Multilink optical transponder transmits up to 100km

The MTC21218 optical transponder from Multilink Technology Corp. is capable of transmitting up to 100km, and is targeted for use in DWDM systems, MANs, IP routers, and ATM switches.

The 114-by-89-by-13mm device supports data rates of 9.9Gbps, 10.3Gbps, and 10.7Gbps for both 80km and 100km applications. It uses a CW DFB laser and LiNbO3 Mach-Zehnder modulator to achieve a fiber output power of up to 7dBm.

The transponder is compatible to the 300-pin MSA and integrates the company's MTC5529 12.5Gbps modulator driver (MDR), MTC1235 10Gbps MUX-CMU, and MTC1236 CDR-DMUX chipset. It also features a low-chirp transmitter and is available with either PIN or avalanche photodiodes on the receiver side.

The MTC21218 is compliant with the Bellcore GR-253-CORE, ITU-T G.691, G.692, G.709, G.825 and OIF99.102.5 standards, and is claimed by the company to exceed the ITU-T G.691 jitter requirements.

The MTC21218 is priced at $14,000 for volume quantities of 1,000 units. The MTC5529 is quoted at $700 in volume quantities of 5,000. The MTC1235 and MTC1236 are priced at $425 in quantities of 1,000.

The company also offers a non-WDM version that transmits up to 100km without the need for optical pre-amplifiers.
