR4 QSFP28 MMF 850nm
Description
Cisco Compatible 100GBase SR4 QSFP28 MMF 850nm MPO 100m Transceiver
Module manufactured by ANC International Co., Limited is a
parallel 100Gb/s Quad Small Form-factor Pluggable (QSFP28) optical
module. It provides increased port density and total system cost
savings. The QSFP28 full-duplex optical module offers 4 independent
transmit and receive channels, each capable of 25Gb/s operation for
an aggregate data rate of 100Gb/s on 100 meters of OM4 multi-mode
fiber.
An optical fiber ribbon cable with an MTP/MPO connector can be
plugged into the QSFP28 module receptacle. Proper alignment is
ensured by the guide pins inside the receptacle. The cable usually
cannot be twisted for proper channel to channel alignment.
Electrical connection is achieved through an MSA-compliant 38-pin
edge type connector.
The module operates by a single +3.3V power supply. LVCMOS/LVTTL
global control signals, such as Module Present, Reset, Interrupt
and Low Power Mode, are available with the modules. A 2-wire serial
interface is available to send and receive more complex control
signals, and to receive digital diagnostic information. Individual
channels can be addressed and unused channels can be shut down for
maximum design flexibility.
The product is designed with form factor, optical/electrical
connection and digital diagnostic interface according to the QSFP28
Multi-Source Agreement (MSA). It has been designed to meet the
harshest external operating conditions including temperature,
humidity and EMI interference. The module offers very high
functionality and feature integration, accessible via a two-wire
serial interface.

Notes:
1. Even if the TDP < 0.9 dB, the OMA min must exceed the minimum
value specified here.
2. See Figure 5 below.
3.The receiver shall be able to tolerate, without damage,
continuous exposure to a modulated optical input signal having this
power level on one lane. The receiver does not have to operate
correctly at this input power.
4.Measured with conformance test signal at receiver input for BER =
1x10-12.
