Product Description:

The Coherent HL-QSFP28-DCO QSFP28 Digital Coherent Optics (DCO) transceiver supports 100G transmission over distances up to 120km (dispersion limited, optionally extendable to 300km) for edge network applications. On the host side, the module can accommodate IEEE 100GE Ethernet or ITU-T OTN OTU4 signals. The line side coherent interface specifications are aligned with IEEE Std. 802.3-2022 100GBASE-ZR [8] and ITU-T G.698.2 DW50U-8A2(C)F / DW100U-8A2(C)F [11], which define a 27.95GBd dual-polarization differential QPSK modulation format.

The module is offered in both commercial temperature (0°C to 70°C) and industrial temperature (-40°C to 85°C) versions, with power dissipation of less than 6.0W. The local oscillator laser is full C-band tunable and the transceiver can optionally be configured to support FlextuneTM automatic wavelength tuning.

The transceiver module is compliant to the Specification for QSFP+ 28 Gb/s 4X Pluggable Transceiver Solution (QSFP28) [1] and specifications referenced therein [2-7]. The transceiver is RoHS compliant and lead-free per Directive 2011/65/EU [19].
