• Compliance

ONS15454 SDH optical cards, when installed in a system, comply with these standards:

–

Safety: IEC 60950, EN 60950, UL 60950, CSA C22.2 No. 60950, TS 001, AS/NZS 3260, IEC

60825-1, IEC 60825-2, 21 CFR 1040-10 and 21 CFR 1040.11.

–

Class 1M (IEC 60825-1 2001.01) and class I (21 CFR 1040.10 and 1040.11) laser product

Note The optical output power of the OC192 LR/STM64 LH 1550 (+7 dBm to +10 dBm) is 3 dB lower

than in L-64.2b of the pre published unedited version 10/2000 of ITU-T G.691 (+10 dBm to +13

dBm). However, the total attenuation range of the optical path, 22 to 16 dB, is maintained by the

optical receiver sensitivity range of the OC192 LR/STM64 LH 1550 (-9 dBm to -17 dBm). This

sensitivity range outperforms the specification in L-64.2b of the pre published unedited version

10/2000 of ITU-T G.691 (-14 dBm to -3 dBm).

3.26 E100T-G Card

The E100T-G card provides twelve ports of IEEE 802.3-compliant, 10/100 interfaces. Each interface

supports full-duplex operation for a maximum bandwidth of 200 MBits/s (Mbps) per port and 2.488

GBits/s (Gbps) per card. Each port independently detects the speed of an attached device (auto-senses)

and automatically connects at the appropriate speed. The ports auto-configure to operate at either half

or full duplex and can determine whether to enable or disable flow control. Figure 3-43 shows the card

faceplate and Figure 3-44 shows a block diagram of the card.
