QSP28 100GBase ER4 Module White Paper

Overview:

Q28QD040C05D is a high performance QSFP28 transceiver module for 100 Gigabit Ethernet data links over a single mode fibre pair. The maximum reach is 40km. The four transmitters are cooled 1310nm LAN-WDM lasers generating four optical 25Gbps output signals, which are multiplexed together at the optical output port. The four receivers are PIN photodiodes which detect (after optical de-multiplexing) 4× 25Gbps optical input signals. This transceiver module is compliant with the QSFP28 Multisource Agreement (MSA) and hot pluggable.

Features

• QSFP28 Multi-Source Agreement compliant
• Hot pluggable QSFP28 footprint
• Supports 103.125 Gbps Data Rate
• Dual LC Connector
• 4´ 25.781Gbps Serial Electrical Interface (CEI-28G-VSR)
• 4´ cooled 1310nm LAN-WDM Transmitters
• 4´ PIN+SOA Receivers
• Up to 40km Point-to-Point Transmission on Single Mode Fibre
• Operating temperature range 0°C to 70°C
• Power Dissipation < 5W
• Single +3.3V Power Supply

Applications

• Data Centre Interconnect (DCI)
• Metro P2P
• Enterprise(Links between buildings, Connections between Enterprise and Metro Access locations)

Key characteristics

• Power consumption of 5.5W average at 70 C
• Power consumption of 4.5W average at 35 C
• Supports 40km without FEC

Compatibility:
