Description

Gigaopto’s QSFP28 CWDM4 transceivers (P/N GTQ-L27B4-02DC) are designed for use in 100 Gigabit Ethernet applications,a max distance can up to 2km over G.652 single mode fiber(SMF) via an duplex LC connector.

The module converts 4 input channels of 25.78Gb/s electrical data to 4 channels of CWDM4 optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module demultiplexes a 100Gb/s optical input into 4 channels of CWDM4 optical signals and then converts them to 4 output channels of electrical data.

The module is with the QSFP28 38-pin connector to allow hot plug capability. The internally ac coupled high speed serial I/O simplifies interfacing to external circuitry. Only single 3.3V power supply is needed.

A serial EEPROM in the transceiver allows the user to access transceiver digital diagnostic monitoring and configuration data via the 2-wire QSFP28 Management Interface. This interface uses a single address, A0h, with a memory map divided into a lower and upper area. Basic digital diagnostic data is held in the lower area while specific data is held in a series of tables in the high memory area.

This 100G CWDM4 2km transceiver is compliant with IEEE 802.3ba, IEEE 802.3bm, 100G CWDM4 MSA, SFF-8665, SFF-8636 and ITU-T G.694.2 standards. With these features, it is suitable to be used in various applications, such as data centers, high-performance computing networks,enterprise core and distribution layer applications.

FAQ:

1. What is the advantage of the CWDM modules? Is there any difference from the usual one?

A:CWDM can provide larger transmission capacity, saving optical fiber resources(signals of different rates and formats can be mixed, as long as the rates at both ends of the combined wave front and the split wave rear are consistent)
